Germany in the German Language is Deutschland (Land of the Deutsch), the word Deutsch as well as Tysker, Tuatha, Teuta, Tuitus is derived from Tiwar, from *tew in PIE, which can mean army, or strong, as in military strength. Tyr was the War God, father of the Tuatha. The Gauls had Teutates as their ethnic god also.

>The supposed Hittite cognate 𒌅𒍖𒍣𒅖 (tuzziš, “army; camp”) with the semantic shift "people" > "army" > "camp" has been criticized to be unlikely (the normal development would be "camp" > "army"). Kloekhorst furthermore argues that the Hittite word can formally only reflect an i-stem tewt-i-, and finally endorses an alternative etymology proposed by Melchert, from PIE *dʰh1-uti-

>Often a derivation from either of the roots *tewh2- (“to be strong; swell”, referring to the strength of community) and *tewH- (“to look favorably; protect; observe”) + *-téh2 is considered, but the presence of a laryngeal renders that suspect

The word týr also came to mean god generically. Which proves that Teiwaz is indeed the mightiest of the Germanic gods, as his name is a powerful one. Hence Odin is Sigtýr (god of victory), Rúnatýr (god of runes), Fimbultýr (mighty god), Hertýr (god of hosts). It is because Týr (< *tīwaz) is cognate Latin deus, sanskrit devá (Devas are what the Vedic gods are called, while in Zoroastrianism the Daevas are demons) and Avestan daēuua, and Lithuanian diẽvas going back to PIE *deywós.
