My wife recently sent a wordy e-mail filled with all sorts of questions and comments to our ten-year-old granddaughter who sent back the one-word reply, “Ya.” When asked, GD explained that “Ya” just means she read it.
Good idea, I thought. I’ll start using it myself. So often I receive an e-mail that doesn’t require an answer, but I want to let the sender know I read it, understood it, and at least generally agree with it. It’s sort of like the written counterpart of “uh-huh” used in speech.
