Where do you go? How do you go? When do you go? There you go?
These questions we ask every day except when verbalized most people say Where do ya go? How do ya go? When do ya go?
There ya go?
“A” can be correctly pronounced as the letter “A” in the alphabet. It can also be pronounced as “uh” (generally called schwa by teachers and linguists) with complete correctness. There are also regional variences in the way “a” is pronounced. All of them are correct.
