<h3>What is a prepositional?</h3>
Prepositions and postpositions, collectively known as adpositions (or, more generally, prepositions in classical grammar), are a class of words used to indicate various semantic obligations as well as to transmit spatial or temporal relationships (in, under, towards, or before) (of, for).
The preposition or postposition's complement, or occasionally object, is the union of a preposition or postposition and a noun phrase. A preposition comes before its complement, whereas a postposition comes after. English frequently utilizes prepositions rather than postpositions, with a few exceptions like "ago" and "notwithstanding," as in "three days ago." Like in England, under the table, and of Jane, words like in, under, and of come before their respective subjects.
