Comments:Cf. Bur. jogšo- 'to ache, nag'. Turk. *īg is perhaps a result of secondary narrowing < *(i)ēg. In TM there exists also an apparent derivative *iagsi- 'to sneeze' which is very similar to PT *aksɨr- (*agsɨr-) id. (see ЭСТЯ 1, 194-195). This may be either an old derivative, phonetically distorted in Turkic, or an independent onomatopoeic root.
