In the beginnynge was the worde and the worde was with God: and the worde was God.
John 1:1 (Tyndale Bible 1534 by William Tyndale)
Why did Tyndale (1525) did not capitalize 'word' in John 1:1?
I expect a lot depended on the printer. Here are two early printings. In each, notice that not only is "worde" not capitalized, but neither is "god".
This one is the first of Tyndale's New Testaments (later revised): the 1525 printing from Cologne:
And this is John 1 from the 1526 Peter Schoeffer printing which similarly set in uppercase the first words of sentences, and few others:
If the bible interprets the bible then the proper understanding of John 1 would be found in Issaih 55 The father says "I will send out my word and it shall not come back empty" I, the father "singular" my word "His singular" "and it" not he, or she! By the breath of my mouth (His words) he spoke and it came in to existence Ps.33:5-6 There is nothing complicated about this!
The problem with quoting Greek sentence structure and outside of the Bible explanations is exactly what user49 said it’s not complicated when the Bible interprets the Bible ! All other explanations are here say and agenda driven. Jehovah the father alone is God! There is no other ! Jesus is not God he is the begotten son of God. Hosea says I’am God not man! Jesus says in Rev.3 “to him who overcomes I will make a pillar in the temple of my God. Jesus worships the same God as Abraham Moses The apostles does. Therefore if you worship God you are not God.
