The Iranian polymath Bīrūnī (973–1048) in his work al-Ṣaydana fī al-Ṭibb, mentions the Kurdish word (kurdī) for the storax tree (Arabic lubnā), which produces a fragrant benzoin resin:
“The tree is named lubnā, but the substance that flows from it is called mayʿa, and in Kurdish it is called kinār.”
I'm not a linguist, but I wonder if kinār (modern Kd. kinēr) is related to Persian kondor “frankincense.”
