There are about 150 prepositions in English. Yet this is a very small number when you think of the thousands of other words (nouns, verbs etc). Prepositions are important words. We use individual prepositions more frequently than other individual words. In fact, the prepositions of, to and in are among the ten most frequent words in English. Here is a short list of 70 of the more common one-word prepositions. Many of these prepositions have more than one meaning. Please refer to a dictionary for precise meaning and usage. You can also see the long preposition list with example sentences here.
I have been looking for such a concise list of prepositions for a long time. I tried even making my own, following whatever information I could gather from here and there. And then I came across this site and the list, of course. Thank you for making it available to us.
