cancelation (plural cancelations)
- Alternative spelling of
Despite the widely used form of "canceled" vs. "cancelled" in American English, the word "cancellation" is still much more widely used than the variant "cancelation".
The reason for the confusion: When you turn the verb “cancel” into past tense, the word stays the same number of syllables (two), so it’s a matter of location whether you use two L’s or one. The -ation that turns the word into a noun, on the other hand, puts a whole new syllable (in fact, two) after the L. The double-L is a like a bridge to those new syllables.
