Normalisation 3: grammar
examples of the levelling of stem alternation and other paradigm complexities or anomalies within eME paradigms
The following is background information. It is not required reading for these who wish to learn Early Middle English. If you're looking for a description of Early Middle English grammar, see eME language.
principles 3 & 4 - background
The sections below examine the application of principles 3 & 4, which are outlined at Normalisation 1: principles, and their role in the simplification of eME grammar. Frequent use is made of the abbreviations and definitions listed there.
Principles 3 & 4 are as follows:
- stem alternation and other complexities or anomalies within a given paradigm (noun, verb etc), are excluded from the core eME grammar when evidence of levelling exists in that paradigm in a text dated before 1250;
- a development observed within most members of a distinct group of words with shared characteristics, can be applied to each remaining member of that group, provided the development conforms with the ModE reflex (if it exists); this applies i.a. to
- levelling within paradigms (via principle 3 above)
- sound changes within a particular phonetic environment, e.g. vowel lengthening or shortening, elision or syncope, and consonant degemination
The upshot is that within certain paradigms inherited from OE, items are either merged or jettisoned, inflexions are reduced, and stem alternation and other paradigm complexities or anomalies are levelled. We also see the merging of weak verb classes. The result is a significant simplification of the core eME grammar.
levelling complete by 1150
There are two main threads that run through the story of Middle English (ME) - the simplification of the grammar inherited from Old English (OE) and the addition of vocabulary borrowed from French and Latin.
These two developments were not simultaneous. Much of the simplification of OE's grammar had taken place, in the Northumbrian dialect, and in the eastern part of the Mercian dialect area, before the end of the OE era. The influx of French and Latin words came later - a trickle at first before the mid-thirteenth century, and then a flood in the fourteeth and fifteenth centuries.
The grammatical innovations that leap from the pages of PC2 and Orm were mainly in the realm of nouns, adjectives and demonstratives. Three grammatical genders had become one. Ten classes of noun declensions (not counting sub-groups) had become one. Four noun cases had been reduced to three - the nominative (subject), the genitive (possessive) and the dative (following a preposition), though the latter was only sporadically appplied. Since the only remaining plural case ending was now identical to the genitive singular - -es, eight separate noun case forms had been whittled down to three.
Simplification to the verb system wasn't quite as dramatic by the end of the OE period, but was evident none the less.
The simplification of OE grammar, by the time it reaches eME, is essentially levelling within paradigms, and is threefold:
- a reduction in the number of items within paradigms (mainly noun and adjective);
- a reduction in the number of classes of paradigms (to a single class for nouns);
- a reduction in stem alternation and other complexities or anomalies within paradigms.
The levelling that had taken place in late OE, is not only evident in both PC2 and Orm, but is consistently applied. It is not dealt with here. For more detail, see the separate pages on the simplification of paradigms for nouns, adjectives, articles and verbs.
This page deals with levelling underway in the early Middle English period up to 1250.
core vs optional grammar
Two varieties or levels of eME grammar are used in this site - core and optional.
The changes to noun, adjective and verb paradigms which were complete by 1150, form the optional grammar of eME. Changes which simplify eME grammar further, and arise before 1250, are found in the core grammar but not in the optional grammar. In a nutshell, there is a greater degree of simplification in the core grammar.
Well begun is half done. In the case of levelling and the core grammar of eME however, well begun is enough. In short, levelling encountered in the early Middle English period, is incorporated in the core grammar of eME in this site, even if inconsistently applied. By the same token, any elements of OE grammar that are retained sporadically in East Midland texts, remain in the optional grammar of eME.
Note that I didn't place the word 'any' in front of 'levelling encountered in the early Middle English period' in the preceding paragraph. It is the application of principles 3 & 4 that determines the simplifications which pass to the core grammar of the eME used in this site.
There are two fundamental differences between the core and optional grammars. Beyond the milestone years for each - 1250 and 1150 respectively, there is also the degree of spread of the respective grammatical changes throughout the East Midland dialect. In the optional grammar that degree of spread is very close to total. There are very few, if any, exceptions. The grammatical simplifications introduced to the core grammar, on the other hand, are not universally applied. They may appear inconsistently in both PC2 and Orm or in only one of these texts. Some only appear in texts from dialect areas other than East Midland. Note also that examples of levelling may not be available for all paradigm forms in all of the nouns, adjectives and verbs in the groups identified. A degree of pattern extension is involved. This is discussed in more detail below.
the user perspective
The core grammar, which has fewer anomalies and exceptions, is aimed at the beginner. This is the grammar that appears in Audrey and the attercop, book 1 of Englisc buten taeres (the first 800 words). The optional grammar, which inherits more of OE's anomalies and exceptions, appears in normalised versions of OE and ME texts, and in the weblog of this site.
From the perspective of the ModE speaker, the core grammar is the smaller load to learn, while the optional grammar adds not only items, but also anomalies and complexities to paradigms, as well as classes to weak verbs.
Coming from OE, the optional grammar is the smaller departure, being more conservative, while the core grammar has the larger number of changes. In fact, when moving in this direction, the terms 'optional' and 'core' are somewhat counter-intuitive. For that reason I've bracketed the descriptors 'levelling complete by 1150' and 'levelling before 1250', after 'optional' and 'core' when referring to grammar in pages under 'OE to ME' (in the main navigation).
Crucially, the core grammar is the grammar presented in the reference pages for each of the main parts of speech under 'language' in the main navigation of this site. The optional grammar is presented in a single page under 'language'. For the ModE speaker it is effectively a list of add-ons to the core grammar of eME, which the user may wish to deploy in a translation or piece of original prose; hence the labels core and optional.
types of levelling
What sort of levelling is still underway in 1150 or arises before 1250, and is incorporated in the core grammar of eME? And what were the "distinct groups of words with shared characteristics" referred to in Principle 4 (above)? The following list provides an overview:
- removal of stem alternation in
- wa- and wo_-stem adjectives
- wa- and wo_-stem nouns
- a-stem nouns ending in <h>
- strong contracted verbs
- the fremmen and <cy%/y%> groups in class I weak verbs
- class III weak verbs
- loss of case forms
- dative in nouns
- accusative, genitive and dative in the indefinite article
- miscellaneous anomalies
- genitive marker absent in certain nouns (added)
- dual pronoun forms wit unk unker and y%it ink inker (dropped)
- syncope proscribed in the preterite of class II weak verbs (permitted)
- two stem vowels in the preterite of strong classes 4 and 5 (merged)
Some of these terms may not be familiar to you. A brief overview will provide further clarification below. Beyond that, all of the levelling listed above is discussed in detail in the separate pages on the simplification of paradigms for nouns, adjectives, articles and verbs.
core and optional side by side
Orm's variable approach to the noun tre__ and the verb hafenn/habbenn not only indicates a language in transition, but illustrates the differences between paradigms in the core and optional grammars rather neatly, in these two cases.
Traces of dual stems in some nouns and adjectives, can still be seen in Orm. Traces of dual stems are also evident in the present tense forms of certain verbs. However, and this is key - those traces are occasional and inconsistent. For every pair of tre trewwess Orm has tre tres (tree trees), and for every habbenn hafet`t` Orm has hafenn hafet`t` (have has). The anomalies trewes, trewe, habbe, habben are cut from the core grammar but remain in the optional grammar of eME.
Here's how the two pairs of paradigms line up:
sg. | nom./acc. | tre__ |
---|---|---|
gen. | trewes | |
dat. | trewe | |
pl. | (all cases) | trewes |
sg. | nom./acc./dat. | tre__ |
---|---|---|
gen. | tre__s | |
pl. | (all cases) | tre__s |
sg. | ic | habbe |
---|---|---|
t`u__ | hafest | |
he__/sce__/it | hafet` | |
pl. | we__/y%e__/hi__ | habben |
sg. | ic | hafe |
---|---|---|
t`u__ | hafest | |
he__/sce__/it | hafet` | |
pl. | we__/y%e__/hi__ | hafen |
The crux is that the core grammar has a single stem in both these cases - tre__ and haf~. Neither of these needs to be called out in the reference pages on nouns and verbs, since they behave just like the standard paradigms. The same is not true of course, for their counterparts in the optional grammar. Note also that the dative case is absent in the core grammar.
In Normalisation 1: principles I stated that "the Early Middle English used in englesaxe should be as simple and practical as possible for the learner" and "should reflect the broad patterns of development which led from Old English to Modern English". On that basis I have taken any reasonable opportunity to level within paradigms, provided those simplifications are supported by pre-1250 usage. That is the thinking which underpins principle 3.
Keep in mind that the grammar of the normalised eME in this site is based on the East Midland dialect alone. Generally then, only PC2, Orm, SO and Ch forms are considered. West Midland and Southern texts have no bearing in decisions on whether or not a conservative feature, inherited from OE, shoud be retained in the normalised eME of this site, though they may add weight to linguistic innovation which draws eME closer to ModE.
While Normalisation 2: additional eME forms deals with dictionary entry forms - the nominative of nouns, the infinitive of verbs etc, this page looks at all forms, i.e. changes to forms within noun, adjective and verb paradigms, due to case, number, strong/weak status, person, tense and mood i.a.
Note that the simplification of a paradigm can arise via principle 2 or principle 3. An example of the former is sec`g`an, saeg`t` > say%en, say%t` (to say, says). The infinitive form say%en which is supported by both PC2 and Ch, qualifies as an additional eME form via principle 2 and eliminates the dual stem for this verb in eME.
principles 3 & 4 in action
The key, particularly in regard to the early stages of learning a language, is to offer the simplest route. This is where principles 3 & 4 come into play. Where pre-1250 examples permit, stem levelling can be applied throughout a paradigm, and then throughout the entire group of nouns or verbs which share the characteristics of that paradigm.
Two examples - simplifying paradigms with dual stems
OE wa- and wo-stems have a dual stem. Inflected forms have a <w> at the end of the stem, while the nom sg (i.a.) does not. For example: bealu nom sg bealwes gen sg and sc`eadu nom sg sc`eadwe gen sg.
We can apply principles 3 & 4 to the eME reflexes of these nouns to remove that stem alternation in the core grammar of eME. The approach is as follows:
- we start with a noun paradigm that exhibits stem alternation, e.g. bale nom sg bal(e)wes gen/pl or scade nom sg scad(e)wes gen/pl;
- in a pre-1250 text we find a form which removes the stem alternation; this could be either an inflected form which drops the <w> or a nom sg which includes the <w>; e.g. bal(e)wes pl > bales pl and scade nom sg > scadew/scad(e)we nom sg;
- via principle 3 the stem levelling of one form (e.g. pl) is extended to the remaining form (e.g. gen sg) within the paradigm; so bales pl is extended to bales gen sg;
- courtesy of principle 4, the paradigm levelling of the majority of wa- and wo- stems can be extended to the remaining words in that group; e.g. the bale bales pattern is extended to mele meles and the scadew scadewes pattern to sinew sinewes;
Thus we have:
- pre-1250 forms which show stem levelling:
- inflected forms which drop <w>: bales pl, smeres gen, tres pl, cnes pl, ter dat, leohe dat;
nom sg forms which add <w>: barewe, t`eww, schadwe, mae_dwa m - principle 3 - extend stem levelling throughout paradigm:
- bale bales, smere smeres, tre__ tre__s, cne__ cne__s, tere teres, le__ le__s, barew barewes, t`ew t`ewes, scadew scadewes, maedew maedewes
- principle 4 - extend pattern of simplified paradigm to entire group:
- mele meles, sinew sinewes, straw strawes, laesew laesewes, sarew sarewess, badew badewess
The upshot is that the reflexes of OE wa- and wo-stems have a single stem in the core grammar of eME.
OE masculine a-stem nouns ending in <h> are a similar group with a dual stem. The nom sg and acc sg forms have a final <h>, while all other forms lose that <h> when the inflectional ending is added. We can apply principles 3 & 4 to the reflexes of these nouns to remove that stem alternation in the core grammar of eME. The approach is as follows:
- we start with a noun paradigm that exhibits stem alternation, e.g. walh nom sg wales gen/pl or wo__h nom sg wo__s gen/pl;
- in a pre-1250 text we find a form which removes the stem alternation; this could be either a nom/acc sg which drops the <h> or an inflected form which includes the <h> (or <g> etc); e.g. walh nom sg > wale nom sg and wo__ dat > wo__ge dat;
- via principle 3 the stem levelling of one inflected form (e.g. dat) is extended to the remaining inflected form(s) (i.e. gen/pl) within the paradigm; so wo__ge dat is extended to wo__ges gen/pl;
- courtesy of principle 4, the paradigm levelling of the majority of a-stems with final <h> can be extended to the remaining words in that group; e.g. the wale wales pattern is extended to sele seles and the wo__h wo__ges pattern to farh farges;
Thus we have:
- pre-1250 forms which show stem levelling:
- nom/acc sg forms which drop <h>: wale, mare, fere, feo, sho;
inflected forms which add <h> (or <g> etc): slo_ges gen, wo_ges gen, wo_ge dat, salhas pl, saligum dat pl, eolces gen, woge dat, wohe dat etc - principle 3 - extend stem levelling throughout paradigm:
- wale wales, mare mares, fere feres, fe__ fe__s, sco__ sco__s, slo__h slo__ges, wo__h wo__ges, elk elkes, salh salges
- principle 4 - extend pattern of simplified paradigm to entire group of nouns:
- sele seles, halh halges, farh fargess, alh algess, eh egess, horh horgess
The upshot is that the reflexes of OE a-stems ending in <h> have a single stem in the core grammar of eME.
See levelling in all pre-1250 sources (below) for more detail.
Extending the pattern
"Extending the pattern" is the key idea in both principles 3 & 4. In principle 3, the stem levelling of one form in a paradigm, is extended throughout that paradigm, while principle 4 allows us to extend the stem levelling pattern of one paradigm in a distinct group of words with shared characteristics, throughout all paradigms in that group.
This is a focus of the core eME grammar - generalising trends or patterns within particular groups of words. Each individual noun or verb form within a paradigm is not dealt with in isolation. Neither is each paradigm within an identifiable group of paradigms. Rather, observable patterns or trends are extended. Generally speaking, this involves the removal of stem alternation and other paradigm complexities or anomalies.
the ModE test
The ModE test is only invoked in two groups of words. The reflexes of the affected words in ME and ModE can show either of two possible forms. The question is - which form do we prefer in eME? How do we choose? In short, ModE indicates the preferred form for each word in question, provided that the sound change in question has begun to show at all within the group in the Early Middle English period.
This test is important because it means that we don't have to sift through the attested forms for each member of the group. We can apply a single test to all members of the group. And that test is a simple question - what form does ModE have?
For those familiar with OE, who prefer to use forms based on standard OE, these cases don't present a problem. But for those without that knowledge, seeking an appropriate (additional) eME form can be somewhat difficult at times, without the ModE test.
Imagine for example a ModE speaker who is looking for the eME word for flour. She has an OE dictionary (the CASD) in which she finds melu n, melwes gs. The word has two different stems. She suspects, from Principle 3, that there won't be stem alternation in the eME form. There will be a single stem for singular, plural and possessive. But will it have w or not? The appropriate forms are listed in Table X, but she is off-line temporarily (perhaps on a train) and doesn't have access to it. Not does she have access to the MED, and wouldn't have time to analyse the results, even if she did. If she bases the form on the OE nominative, it is mele. If she bases it on the OE genitive form, that's melwe. Which one is preferred?
This is where the ModE test comes in. There is no w in the ModE form - meal. So, instantly she knows that the preferred eME form is mele.
The ModE test applies in two contexts only:
-
with or without w/h?
The ModE reflexes of OE wa- and wo-stems sometimes have final w, and sometimes not: e.g. melu melwes > meal meal's (flour) but mae_d mae_dwe > meadow meadow's. Similarly, the ModE reflexes of OE a-stems sometimes have final gh (or w), and sometimes not: e.g. sco_h - sco_s > shoe shoes but slo_h - slo_s > slough sloughs (quagmire).
So how does a a ModE speaker know whether to include or exclude the w or h in an eME form? The answer is quite simply - look to ModE. If there is a ModE reflex without w or gh2, then leave out w or h in the eME form. Otherwise, include it. Hence - mele meles, maedwe maedwes, sco__ sco__s, slo__h slo__ges.
Note that where ModE has no reflex of an OE word, the eME form is based on the gen sg OE form (the form with the fickle w or h).
For more detail, see the simplification of verb paradigms and the simplification of noun paradigms.
-
vowel lengthening before consonant clusters ld, nd, ng, mb, rd
The vowel was short in OE but has since lengthened. Examples are: OE c`ild, hund, strang, climban > child, hound, strong, climb.
This development was inconsistent however. In many cases the vowel either remained short or reverted. Examples of short vowels before nd are ModE land, hand. On the other hand, both Orm and PH3 appear to have a long vowel in land and loand respectively. See normalisation 5: issues for further examples.
ModE is the guide. Since the language of departure is Modern English, and one of the aims of englesaxe is to provide a pathway to Old English, temporary sound changes in the Middle English period, have been ignored. In other words, if a vowel is short in an OE word, is indicated as long in Orm or Ch, but is short in the modern continuations of that word, it is short in eME.
If a vowel is short in an OE word which has not survived to ModE, for example - swindan, the corresponding vowel is short in eME. This is the case even when similar words - bi__nden fi__nden wi__nden, have a long vowel in ModE.
- ferien, herien > ModE ferry, harry
Examples of levelling underway in eME
The following grammatical features, were subject to levelling in the eME period:
- vowel alternation a/ae in preterite forms of strong verbs, classes 4 & 5 - y%af y%aefen
- stem alternation (with or without <w>) in reflexes of wa- and wo_-stems - bare barwes
- stem alternation in reflexes of a-stems ending in h - walh wales
- dative case marker -e for nouns ending in a consonant - tu__n tu__ne
- accusative form for indefinite article - a__n aenne
- dropping of unstressed penultimate syllable in genitive and plural - de__fel de__fles
- genitive forms without the -(e)s marker
The ensuing case studies provide some detail around the levelling of each feature. They are grouped according to the principle that comes into play, to remove the feature from the core grammar of eME.
Levelling underway in PC2 and Orm
This includes levelling found in either PC2 or Orm but not the other.
-
vowel alternation in the preterite forms of strong verbs, classes 4 & 5
This is a feature of OE. It is observed consistently in Orm, which has a for sg 1/3 and ae for the plural, e.g. sahh saey%henn, satt saetenn, spacc spaekenn, y%aff y%aefenn, but not in PC2 which usually displays the same vowel a for plural preterite forms, e.g. forbaren, namen, stali[n], drapen, iauen.
Core eME: single vowel - a in preterite of strong verbs, classes 4 & 5 - bar baren, y%af y%afen
-
dative case marker -e for nouns ending in a consonant
This is observed inconsistently in PC2, which has e.g. both in tune and in t`e hus.
Core eME: no dative marker for nouns - in tu__n
-
accusative form for indefinite article
This is observed inconsistently in Orm, which has both an and aenne for the accusative, e.g. Illc mann an peninng m acc y%aefe but Y`e shulenn findenn aenne child nt acc. PC2 displays only an for the accusative.
Core eME: no separate accusative form for a__n
-
dropping of unstressed penultimate syllable in inflected forms of nouns and adjectives
This is a feature of OE. Unstressed penultimate syllables were often dropped in the inflected forms of nouns and adjectives before n, r and l, e.g. OE dryhten/dryhtnes, mic`el/micle. According to Wright 2, the unstressed vowel "regularly disappeared in open syllables when the stem syllable was long", though fugol, with short stem vowel, was one of a group declined like engel engles 3. The syncope can still be found in Orm - deofell/deofless, mikkell/miccle, and in PC2 - od`er/od`re, castel/castles, minster/minstre, gysles. On the other hand, we see PC1 fugeles, PC2 drihtines, micele, AW deoueles, fuheles, and Lmn & Owl fuy`eles, to give just a few examples.
Core eME: the unstressed penultimate syllable is retained in inflected forms of nouns and adjectives - casteles, de__feles, drihtenes, fugeles, micele, minstere, o__t`ere, y%i__seles etc
-
genitive forms without the -(e)s marker
This is a relic of two different OE noun classes - the feminine o_-stems of the strong declension, in which the genitive marker was a final e, e.g. sa_wol sa_wle, and the stems in -r of the minor declension, in which a genitive marker was absent, e.g. mo_dor mo_dor, and similarly for faeder, bro_d`or, dohtor, sweostor. The former is observed inconsistently in Orm, which has both sawle and sawless for the genitive.
For the reflexes of the stems in -r, we need to enlist principles 3 & 4. Against Orm's moderr, brot`err (gen) we can counterbalance moderes (Genesis and Exodus 1250) and faderes (Poema Morale 1175).
Ch has an occasional "zero" marker for the genitive in reflexes of a couple of OE weak declension nouns: hlae_fdig`e hlae_fdig`an, heorte heortan > lady lady, herte herte. Orm on the other hand, consistently has he(o)rrtess as the genitive.
Core eME: all genitive forms have the -(e)s marker
Levelling underway in all pre-1250 sources
This section includes not only pre-1250 sources found in the MED, but also variant OE forms. The pre-1250 MED sources include PC2 and Orm as well as the secondary eME sources - Lmn, AW and Owl.
-
stem alternation (with or without <w>) in reflexes of wa- and wo_-stems
In OE feminine wo_-stems, a <w> appears at the end of the stem, before the case marker, throughout the paradigm, except in the nominative singular, which has a final <u>, or less often - no final vowel. The wa_-stems behave similarly, but with the expected differences characteristic of masculine and neuter strong noun declensions.
It's interesting to note that of the wa- and wo_-stem nouns that have survived to ModE, the reflexes of feminine mouns tend to retain the <w> - sinew, shadow, meadow, leasow (pasture), while the reflexes of neuter nouns do not - meal, smear, bale (harm). This is not surprising, since in the OE neuter nouns, four case forms - the nominative and accusative, both singular and plural, had no <w> in the stem, while for the feminine, only the nominative singular lacked the <w>.
Clark Hall 4 and the MED provide the following examples of levelling within paradigms, either with or without <w>, in texts dated before 1250:
- neuter wa- stems - genitive or dative without <w>: 1211 smeres gen, Orm tre dat, AW leohe dat, 1250 ter dat; plural in -es without <w>: 1250 bales, Orm cnes, tres, 1225 knes;
- masculine wa-stems - nominative or accusative sg with <w>: 1197 barewe (grove), 1242 berwe, Orm t`eww
- feminine wo-stems - nominative sg, with <w> - AW schadewe, TH 1200 shadewe, 1225 scadewe, 1250 schadwe, OE alt mae_dwa m sg; [and possiby: 1240 Hardemedwe (name), 1236 Smythesleswe (name)]
Core eME: no stem alternation in the reflexes of wa- and wo_-stems - bale bales, smere smeres, tere teres, barew barewes, tre__ tre__s, cne__ cne__s, le__ le__s, t`ew t`ewes, scadew scadewes, maedew maedewes, laesew laesewes
See simplification of OE noun paradigms: wa- and wo-stems for more detail.
-
stem alternation (with or without <h>) in reflexes of a-stems with final <h>
In OE masculine a-stems with final <h>, the <h> appears at the end of the stem in the nominative and accusative singular only. Throughout the rest of the paradigm, the <h> is missing and the preceding vowel, if short, is lengthened.
Clark Hall 4 and the MED provide the following examples of levelling within paradigms, either with or without <h/g/y%>, in texts dated before 1250:
- nom/acc sg without <h>: OE alt we_al, wal-, 1225 wale; OE alt mear, AW meare, 1200 mare; OE alt seol; OE alt fe_or, 1150 PA fere acc; OE alt fe_o, Lmn feo; OE alt sco_, Orm sho, 1200 TH sho;
- oblique forms (gen/dat/pl) with <h/g/y%>: OE alt slo_ges gen; OE alt wo_ges gen, wo_ge dat, Orm woy%h`e dat, PC1 woge dat, Lmn woy`e dat, AW wohe dat, Owl woy`e dat, 1200 wohy`e dat; OE alt eolc, eolces gen; OE alt salhas pl, saligum pl dat.
Core eME: no stem alternation in the reflexes of a-stems with final <h> - wale wales, mare mares, fere feres, fe__ fe__s, sco__ sco__s, slo__h slo__ges, wo__h wo__ges, elk elkes, salh salges, sele seles, halh halges, farh farges, alh alges, eh eges, horh horges
See simplification of OE noun paradigms: a-stem nouns ending in <h> for more detail.

bicy%en and biy%en
byc`g`an, meaning to buy, is the standard OE form according to Clark Hall 1, which gives us the eME form bicy%en (/dZ`/). Since Orm has biggenn (/dZ`/) and both AW and Owl have buggen (/bydZ`/) and PC2 has no competing form, an additional eME form doesn't appear to be an option. Note that in the OE paradigm, the 1st person singular and 3rd person plural of the present forms have a different stem to the 2nd and 3rd person singular - byc`g`e byc`g`at` vs byg`st byg`t`. This would pass to eME as bicy%e biy%est biy%eth bicy%en. Ch on the other hand has no such alternation between 3rd person singular and plural - byeth byen. But Ch comes a little too late. What we need is that loss of stem alternation prior to 1250, if not in bicy%en, then in similar verbs which had c`g`/g` stem alternation in OE, and have survived to ModE. And we have that with PC2 saein, lien inf, 1175 leged` pr pl and 1200 leiy`en inf (ModE say, lie, lay). Thus there is a clear pattern here, which we can extend courtesy of principle 4. We can be reasonably confident that if say%en, liy%en and ley%en were spoken by East Midlanders around the year 1200, then the same applies to other verbs with a similar stem alternation, e.g. biy%en, friy%en, t`iy%en. Thus biy`en, although not an additional eME form (via principle 2), passes to the core grammar via principle 4. For more detail, see gemination in eME.

Notes
- in one exceptional case, Ch and ModE aren't in accord: Ch has both stree and straw sg and stres pl while ModE has only forms with w - straw sg and straws pl; I've listed strawe as the preferred form in eME
- h never survives to ModE in the reflexes of words with stem alternation in OE
