Reconstruction:Proto-Slavic/gleznъ

Uncertain. Both Derksen and Trubachyov point a relation with Old Norse klakkr (“bump, hillock”), Norwegian klakk, dial. Swedish klakk (“heel (shoe); knoll in the field”), Middle High German klac (“a bang, crack, split”) (from pre-Germanic *gloǵno-), which would make the lemma a descendant of Proto-Indo-European *gleǵn- (see Proto-Slavic *glazъ (“ball, eye”) for further etymology). This etymology however demands that Winter's law was not applied in most of the descending forms.

Georgiev draws comparison with Sanskrit ग्लह m (glaha, “gaming, dice”).
