"Kebab" syftar inte på själva köttet, utan på rätten:
"Kebab (also occasionally transliterated as kebap, kabab, kebob, kabob, kibob, kebhav, kephav) refers to a variety of meat dishes in Persian, Turkish, Caucasian, Israeli, Central Asian, South Asian and some of the African cuisines, consisting of grilled or broiled meats wrapped in bread accompanied by lettuce and tomatoes with garlic sauce.
The most common kebabs include lamb and beef, although others use goat, chicken, fish, or shellfish."

Just rätten man får när man går till en pizzeria och beställer Kebab heter Döner Kebab, och köttet där är i regel nöt.
