laugher

The word 'laugher' is a transparent agent noun formation from the Middle English verb 'laughen', which itself evolved from the Old English 'hlæhhan'. The agent suffix '-er', of ancient Germanic pedigree, is one of the most productive in English, routinely attached to verbs to denote 'one who does' (e.g., runner, writer, teacher). Literally, a 'laugher' is 'one who laughs'. Its secondary meaning, denoting something that provokes laughter, represents a subtle semantic shift where the agent suffix '-er' applies figuratively to the cause of the action rather than the performer, a pattern also seen in words like 'thriller' (something that thrills). The core concept connects directly to the universal, instinctive physical expression of amusement or joy.
