Preposition
Part of speech: verb
Definition: To place in a location before some other event occurs.
Part of speech: noun
Definition: A closed class of non-inflecting words typically employed to connect a noun or a pronoun, in an adjectival or adverbial sense, with some other word; a particle used with a noun or pronoun (in English always in the objective case) to make a phrase limiting some other word; — so called because it is usually placed before the word with which it is phrased, as in a bridge of iron; he comes from town; it is good for food; he escaped by running. Prepositions are a heterogeneous class of words in some languages, with fuzzy boundaries that tend to overlap with other categories (like adverbs, adjectives, and conjunctions) and also allow for inflected prepositions. Prepositions can be distinguished from adverbs by close examination of the sentence: if the verb is not modified directly, the word is likely a preposition. He jumped fast shows the adverb fast, while in he jumped over, over is a preposition because it implies jumping over something. A proposition; an exposition; a discourse.
