Time to scratch it. Or to get out the Grammar Hammer®. This has bugged me for a long time, and after having seen it on the umpteenth blog/Facebook post:
Yea – pronounced “yay.” As in, “Yea, though I walk through the valley of the shadow of death…” An affirmative vote (“yea” vs. “nay”).
Yeah – pronounced “y.” As in, “She loves you, yeah, yeah, yeah.” Slang for “yes,” and a variant of the above “yea.”
Yay – prounounced “yay.” Slang. As in, “Huzzah! The Indians are 14-8! Yay!”
You left out a couple:
Ye Ha – (var. spelling: Yee Hah!). Pronounced as shown. A Southern version of ‘Yay’. Commonly shouted at the top of one’s lungs accompanied by tossing headgear in the air.
Heya – pronounced Hee-Yah. A Southern version of ‘Here’. “Y’all stay heya whahl Ize gits us a mess o’ frahed chickin”
Hey, it looks like it’s just the two of us around here lately. Hmmm. Was it something I said? Or something YOU said?
Moi?!?!? *looks around nervously*
You should show this to Band Dude. He does it all the time. -.-
