In Azerbaijani, non-initial /-g-/ has evolved to /-j-/, whereas in Turkish it has evolved to /-v-/, compare Turkish dövmek vs. Azerbaijani döymək, both from Old Anatolian Turkish [script needed] (dögmek, “to beat”); Turkish sövmek vs. Azerbaiani söymək, both from Old Anatolian Turkish [script needed] (sögmek, “to swear”). Turkish üvey (“step-”) therefore demonstrates a regular phonological development, while the Azerbaijani term unexpectedly preserves the intervocalic /-g-/ instead of the expected /-j-/, which would yield *öyey.
- step-; a prefix used before father, mother, brother, sister, son, daughter, child, and so forth, to indicate that the person being identified is not a blood relative but is related through the marriage of a parent.
