Mirth
noun /mɜːθ/ — Amusement expressed through laughter; literary joy
Definition
Amusement or laughter — specifically the kind that is shared and expressed, not merely felt. The old English word for the active, audible, communal form of joy.
Beyond the definition
Joy that makes sound. Mirth is what happens when happiness cannot stay inside — when it has to come out as laughter, as play, as the specific brightness of people who are genuinely amused together.
Origin & history
From Old English 'myrgð' (joy, pleasure, mirth) — related to 'merry'. One of the oldest English words for joy — it precedes most of the Latin-derived alternatives. 'Eat, drink, and be merry' is older English than 'be happy'.
