You tell me Canceled or Cancelled? How do you spell it and where do you live?
Canceled is the US version and cancelled is the British (and assuming the rest of the world where english is spoken) version.
That bugs me, I am an American and I find it offensive to use only one "L", it goes against correct grammar (Yes, I am sure you will find my grammar is not perfect either, but that is not the point - at least I admit it).
According to grade school grammar there are supposed to be 2 of the "L"s to keep the pronounciation of the word "cancel" the same, otherwise using only one "L" will make the last "E" in the word "cancel" a long "E" like the ee sound in feet. This is because the "E" in the "-ED" that is added only 1consonant awayfrom it, and again as grade school grammar taught us, when two vowels are seperated by only 1 consonant and the last of the two are a strong vowel (like "e") that will make the first vowel long. So, technically, when it is written "canceled" it should be pronounced "can-seel-d". This is why the English rule is to double the last consonant, to keep that last "E" (or any last vowel) short, which would maintain the correct pronounciation of the word. Or is it we do not remember how to read, write, or learn anything productive?
