Jill in Indianapolis, Indiana, wonders how to spell the one-syllable cheer that starts with Y. Is it yay or yea? Since the 1930s, yay has been used as a little celebratory word. The word yea is much older and used in formal texts to mean “indeed.” An example is in the psalm that contains the verse Yea, though I walk through the valley of the shadow of death. This is part of a complete episode.
