Corrigenda:
NECK (SW50). New:
1. qaf|ë,a. Loan < Balkan-Trk. kafa ‘back of head’ (with HU106, OR353; not in BO). Turkic kafa itself is presumably loan from Arabic qabba 'collar'.
2. zverk|u (< Pk1155-3F.u̯er-k), primarily rather ‘nape’, the back part of the neck, albeit in some dictionaries not distinguished from (1).  My new decision is based on a translation of the medical expression for nape, “nucha” as adjective “nuchal” into Albanian by “zverk, izverkut”. Assuming that people knowing this technical term, are educated enough to distinguish nape from neck.
