Etymology

The word "laughter" originates from Old English hleahtor, derived from the Proto-Germanic hlahtraz, which is tied to the verb "laugh." The root hleh- (to laugh) is imitative, reflecting the sound of laughter itself. Over time, the suffix -ter (or -tor in Old English) was added to form a noun denoting the action or result of laughing. This evolution highlights how laughter is both a vocal expression and an abstract concept tied to joy.
