kula

accusative singular of kul

slave (sense as a noun mostly archaic, except "kul köle" and similar idioms - even figuratively, where "köle" is commoner. An exception is the verb form "kulluk yapmak, "to serve" in pejorative sense)
servant
position of man according to God (No equivalent, even in "servant" of the lord this sense is preserved. In this context "mortal" sense in vernacular is understood, versus an "immortal god")
