What is Preposition?
Prepositions and postpositions, collectively referred to as adpositions, are a collection of words used to designate distinct semantic functions or describe geographical or temporal links (in, beneath, towards, before). Its complement, or occasionally object, is the noun phrase that a preposition or postposition usually joins with. A postposition comes after its complement whereas a preposition comes before it. Prepositions rather than postpositions are more common in English; for example, in England, under the table, and of Jane all come before their respective objects. However, there are a few exceptions, such as "ago" and "notwithstanding," as in "three days ago" and "financial limitations notwithstanding." Postpositions or both types are used in several languages with a distinct word order.
