inflexív

inflexív is a term used in linguistics to describe words that do not undergo inflectional changes. Inflection refers to the modification of a word's form to express grammatical information such as tense, number, gender, case, or mood. Words that are inflexív remain in a constant, unchanging form regardless of their grammatical function in a sentence.

Examples of inflexív words vary across languages. In English, adverbs like "very" or "always" are typically inflexív. Prepositions such as "on" or "in" also do not change their form. Some pronouns, like "I" when used as the subject, can be considered inflexív in the sense that they don't change for plurality, though they do change for case (e.g., "me"). Interjections like "ouch" are also inflexív.

The concept of inflexív is particularly relevant when discussing languages with rich inflectional systems, where many word classes are heavily inflected. In contrast, analytical languages, which rely more on word order and auxiliary words to convey grammatical meaning, tend to have a higher proportion of inflexív words. Understanding which words are inflexív helps in analyzing sentence structure and the grammatical behavior of different word classes within a language. The study of inflexív words contributes to the broader field of morphology, the study of word forms.
