Terms Relating to Adjectives
Many adjectives can be used attributively, i.e. come before the noun they modify, e.g. certain in a certain man (not the man is certain, which means something very different), and/or predicatively, i.e. come after the verb, e.g. ajar in the door was ajar (not the ajar door).
Some adjectives can be used postpositively, i.e. they typically come immediately after the noun which they modify, e.g. galore in there were prizes galore (not there were galore prizes). While attributive use is standard for most adjectives, especially those in specialist or technical fields, postpositive use is unusual in English and generally arises because the adjective has been adopted from a language where postpositive use is standard.
