Etymology

It is inherited from Middle High German dienstac, borrowed from Middle Low German dingesdach, a Low German and Lower Rhenish name that spread into High German.[2][3][4] The same Lower Rhenish word is Middle Dutch dinxendach and Dutch dinsdag.[2][3][5]

The names of the weekdays were modelled on the Latin names of the planets and their gods, with native gods put in their place; the Latin model of this day was Mārtis diēs (“day of Mars”), whence French mardi and Italian martedì.[2][3][6] The first part of the Low German name is usually traced to Latin Thingsus, a byname of Mars on an altar inscription set up by Germanic soldiers in the 3rd century, read as “protector of the thing” (the assembly).[2][3][6][4] Kluge notes that nothing else is known of this god, and that the name might instead mean “day on which the thing is held”.[2] Pfeifer considers giving up the link with Thingsus and deriving the Lower Rhenish forms from the older Proto-Germanic *tīwas-dagaz, with /t/ replaced by /d/ to remove the heathen god's name and an /n/ added after the names of other weekdays.[3]

That older name contains Proto-Germanic *tīwaz, the god equated with Mars: Old Norse Týr, Old English Tīw, Old High German Ziu.[2][3] It is continued in Old Norse týsdagr, Old English Tīwesdæg, Old Frisian tīesdei and ziostag, Alemannic Ziestag, and in English Tuesday and Swedish tisdag.[2][3][5] The god's name originally meant “divine” and corresponds to Latin dīvus; it is closely related to the name of the Indo-European sky god, Ancient Greek Ζεύς (Zeús) and Iuppiter.[2] Bavarian Ergetag has another source again: a loan translation of Ancient Greek Ἄρεως ἡμέρα (Áreōs hēméra, “day of Ares”), probably brought by the Gothic mission.[2][7][6]

Earliest recorded meaning

The word is found from the 13th century in Dutch, Low German and western Central German: Low German charters of that century have dinsdag, dinsedag, dinstag and dingstag.[5][8] Middle High German dienstac is attested from the 13th century, among others in the Prosa-Lancelot (1240–1250).[9]

Semantic evolution

From the Lower Rhine the word reached East Central German in the 14th century and then, slowly, the south, where it pushed out Alemannic Ziestag and Bavarian Ertag; these survive in the dialects.[3][5][6] Only from the second half of the 17th century is Dienstag the general form of the written language.[5][3] In the 15th and 16th centuries the Upper Rhine had a mixed form zinstag.[8][7] The bishopric of Augsburg also used Aftermontag “after-Monday”.[7]

The long vowel ie appears from about the 14th century and won through in the 17th, helped by a popular association with Dienst “service”.[5][7] Forms with a velar, such as dingstag, lived on in Low German, Rhenish and East Central German and in the modern dialects.[5]
