How did "th" become "d"? In other words, where did "dis" and "dat" come from?

@KebleBollyJocksford The answer to your question is that language changes all the time. 'Y' used tho sound like 'TH'. 'J' used to sound like 'Y'. 'V' sounded like 'W'. The list goes on. In America that forgot how to spell the 'TH' becoming 'D' began in the black ghettos where children were not corrected on their pronunciation.

@KebleBollyJocksford I studied the English language. Those sounds are what Shakespeare would recognize. 'Ye olde inn' sounded like 'the old inn'. Jehovah sounded like Yahweh. If you talked to the king your would have used the respectful word 'you'. If you talked to your buddies you would used the familiar word 'thee'.

@KebleBollyJocksford It is a habit that is dying out with the more modern translations of the Bible. I have never referred to God as Thee. I almost never hear it except from those who think the KJV is the only translation. I don't like and never have. It is poorly translated and even worse we don't speak that form of English anymore.

@KebleBollyJocksford I am sure you can find samples of people who think they must use arcane language. It simply shows me who doesn't have a real relationship with God.
