  • From the Gaelic craic (I think), for "fun."

  • I think its usage as a noun, e.g. "how's the crack?", does indeed derive from craic. But adjectival use, such as "our crack forensic pathologist" seems likely to have a different etymology (e.g. from crackerjack, perhaps?).

  • Well, yeah. I just meant in the sense of "fun."

    OED says the 16th definition of crack is the connotation in question here: "That which is the subject of boast or eulogy; that which is ‘cracked up’; a horse, player, ship, regiment, etc. of superior excellence..." The first usage in this sense is listed as being in 1637. Unfortunately it doesn't list an etymological source. Hmm.
