deratiivse

Deratiivse is the genitive singular form of the Estonian adjective deratiivne, which translates as “derivational” or “derivative” in English. In linguistic usage, deratiivne refers to derivational morphology—the set of processes that form new words by attaching derivational affixes to a base, often changing word class or semantic category rather than merely marking grammatical features.

In Estonian linguistics, deratiivne describes forms and relationships created by derivation. Derivation is distinguished from inflection, which modifies a word to express grammatical information such as case, number, or tense without producing a new lexeme. The phrase deratiivse tähendusega, for example, uses the genitive form to indicate something has a derivational meaning or quality.

Derivation is a common word-formation mechanism across languages and is a central topic in morphology. In Estonian, derivational processes enable the creation of adjectives from nouns, nouns from verbs, and other word classes, contributing to a productive and flexible vocabulary. Derivational affixes and patterns vary by language and can affect meaning, grammatical category, or syntactic behavior of the derived word.
