Prepositions

A preposition is a word or group of words used to link nouns, pronouns and phrases to other words in a sentence. Some examples of prepositions are single words like in, at, on, of, to, by and with or phrases such as in front of, next to, instead of. Prepositions in English are most frequently dictated by fixed expressions. While there are some general guidelines to follow, many prepositions are used idiomatically with certain verbs. In these cases, it is best to memorize the phrase instead of the individual preposition.
