It's not the answer, but it's the answer I expected.
The KJV, however, says, "Forgive us our debts" (as do the Bibles that came before it in the 16th century). I used to teach a Bible history class for Sunday school at my church, and I often started with a straw poll. Roughly half the group would say "debts," and half would say "trespasses."
I myself would say the latter. I theorize, though I have no evidence yet to support it, that whether you prefer "debts" or "trespasses" depends on whether you were raised with the KJV or not. I wasn't.
"Trespasses" actually comes from the Book of Common Prayer rather than a particular English Bible.
