disc▪ This value of √ZWR is neither mentioned in DRS nor in Militarev&Kogan2000, obviously because it does not have a Sem dimension.
▪ Nevertheless, Dolgopolsky2012#2753 tentatively, though not without marking the operation as doubtful, suggests to link Ar zawr ‘chest’ to words for ‘heart’ in Turk langs (e.g., Tu yürek < oTu jüräk). He reconstructs Sem *zawr- and Turk *jür-äk (< Alt *ǯür˅k‘˅ ‘heart’, × Nostr *dür˅ ¬ *dUrE ‘entrails, heart’), and, on this basis, proposes a shared origin in Nostr *ʒ̍ûr˅ ‘inside of body’.
▪ Some ClassAr lexicographers regard zawr as the etymon of the vb. ↗zāra ‘to visit’, interpreting the latter as *‘to meet s.o. with one’s zawr (chest, bosom)’ or ‘to repair to s.o.’s zawr (i.e., direction)’; hence, in ClassAr, zawr is also used in a fig. sense, as the ‘direction of a person to whom one repairs’ (Lane).
▪ To zawr in the sense of ‘upper part of the chest; throat’ belong probably also the obsol. nouns †zāraẗ, zāwiraẗ, and zāwūraẗ, all meaning ‘bird’s crop’.
▪ An item that is interesting because it may link zawr ‘upper part of the chest’ to ↗zawar ‘to turn aside, be crooked, be distorted’, is the obsol. intr. vb. I, †zawira ‘to have a distorted zawr ’; cf. also †zawr ‘camel having the hump inclining’ (Lane).
▪ In ClassAr, zawr can take a number of other meanings, such as †‘intellect; [? hence:] resoluteness, (strength of) determination’, hence (?) also †‘master, lord, chief, leader’ (var. zūr, ziwar); †‘stone which appears to a person digging a well, and which, being unable to break it, he leaves apparent; a mass of rock’ (Lane); †‘(straight and slender) palm-branch from which the leaves have been stripped off’; †‘phantom in sleep’ (DRS #ZW/YR-1g). A relation between these items and zawr ‘upper part of the chest’ does not seem to be likely, although the etymologies of most of them are obscure. Only zawr in the sense of †‘phantom in sleep’ is probably literally *‘s.th. that visits you while you are asleep, dreaming’, which would make it dependent on ↗zāra ‘to visit’, not zawr ‘chest’.
▪ Any connections with ↗zūr_1 ‘lie, untruth, falsehood’ ?
