adpositions (or broadly, in English, simply prepositions), are a class of words used to express spatial or temporal relations (in, under, towards, before) or mark various semantic roles (of, for)
Types of Adpositions
A adposition typically combines with a noun or pronoun, or more generally a noun phrase, this being called its complement, or sometimes object.
- a preposition comes before its complement
- a postposition comes after its complement
- a circumposition consists of two parts that appear on each side of the complement
- a ambiposition
- a inposition
- a interposition
