declension

This term describes the mechanical shifting of a word's ending to signal its role in a sentence. It is a technical linguistic tool used to track who is doing what to whom without relying solely on word order. It evokes a sense of structured, mathematical precision in language architecture. In modern English, declension is largely vestigial, appearing mostly in pronouns like he versus him. In contrast, highly inflected languages use declension as a primary map for meaning, making the word's form more important than its position in the phrase.
