No, mercy, above, is not misspelled. Let me explain. I often “suffer” from language interference, and I love it. Having an extra language or two to rely on makes life more interesting.
We often use the phrase, “It’s Greek to me,” but that’s not my complaint. It can be Greek, Latin or one of its kin, Spanish, French, or English. It’s all my cup of tea, to use a well-worn cliché.
