A word from Marain, a made-up language invented by Iain Banks for his society the Culture.

The word's meaning is "gambler" - it's suggested to Gernau Morat Gurgeh in "The Player Of Games" as a better alternative to "Morat" for the chosen word in his name, as he is more of a gambler than a "player of games" (Culture names are very long and complicated, "Gernau Morat Gurgeh" is a shortened form of his name)
