Bedouin (n.) Look up Bedouin at
"an Arab of the desert, one of the tribes of nomadic Arabs," c. 1400, from Old French bedüin (12c., Modern French bédouin), from colloquial Arabic badawin "desert-dwellers," plural of badawi, from badw "desert, camp." The Arabic plural suffix was mistaken for part of the word. A word from the Crusades, it probably was lost in English and then reborrowed from French c. 1600. As an adjective from 1844.
