I always get “mad” (we don’t actually get upset with each other) at a friend of mine because he uses the UK versions
for the past tense of verbs like spill or spell, saying spilt or
spelt instead of the American versions like spilled or spelled, etc. He’s “retaliated” (just teasing) by saying ✻feeled and ✻builded rather than felt
Does anyone know why American English changed ‑t to ‑ed only for certain
verbs but not for others?
