The Origin of Kiln

The word kiln comes from Old English cyln, which came from the Latin word culina, meaning “kitchen” or “cooking place.” Over time, the spelling changed, but the meaning stayed linked to heat and firing.

The silent “n” at the end of kiln causes confusion. English kept the letter in spelling but softened it in speech. This mismatch between spelling and pronunciation is common in English and explains why people sometimes write kilm instead.

The spelling difference exists because English spelling evolved slowly, while pronunciation changed faster.
