Preposition Definition
A preposition is a word that tells you how words are related in a sentence. It could often follow a verb, but it does not always. The example of the frog and a log can tell you a lot of them, but those are only one of two categories of prepositions.
In fact, there are two types of prepositions: ones that tell about the place and ones that tell about time and time order.
