Inflexie

Inflexie is the term used in Dutch linguistics to describe inflection, the modification of a word to express grammatical information such as tense, number, person, mood, voice, case, or aspect. These modifications are achieved through inflectional forms, produced by affixes, internal vowel changes, or other alternations, and are organized in inflectional paradigms.

In languages with rich morphology, inflection affects multiple word classes, including verbs, nouns, adjectives, and pronouns. For example, in English, verbs inflect for tense and agreement (walk, walks, walked; she walks), and nouns inflect for number (cat, cats). In other languages, such as Latin or Russian, inflection has more extensive case and agreement systems, affecting nouns, adjectives, pronouns, and verbs, shaping the word's form according to syntactic role and grammatical categories.

Inflexion is typically contrasted with derivation, where forms change to create new words with new meanings (happy vs happiness) rather than merely altering grammatical function. Some languages rely more on word order and auxiliaries than on inflection, while others encode most grammar in inflected forms.

The term inflexie derives from Latin inflexio and is standard in Dutch grammatical terminology. It is closely related to related concepts such as declension (noun/adjective inflection patterns) and conjugation (verb inflection patterns). The study of inflexie intersects with morphology, syntax, and typology, illustrating how languages encode grammatical relations in different morphological systems.
