PROTO: *χ_wārē / *rāχ_wē
MEANING: a k. of foliage tree
COMMENT: Reconstructed for the PEC level. An interesting root, denoting originally a lime-tree (or a similar foliage tree), which was used for construction (cf. the construction terms in Lezghian languages). We can reconstruct the old direct base as *χ_wārē, and the oblique one - *χ_wōrV- (cf. the situation in PL and possibly PD). In spite of the metathesis in Gunz. (possibly conditioned by analogy with *rä̆śwē 'tree, wood' q.v. and some other tree-names), the etymology seems quite plausible.
