My wife (American) and I (British) find it invaluable to have two dictionaries - one British English and the other a 'cheaters guide' to incorrect spelling! Seriously, we do find that we often refer to our respective dictionaries for words that are less well known.Wife's review: You wouldn't believe the 'cheater' words that are in that limey dictionary. "Owt"? "Nowt"? Puh-leeez. Seriously, we do learn a lot from both dictionaries. Might call them "marital aids." :-)
