AJ wrote this in another thread:
I would have hyphenated wood-panelled (UK spelling)
I looked up dictionary.com which says this:
verb (used with object), pan路eled, pan路el路ing or (especially British) pan路elled, pan路el路ling.
I gave up trying to figure out from the principles involved whether to double the consonant a long time ago. I rely on spellcheckers. As far as I know it only applies to root words of one or two syllables (i.e. don't count syllables in any prefix), and it depends on which syllable is emphasised.
Then AJ's post landed on me like a 16-ton weight. American and British are different!?
Can anyone describe what the principles involved are? But please, say whether you're describing the British or American style!
Alternatively, can anyone provide any links which explain them.
