The name
Tuesday derives from the Old English and literally means "Tiw's Day". Tiw is the Old English form of the Proto-Germanic god
*Tîwaz, or
Týr in
Old Norse.
*Tîwaz derives from the
Proto-Indo-European base
*dei-,
*deyā-,
*dīdyā-, meaning 'to shine', whence come such words as "
deity". The German
Dienstag and Dutch
dinsdag are derived from the Germanic custom of the
thing, as Tiw / Týr also had a strong connection to the thing. The
Latin name ("day of Mars") is equivalent to the
Greek (, "day of
Ares"). In most languages with
Latin origins (
Italian,
French,
Spanish,
Catalan,
Romanian,
Galician,
Sardinian,
Corsican, but not
Portuguese), the day is named after
Mars, the Roman parallel of the
Ancient Greek Ares (). In some
Slavic languages the word Tuesday originated from
Old Church Slavonic word meaning "the second". Bulgarian and Russian () ( ) is derived from the Bulgarian and Russian adjective for 'second' – () or (). In
Japanese, the second day of the week is (), from (), the planet
Mars. Similarly, in
Korean the word Tuesday is (), means literally fire day, and Mars the planet is referred to as the fire star with the same words, but this is unrelated to the Roman god Mars, which is referred to phonetically as Mars. In the
Indo-Aryan languages Pali and
Sanskrit the name of the day is taken from ('one who is red in colour'), a
style (manner of address) for
Mangala, the god of war, and for Mars, the red planet. In the
Nahuatl language, Tuesday is () meaning "day of
Huitzilopochtli". In
Arabic, Tuesday is (), and in
Hebrew it is (), meaning "third day". When added after the word / ( or ) it means "the third day". ==Religious observances==
