The difference between "ya", "yea", and "yeah".
Ya is a short a. Like Pa.
Yea is a long a. Like hooray.
Yeah is a short e and a short a combined.
Use the right one.
Now, I have to take issue with you here:
If Ya is like Pa, it's not a short a, it's a pure vowel,
ar as in arm
Yea is not a long vowel, it's a diphthong, like the sound in d
ayYeah is a short vowel, just
e like in end
And yes, I said I was a pedant
