odalisque (n.)

"female slave or concubine in a harem," 1680s, from French odalisque (1660s), from Turkish odaliq "maidservant," from odah "room in a harem," literally "chamber, hall," + -liq, suffix expressing function. In French, the suffix was confused with -isque, which is ultimately from Greek -isk(os) "of the nature of, belonging to."
