Craic (/kræk/ KRAK) or crack is a term for news, gossip, fun, entertainment, and enjoyable conversation, particularly prominent in Ireland.[1][2][3] It is often used with the definite article – the craic[1] – as in the expression "What's the craic?", meaning "How are you?" or "What's happening?". The Scots and English crack was borrowed into Irish as craic in the mid-20th century and the Irish spelling was then reborrowed into English.[1] Under both spellings, the term has become popular and significant in Ireland.
