The vocative 'A' at the beginning is supposed to indicate that you're talking directly to your teacher, right?
In the full phrase, he pronounces it "heatshaT," but if you just tap the single word he says "heatshaTH." Does a final "r" always turn into one of these?
Just a dialect. Various pronunciations of the same word.
This is a tricky one for me to remember!
Whats the deal with the "a"? Is it similar to Spanish's "personal a"?
