осот

Inherited from Old East Slavic осътъ (osŭtŭ), from Proto-Slavic *osъtъ. Cognate with Church Slavonic осътъ (osŭtŭ), Ukrainian осо́т (osót), Belarusian осо́т (osót), Slovene ósət, Czech oset (gen. sg. ostu), Polish oset (gen. sg. ostu).

Per Vasmer, from Proto-Indo-European *h₂eḱ- (“sharp”), cognate with Lithuanian ãšutas (“thick horsehair”) (nom. pl. ašutaĩ), also ãšatas, Latvian asns (“sprout”), Ancient Greek ἄκανος (ákanos, “thistle”), ἄκαινα (ákaina, “sharp point, thorn”), ἄκανθος (ákanthos, “acanthus, thorn”), Latin acus (“needle”), acuō (“to sharpen”) (infinitive acuere). Compare осота́ (osotá, “prickly grass; thin riverbank overgrown with sedges”), possibly a contamination of осо́т (osót) with осо́ка (osóka, “sedge”) (also осока́ (osoká)).
