Etymology 1[edit]

From Middle High German tag, tac, from Old High German tag, tac (attested since the 8th century); from Proto-West Germanic *dag, from Proto-Germanic *dagaz, from Proto-Indo-European *dʰegʷʰ- (to burn, to be illuminated).

Germanic cognates include Old Saxon dag (whence German Low German Dag), Old Dutch dag (whence Dutch dag, Afrikaans dag), Old English dæġ (whence Modern English day), West Frisian dei, Old Norse dagr (whence Icelandic dagur, Faroese dagur, Norwegian dag, Swedish dag, Danish dag), Yiddish טאָג(tog) and Gothic 𐌳𐌰𐌲𐍃 (dags).

Non-Germanic cognates include Albanian djeg (to burn), Latin foveo (to warm, nurture), favilla (cinders, ashes), Ancient Greek τέφρα (téphra), Lithuanian dãgas (hot season), Russian жечь (žečʹ, to burn), Sanskrit दहति (dahati, to burn).

Although they are similar in appearance and meaning, German Tag and Proto-Germanic *dagaz are not related to Latin diēs as older folk etymology suggested; instead, the Latin word is derived from Proto-Indo-European *dyew- (to shine). See the Latvian diena (day) and Sanskrit दिन (diná, day) for more.[1]
