Proto-Slavic

Etymology

From Proto-Indo-European *pleth₂- (“flat”) + *-sno, cognate with Lithuanian plẽkšnė (“bottom, foundation”), plesnà (“foot”), Latvian pleksna (“bottom of foot”), Old Prussian plasmeno (“bottom of foot”) (probably all of them derived from Proto-Balto-Slavic *pletsna). Further related to Proto-Slavic *pleťe (“shoulder, scapula”)

Alternative form with -ju- vocalism is probably from related root *pleh₂(w)-, akin to Latin plautus (“flat-footed”).

sole (bottom surface of the foot)
