Yea vs. Yay (and vs. Yeah)

yay!!So, three words, homophones, where a homonym would work perfectly well. Okay, “yeah” is pronounced a bit differently.

As I understand it:

  • Yea = an affirmative vote. Rhymes with, but opposite to, “nay.”
  • Yay = I’m really happy
  • Yeah = a slacker’s “yes”

Would the use of the wrong one ever be misinterpreted? Yea… or would that be yeah? Yay.
