While adjectives seldom follow full nouns, they often follow indefinite pronoun, despite the fact that adjectives

rarely precede pronouns of any sort.

eg. Nobody new has joined the sorority.
     Someone tall snatched the oranges from the tree.
     Nothing bad happened at the meeting.

Prepositional phrases frequently function as postnominal modifiers, usually following full NPs.

The little girl in the blue dress is my niece.
