Word Building - derivation

from adjectives

§141

I.B.a.- NOUNS are derived FROM ADJECTIVES by means of the suffixes listed below. On adjectives used as pronouns or nouns, see §40-§41 above.

-essa
'state or quality of being ...' e.g.
polite > politessa 'politeness'; ric 'rich' > ricchessa 'wealth';
new formation: apte 'apt' > aptessa 'aptitude'
-ia
(pron '-ia) 'state or quality of being ...' e.g.
efficace 'effective' > efficacia 'effectiveness';
new formation: felice 'happy' > felicia 'happiness'; fraudulente 'fraudulent' > fraudulentia 'fraudulence'
Note: Used chiefly with adjectives in -nte. The combination -ntia coincides with the postverbal noun suffix -ntia. See §148 under -antia.
-ia
(pron -'ia) 'state or quality of being ...' e.g.
zelose 'jealous' > zelosia 'jealousy';
new formation: brachycephale 'brachyeephalic' > brachycephalia 'brachycephalism'
Note: Used chiefly with technical compounds.
-ismo
  1. 'state or quality of being ...' e.g.
    provincial > provincialismo 'provincialism';
    new formation: brutal > brutalismo 'brutality';
  2. 'doctrine or practice concerned with what is ...' e.g.
    social > socialismo 'socialism';
    new formation: atonal [Mus.] > atonalismo [Mus.] 'atonalism';
  3. 'something characteristic of the... people or of their language' e.g.
    german 'German' > germanismo 'Germanism';
    new formation: polynesian 'Polynesian' > polynesianismo 'Polynesianism'
    Note: For derivatives from nouns, see §138.
-ista
'adherent of the doctrine or practice concerned with what is ...' e.g.
social > socialista 'socialist';
new formation: atonal [Mus.] > atonalista [Mus.] 'adherent of atonalism'
Note: For derivatives from nouns, see §138.
-itate
'state or quality of being ...' e.g.
regular > regularitate 'regularity';
new formation: cohesive > cohesivitate 'cohesiveness'
Note: Synonym of -itude, but preferred when the base is already a derivative. In further derivation (not recommended for active use), -itate appears as -it- before suffixes beginning with a; e.g.
autoritate 'authority' plus -ari > autoritari 'authoritarian.'
-itude
'state or quality of being ...' e.g.
certe 'certain' > certitude 'certainty';
new formation: emerite 'emeritus' > emeritude 'emeritus status'
Note: Synonym of -itate. Extended to -itudin- in further derivation; e.g.
latitude latitudinal.

§142

I.B.b.- The active derivation of ADJECTIVES FROM ADJECTIVES is limited to the use of one diminutive suffix and the formation of absolute superlatives in -issime treated in §36 above. Note that every noun in -ista can function as an adjective. e.g. socialista 'socialist, socialistic.'

-ette
'somewhat..., pretty ...' e.g.
belle 'beautiful' > bellette 'pretty';
new formation: blanc 'white' > blanchette 'whitish'

§143

I.B.c.- On the formation of DERIVED ADVERBS see §45-§47 above.

§144

I.B.d.- The derivation of VERBS FROM ADJECTIVES runs completely parallel to that of verbs from nouns. See §140 above.
