This is a list of English prepositions. In English, some prepositions are short, typically containing five letters or fewer. There are, however, a significant number of multi-word prepositions. Throughout the history of the English language, new prepositions have come into use, old ones fallen out of use, and the meaning of existing prepositions changed. Nonetheless, the prepositions are by and large a closed class.
