The word **期末** is a compound noun formed by combining two meaningful characters: **期** (qī), meaning "a fixed period," "term," or "scheduled time," and **末** (mò), meaning "end," "tip," or "final part." Morphologically, it is a **modifier-head** or **endocentric** compound where **末** ("end") is the semantic core, and **期** ("term") modifies and specifies it, creating the combined meaning "the end of a term." This logical and common structure in Chinese word formation efficiently conveys the specific concept of the conclusion of an academic, financial, or project-based period.
