cheer

The word "cheer" entered English in the late 13th century from the Anglo-Norman chere, meaning "face, countenance, or expression." This, in turn, derived from the Late Latin cara, for "face," which came from the Greek kárā, signifying "head." The semantic evolution is a fascinating journey from the concrete to the abstract: from "face," the meaning broadened to "mood" or "state of mind as shown by the face" (hence "good cheer" meaning a happy disposition). By the late 14th century, it developed the sense of a shout or cry to encourage or applaud, likely because such shouts were expressions of a supportive mood or spirit. Thus, the modern meanings of a shout of encouragement and a feeling of happiness both flow logically from this ancient root related to facial expression and mood.

The word "cheer" is a simplex word of Anglo-Norman origin. It cannot be meaningfully segmented into smaller, independent morphemes within its modern English spelling.
