1. An Attributive Adjective simply qualifies its noun without the intervention of a verb or participle, expressed or implied: as, —bonus imperātor, a good commander; stellae lūcidae, bright stars; verbum Graecum, a Greek word.
2. All other adjectives are called Predicate Adjectives:—

1. stellae lūcidaeerant, the stars were bright.
2. “sit Scīpiō clārus” (Cat. 4.21) , let Scipio be illustrious.
3. “hominēsmītīs reddidit ” (Inv. 1.2) , has rendered men mild.
4. “tria praedia Capitōnīpropria trāduntur ” (Rosc. Am. 21) , three farms are handed over to Capito as his own.
5. cōnsilium cēpēruntplēnum sceleris (id. 28), they formed a plan full of villany.

[*] Note.--A predicate adjective may be used with sum or a copulative verb (§ 283); it may have the construction of a predicate accusative after a verb of naming, calling, or the like (§ 393. N.); or it may be used in apposition like a noun (§ 282. b).
