ḳáynəˀ - to be jealous (ML 232)

PWS
*ḳnˀ - to be jealous (Kogan 2015: 88)
Possible attestations of this root in Arabic are problematic. Many scholars accepted its connection with Arb. qnˀ ‘to be intensely red’, very tentatively mentioned in Brockelmann 1932:115, but this is semantically rather far-fetched. Perhaps more promising as a cognate would be Arb. qnˀ ‘to incite, to induce to kill someone’ = “to kill out of envy”?
