Reconstruction:Proto-Balto-Slavic/aráiˀsas

This Proto-Balto-Slavic entry contains reconstructed terms and roots. As such, the term(s) in this entry are not directly attested, but are hypothesized to have existed based on comparative evidence.

Probably borrowed from a substrate (with the onset *a- perhaps being a prefix in said substratum language), with no certain cognates in non-Balto-Slavic languages; that said, compare Albanian arrë (“walnut”), Ancient Greek ἄρυα (árua, “Heraclean filbert”). The connection to Proto-Slavic *rěšiti (“to untie, solve”),^[1] the latter probably from Proto-Indo-European *wreyḱ- (“to twist, bend”), is semantically unconvincing,^[2] and Smoczynski's derivation from a Proto-Indo-European *(h₁)reyḱ- (“to tear, break”), which he connects to Ancient Greek ἐρείκω (ereíkō, “to break, bruise, crush, burst”),^[3] is formally difficult.
