Preposition has two definitions: (1) a word or phrase used to relate a noun or pronoun grammatically to another part of the sentence, and (2) to position in advance. Proposition means (1) a plan or offer suggested for acceptance, (2) a matter to be dealt with, and (3) to propose a private bargain. The two are occasionally confused—for example:
