Its because the Britons kept getting invaded and getting their butts kicked
So modern English is a weird mixture of Latin, Celtic, Danish, German and French
Until they figured out they lived on an island and could just build a navy. But this was after they got kicked out of France.
Then they started kicking everyone elses butts and actually ruled the world for a time (except Continental Europe, which they got kicked out of)
There was also the Great Vowel Shift. At one point the e maybe have pronounced, like it would be in German and French. "Table" is itself a french loan word, from "tableau"
