Preposition

In grammar, a preposition is a type of adposition, a grammatical particle that establishes a relationship between an object (usually a noun phrase) and some other part of the sentence, often expressing a location in place or time.

Notes

• Historically, English was in fact an inflected language, relying on cases instead of word order to convey grammatical information. Thus English had a much smaller number of prepositions in its lexicon. However, as Old English evolved into Middle English into Modern English, inflections were dropped in favor of word order, and many new prepositions were added.
