Postpositive adjective
A postpositive or postnominal adjective is an attributive adjective that is placed after the noun or pronoun that it modifies. This contrasts with prepositive adjectives, which come before the noun or pronoun.
In some languages (such as French, Spanish, Italian and Romanian) the postpositive placement of adjectives is the normal syntax, but in English it is less usual, largely confined to archaic and poetic uses (as in They heard creatures unseen), certain traditional phrases (such as heir apparent), and certain particular grammatical constructions (as in those anxious to leave).
