adpositsioonid

Adpositsioonid are a class of function words that express a relationship between a noun phrase and another element in a clause. They include prepositions, postpositions, and circumpositions. A preposition precedes its complement, a postposition follows it, and a circumposition consists of material placed both before and after the complement.

These elements typically govern a complement noun phrase and mark spatial, temporal, or other relations. Common semantic domains expressed by adpositsioonid are location (inside, over), direction and path (into, toward), time (before, during), source and goal (from, to), possession, instrument, and manner. The exact set of adpositions and their meanings varies across languages, and many languages encode some of these relations through case or verb morphology rather than separate adpositions.

In syntax, adpositional phrases (the phrases headed by adpositsioonid) function as adjuncts or, in some languages, as arguments of verbs and other predicates. They can determine the case form of the noun phrase they link with, influence pronoun forms, and interact with word order to convey nuances of meaning. Some languages rely heavily on adpositions, while others rely more on inflectional case to express similar relations; many languages use a combination of both strategies.

Typologically, adpositsioonid are part of a broader adpositional system that includes prepositions, postpositions, and circumpositions. They play a central role in expressing spatial and temporal relations and often interact with the morphological structure of the noun phrase, contributing to the overall flexibility and expressiveness of a language.
