Týr (pron.: //; Old Norse: Týr [tyːr]) is a god associated with law and heroic glory in Norse mythology, portrayed as one-handed. Corresponding names in other Germanic languages are Gothic Teiws, Old English Tīw and Old High German Ziu and Cyo, all from Proto-Germanic *Tîwaz (*Tē₂waz). The Latinised name is Tius or Tio.
In the late Icelandic Eddas, Tyr is portrayed, alternately, as the son of Odin (Prose Edda) or of Hymir (Poetic Edda), while the origins of his name and his possible relationship to Tuisto (see Tacitus' Germania) suggest he was once considered the father of the gods and head of the pantheon, since his name is ultimately cognate to that of *Dyeus (cf. Dyaus), the reconstructed chief deity in Indo-European religion. It is assumed that Tîwaz was overtaken in popularity and in authority by both Odin and Thor at some point during the Migration Age, as Odin shares his role as God of war.
Old Norse Týr, literally "god", plural tívar "gods", comes from Proto-Germanic *Tē₂waz (cf. Old English Tīw, Old High German Zīo), which continues Proto-Indo-European *deiwós "celestial being, god" (cf. Welsh duw, Latin deus, Lithuanian diẽvas, Sanskrit dēvá, Avestan daēvō "demon"). And *deiwós is based in *dei-, *deyā-, *dīdyā-, meaning 'to shine'.
The earliest attestation for Týr's continental counterpart occurs in Gothic tyz "the t-rune" (𐍄) in the 9th-century Codex Vindobonensis 795. The name is later attested in Old High German as Cyo in the A Wessobrunn prayer ms. of 814. The Negau helmet inscription (2nd century b.c.) may actually record the earliest form, teiva, but this interpretation is tentative.
Týr in origin was a generic noun meaning "god", e.g. Hangatyr, literally, the "god of the hanged", as one of Odin's names, which was probably inherited from Tyr in his role as god of justice. The name continues on as Norwegian Ty, Swedish Tyr, Danish Tyr, while it remains Týr in Modern Icelandic and Faroese.
West Germanic Ziu/Tiw/Tiwaz

The Excerptum ex Gallica Historia of Ursberg (ca. 1135) records a dea Ciza as the patron goddess of Augsburg. According to this account, Cisaria was founded by Swabian tribes as a defence against Roman incursions. This Zisa would be the female consort of Ziu, as Dione was of Zeus.
The name of Mars Thingsus (Thincsus) is found in an inscription on an 3rd century altar from the Roman fort and settlement of Vercovicium at Housesteads in Northumberland, thought to have been erected by Frisian mercenaries stationed at Hadrian's Wall. It is interpreted as "Mars of the Thing". Here is also worth noting what Tacitus stated in his work Germania about capital punishment amongst the Germanic folk; that none could be flogged, imprisoned or executed, not even on order of the warlord, without the consent of the priest; who was himself required to render his judgement in accordance with the will of the god they believe accompanies them to the field of battle. In the same source this god is stated being the chief deity.
Tacitus also named the German "Mars" as the primary deity, along with the German "Mercury", associated with the Germanic custom of the disposal of the spoils of war; as practiced from the 4th century BC to the 6th century AD.
In the Old English Rune Poem, the rune that is otherwise named for Tiw in the other rune poems (Abecedarium Nordmanicum, Old Norwegian Rune Rhyme, Old Icelandic Rune Poem), is called tir, meaning "glory". This rune was inscribed on more Anglo-Saxon cremation urns than any other symbol.
There is sketchy evidence of a consort, in German named Zisa: Tacitus mentions one Germanic tribe who worshipped "Isis", and Jacob Grimm pointed to Cisa/Zisa, the patroness of Augsburg, in this connection. The name Zisa could be derived from Ziu etymologically.
North Germanic Tyr 
According to the Poetic Edda and Prose Edda, at one stage the gods decided to shackle the Fenris wolf (Fenrir), but the beast broke every chain they put upon him. Eventually they had the dwarves make them a magical ribbon called Gleipnir. It appeared to be only a silken ribbon but was made of six wondrous ingredients: the sound of a cat's footfall, the beard of a woman, the roots of a mountain, bear's sinews (meaning nerves, sensibility), fish's breath and bird's spittle. The creation of Gleipnir is said to be the reason why none of the above exist. Fenrir sensed the gods' deceit and refused to be bound with it unless one of them put his hand in the wolf's mouth.
Tyr, known for his great wisdom and courage, agreed, and the other gods bound the wolf. After Fenrir had been bound by the gods, he struggled to try to break the rope. Fenrir could not break the ribbon and enraged, bit Tyr's right hand off. When the gods saw that Fenrir was bound they all rejoiced, except Tyr. Fenrir will remain bound until the day of Ragnarök. As a result of this deed, Tyr is called the "Leavings of the Wolf"; which is to be understood as a poetic kenning for glory. After a heartbreaking battle (of Ragnarök) Fenrir swallowed Odin the All-father, whole.
According to the Prose version of Ragnarok, Tyr is destined to kill and be killed by Garm, the guard dog of Hel. However, in the two poetic versions of Ragnarok, he goes unmentioned; unless one believes that he is the "Mighty One".
In the Hymskvidha, Tyr's father is named as the etin Hymir – the term "Hymir's kin" was used a kenning for etinkind – while his mother goes unnamed, but is otherwise described in terms that befit a goddess. This myth also pairs Tyr with Thor, and draws a comparison between their strength via the lifting of Hymir's cauldron. Thor proves the stronger, but other than Thor's own son, Magni, Tyr is the only deity whose strength is ever questioned in comparison to the Thunderer's.
Tiwaz rune 
The t-rune ᛏ is named after Tyr, and was identified with this god; the reconstructed Proto-Germanic name is *Tîwaz. The rune is sometimes also referred to as *Teiwaz, or spelling variants.
The rune was also compared with Mars as in the Icelandic rune poem:
ᛏ Týr er einhendr áss
Tyr is a one-handed god,
Lexical traces 
In the sphere of organized warfare, Tyr/Tiw had become relatively unimportant compared to Odin/Woden in both North and West Germanic by the close of the Migration Age. Traces of the god remain, however, in Tuesday (Old English tíwesdæg "Tiw's day"; Old Frisian tîesdei, Old High German zîestag, Alemannic and Swabian dialect in south west Germany (today) Zieschdig/Zeischdig, Old Norse týsdagr), named after Tyr in both the North and the West Germanic languages (corresponding to Martis dies, dedicated to the Roman god of war and the father-god of Rome, Mars) and also in the names of some plants: Old Norse Týsfiola (after the Latin Viola Martis), Týrhialm (Aconitum, one of the most poisonous plants in Europe whose helmet-like shape might suggest a warlike connection) and Týviðr, "Tý's wood", Tiveden may also be named after Tyr, or reflecting Tyr as a generic word for "god" (i.e., the forest of the gods). In Norway the parish and municipality of Tysnes are named after the god.
German Dienstag and Dutch dinsdag (Tuesday) might be derived from Mars Thingsus, as mentioned above.

- Tyrseng ("Tyr's Meadow"), Viby, Jutland, Denmark. Once a stretch of meadow near a stream called Dødeå ("Stream of the Dead" or "Dead Stream"), where ballgame courts now exist. Viby contained another theonym; Onsholt ("Odin's Holt") and religious practices associated with Odin and Tyr may have occurred in these places. A spring dedicated to Holy Niels that was likely a Christianization of prior indigenous pagan practice also exists in Viby and the city itself may mean "the settlement by the sacred site". Traces of sacrifices going back 2,500 years have been found in Viby.

Personal names 
A number of Icelandic male names are derived from Týr. Apart from Týr itself: Angantýr, Bryntýr, Hjálmtýr, Hrafntýr, Sigtýr, Valtýr and Vigtýr. When Týr is used in this way, joined to another name, it takes on a more general meaning of "a god" instead of referring to the god Týr. For example, Hrafntýr "raven-god" and Valtýr "god of the slain" are Old Norse names of Odin.
