Gloss: ‘pear’ (item 25 in Bjørn 2017)
(?)Alb. dardhë; Gr. ἂχεδρος ‘wild p.’, ἀχράς ‘id.’; Mac. ἀγέρδα ‘id.’
Limited distribution to a very compact geographical region, the Balkan, has very weak bearings on PIE etymology, even more so if Orel’s reservations on Albanian are heeded (1998: 56). Furnée considers it a particular pre-Greek substrate word (1972 :127).
NW Caucasian: *q(w)a
NE Caucasian: *qcör (Dolgopolsky 1989: 15)
Kartvelian: *msxal– (Fähnrich 2007: 296f.)
Nikolayev & Starostin, scrutinizing the North Caucasian connections, further compare the Kartvelian forms, although they concede the formal difficulties the inclusion entails (NCED s.v. ‘pear’). The linguistic travels of the fruit may be compared to that of the apple (item 42) that nonetheless appear to have wider distribution within IE. If connected, Dolgopolsky’s suggestion of a loan from North Caucasian *qcōrV (NCED *qHǖre, s.v.) or one of its descendants into a dialectically diversifying PIE (1989: 15) best fit the picture (cf. also S. Starostin 2009: 88f.), although the geographic discontinuity poses a serious obstacle (cf. Matasović 2012: 290). Caucasian connections for the Balkan languages are also pertinent in the discussion of *ĝhor-io- ‘pig’ (item 18).
