ADJECTIVES are derived FROM NOUNS by means of the suffixes listed below. On the use of nouns in apposition with quasi-adjectival functions, see §30 above.
-al
'pertaining to ..., characteristic of ..., etc.' e.g.
natura 'nature' > natural;
new formation:veneno 'poison' > venenal 'poison, of poison'
Note: The most general and unspecific adjectival suffix. The variant -ar is to be preferred with nouns containing l; e.g.
bussola 'compass' > bussolar '(of the) compass.' The type interrogatorial may be construed as a derivative from interrogatorio 'interrogatory' or (with the suffix variant -ial) from interrogator. In patterns of this sort the variant -ial is to be preferred.
-an
'pertaining to ...'; esp. 'native of ...' e.g.
urbe 'town' > urban; Mohammed > mohammedan 'Mohammedan'; Africa > african 'African';
new formations:Tolstoi > tolstoian 'Tolstoyan'; Asia > asian 'Asian'
Note: Used with names of places and persons. In the case of place names not ending in -a or -o as also of all names of persons, the euphonic variant -ian is to be preferred; e.g.
Zamenhof > zamenhofian 'Zamenhofian'; but also Canada > canadian. The corresponding noun form is -ano (-iano).
-ari
'pertaining to ... , consisting of ... , etc.' e.g.
legenda 'legend' > legendari, 'legendary'; fragmento 'fragment' > fragmentari 'fragmentary';
new formation:vestimento 'garment' > vestimentari 'garment'
Note: Functions as adjective corresponding to nouns in -ario, -ero and -iero. The variants -er and -ier may be used to correspond to nouns in -ero and -iero respectively.
Note: Coincides with past participle, in adjectival use, of verbs in -ar; e.g.
anellar 'to ring' > anellate 'ringed.'
-esc
'like, similar to, or characteristic of a ...' e.g. gigante 'giant' > gigantesc 'gigantic'; new formation:elephante 'elephant' > elephantesc 'elephantlike';
