A preposition is a word placed before a Noun or Pronoun to show its relation to some other word in the sentence. Prepositions are normally placed before nouns or pronouns. The points below explain more about prepositions.
At, in, on, off, below, through, with. are some of the prepositions.
The Noun or Pronoun used with the preposition is in the accusative case. (e.g: I did not talk to her)
Adverbs of time and place can also be the object of preposition. (e.g: He had returned by then.)
A clause can also be the object to a preposition. (e.g: Pay attention to what your teachers say.)
A preposition sometimes may have more than one object. (e.g: Distribute the mangoes among the girls and boys.)
When verbs are placed after preposition they should be in the Gerund form except when they are used in infinitive form. (e.g: I would like to help him.)
