100+ Differences between British and American English | British vs. American Vocabulary Words

I'm a 'northern lass' and in my 76 years I have never ever heard anyone use the word 'childer' either in my home town or county. Equally from the many times I've been to the counties which form 'the north' I've never come across the word. That's not to say for certain that it isn't used somewhere in the north but I can safely say that it is certainly not in common usage. I did come across this in the Yorksire Dialect Dictionary when the word was in use there .... ;)
