Pantomime (informally, panto) – not to be confused with the theatrical medium of mime – is a musical-comedy theatrical production traditionally performed in the United Kingdom, Australia, New Zealand, Canada, Zimbabwe, Jamaica, South Africa, India, Ireland, Gibraltar, and Malta, mostly during the Christmas and New Year season. The word derives from the Greek "παντόμιμος" (pantomimos), "pantomimic actor" and from "παντός" (pantos), genitive of "πᾶς" (pas), "every, all" + "μῖμος" (mimos), "imitator, actor".
