вИлка, but not вилкА

Asking the real questions here

Could this never mean "BUT where is the fork?"

Jenny left it with the luggage in the taxi

You use и in one phrase like: мама и папа. And you use а if there're two different phrases like: Это мама и папа, а это бабушка. If you translate а as "and" or "but" depends on the context, so you can use both as well.

When do we translate the letter "а" in sentence, because I see sometimes don't translate it.

So how would i say "where is a fork" instead of THE fork?

In college I was taught that "а" could translate to "and" or "but." Was that wrong?

А где вилка

"There is no spoon!" "And where is the fork?"

The stress in word "вилка" is wrong

Неправильное ударение. Правильно на 1й слог -вИлка
