text: No -  imaginative, but incorrect.\n\nThe word Zion is a representation of a Hebrew word  tsiyyon which is unrelated to any of the other words you have mentioned.\n\nTheo- as in theology is Greek, but also unrelated to the others.\n\nZeus, on the other hand, IS the Greek equivalent of Latin deus, and Germanic Tiw, the god that Tuesday is named after.\n\nThe older form of Deutsch was Thiudisc; although in modern German, the H in such words makes no difference in pronunciation, this was not originally the case. Old English Theodisc is to Deutsch as Theof to Dieb (thief); if the word had carried on into modern English, instead of saying German, we would say maybe Thedish, like Swedish. The original sound of the TH was as i English thief.\n\nBut Theodish is Anglo-Saxon did not mean specifically German; on the contrary, it meant national, related to a Gothic word Thiuda meaning people, which has some related words in other Indo-European languages.\n\nThe sound represented by TH in Theodisc etc. was always distinct from the T sound of Tiw, etc. They are not plausibly related. Deutschland just means National land, the land belonging to a people.
