Prepositions are words that show the relationship of nouns or pronouns to other words in the sentence. The relationship can be spatial (where something is), temporal (when something is) or motive (the manner or direction of movement). Prepositions are placed before nouns or the determiner preceding the noun. Below is a list of the more commonly used preposition.
Prepositions of Time
about around after at by
during for from since until
The bananas are in the refrigerator.
Prepositions of Place

inside off on next to under

Prepositions of Movement

Prepositions create many problems for non-native speakers because many times their use does not follow any rules that learners can utilize to master them. They may be specific to the words around them or referred to. For example:
We watch movies in a theater, but on TV.
We visit friends at the hospital, because they are in the hospital.
