a substantial number don't have convincing etymologies or do not constitute isoglosses between Balto-Slavic and Albanian. An example is Albanian murg (dark) and Lithuanian margas (colourful) which Orel considers to be isoglosses but both are equally related to Proto-Germanic *murkaz, ancient Greek amorvos and Proto-Slavic *mergъ. Orel identifies only one Albanian/Italic/Celtic isogloss, blertë ("green"), cognate to Latin flōrus ("bright") and Irish blár ("gray"). Specifically Celtic/Albanian vocabulary was previously thought to be limited although including at least one core vocabulary item (hënë "moon", cognate to Welsh cann "white" and Breton cann "full moon"), but recent work by Trumper in 2018 has proposed a larger though still not overwhelming set, with the notable addition of dritë ("light"). Although knowledge of Tocharian is fragmentary, the one known Albanian/Tocharian isogloss is "very important" as noted by Orel: kush ("who", cognate to Tocharian A kus, with the same meaning).
