The name Tuesday comes from a Middle English word, Tiwesday. This word came from the Old English word Tiwes dæg. This was named after the Nordic god Tyr
“Tyr and Fenrir” by John Bauer (1911)
Tyr (pronounced like the English word “tier”; Old Norse Týr, Old English Tiw, Old High German Ziu, Gothic Tyz, Proto-Germanic Tiwaz, “god”[1][2]) is a Norse war god, but also the god who, more than any other,
presides over matters of law and justice.
