A preposition typically combines with a noun or a pronoun. Prepositions usually come before a complement in a sentence. However, there is an exception to this role for the prepositions ‘ago’ and ‘notwithstanding’, which come after the compliment. Prepositions are of two types, they are

1. Prepositions of time
2. Prepositions of place

There are no rules to using a preposition. However, it is good to determine the type of preposition, as it helps in framing grammatically structured sentences.

Prepositions are words that denote the position, location, direction, and time that cannot be shown otherwise. The preposition types can be further categorized into specific units. While doing so, two prepositions significantly mention the time factor; Since and From.
