From earlier *tę̑gъkъ, *tęgъka̍, *tę̑gъko (definite *tęgъkъ̀jь), with medial *-ž- taken from the comparative form *tęžьjь, from Early-Proto-Slavic *tingukas. The earlier u-stem based form is indirectly attested in the causative *otęgъčiti (“to burden”). Continues Proto-Balto-Slavic *tingús (mobile accent), from Proto-Indo-European *tengʰ-, morphologically equal to *tę̑gъ + *-ьkъ.
Directly cognate with Lithuanian tingùs (“lazy”) and Proto-Germanic *þunguz (whence Old Norse þungr (“heavy”)). Further akin to Proto-Iranian *θanǰáyati.
