Reconstruction:Proto-Slavic/avorъ

Etymology
Rather unlikely from intermediary *āorъ, having been borrowed from, particularly from a late form without intervocalic [h]. Otherwise, maybe from the same European after the underlying language underwent a sound change from [k] to [v] or a sound shift of comparable consonants. The later borrowing into Proto-Slavic is more probable due to the retention of the exact synonym. Compare 🇨🇬 and 🇨🇬.

Adding to that, the maple (Acer) grew only in the western half and particularly the Norway maple (Acer platanoides) as its most widespread kind reached only the western border of the Yamna culture in case that both were even as far distributed from Europe up to there as nowadays. On the one hand, the frequency of the Norway maple is condensed into Europe, on the other hand, it is considered native as well to the eastern end of the Caucasus but this does not exclude it having been introduced as it might not have been recorded. If any maple overall only recently extended up to the Caspian-Pontic steppe and surrounding regions, back then it might not have even been adjacent to the Yamna culture at all. This makes a borrowing from a substrate into ancient or early medieval Indo-European languages substantially necessary. Non-cognate Ancient Greek and Old Armenian  may have a substrate etymology as well even though a possible internal formation was also considered for Ancient Greek.

If Germanic, Latin and Greek words are of native origin, they might derive from which is supposed to refer to the shape of the leaves.
