uninflected
No form variation
Uninflected describes a word form that lacks the grammatical modifications—such as endings for tense, number, case, or gender—that many languages use to signal relationships between words.
In English, uninflected forms include base verbs like run or think before conjugation, and nouns before pluralization.
Some languages have largely uninflected vocabularies, relying on word order and context rather than morphological changes to convey meaning.
