bıç-/biç-
‘to cut’; one of several words with this meaning, cf. üz-, kes-, etc., with restricted meanings like ‘to cut out (a garment)’ in some modern languages. The original form was almost certainly bıç-, but there is great inconsistency about the vocalization, some modern languages having a back vowel in the verb and a front one in der. f.s like bıçak or vice versa. Survives with back vowel in NE and NC Kır. and front vowel in NW, SW; in SE, SC where -ı- does not occur the true form is uncertain.
