This ticket is to add language codes for the representations of lexemes and forms in American English.
As there are already separate codes for British and Canadian English (inherited from the quirks which led to their inclusion as termbox languages), and given that there are a number of lexemes for which American English spellings are distinct from what might be considered an international de facto standard, it would make sense to be able to better distinguish these in lemmata and forms rather than consign them to the 'ambiguous' (i.e. not otherwise qualified) realm.
@Amire80 @jhsoby What do you say?
