What are Prepositions?

Prepositions are the part of English grammar which are used to indicate relationships between words within a sentence. Prepositions play different roles; in addition of linking nouns, pronouns or other words, propositions can help you talk about a certain period of time, or express a position, direction or location.

Types of prepositions:

Generally, we can separate propositions into three types:

  • Preposition of time is a preposition which allows you to talk about a certain period of time. They are often used in situations in which it’s important to indicate that something takes place at a specific time.
  • Proposition of place is a preposition that is used to indicate place of something or expressing a location. There is a set of different propositions of place which can be used in multiples contexts.
