Odmiennoci

Odmiennoci is a linguistic term used to describe the system of inflectional endings that mark grammatical categories in a language. It refers to how words change form to reflect features such as case, number, gender, and sometimes mood or tense. In languages with a robust odmiennoci, these endings attach to stems and create predictable patterns known as paradigms or declensions for nouns, adjectives, and verbs.

The concept is closely linked to morphology and is often discussed in contrast to fixed word order, where grammatical relations are conveyed primarily by sentence structure rather than inflection. Odmiennoci encompasses noun declensions, adjective agreement, and verb conjugations, with endings that vary depending on grammatical role, number (singular, plural), and sometimes other categories such as definiteness or aspect. Some languages also exhibit stem changes, vowel alternations, or consonant mutations as part of their odmiennoci.

Terminology usage varies by linguistic tradition. In some contexts, odmiennoci is described as the organized system of inflectional endings that signals how a word functions within a sentence, rather than as a separate set of words. Because the term is not universally standardized across grammars, it is most often encountered in discussions focused on inflection and morphology rather than in general grammar guides.
