Answer 2

of. Postpositions and prepositions are known as adpositions. In general English, they are called as prepositions.

They are a class of words that are used to express temporal or spatial relations (e.g., under, before, towards, in, etc.) or to mark different semantic roles.

A postposition or preposition generally mixes with a noun or pronoun, or more usually with a noun phrase. It is known as its complement or sometimes the object.

A preposition usually comes before the complement whereas, a postposition is added after a complement.
