Ok, gonna try to use this instead of twitter. Sociolinguistics question: vowel shifts! This is possibly a obvious question - there are some examples where vowel shifts seem to have social causes (northern cities shift), but are there any that just look random, or a general trend to shift which doesn't have a social cause?
@impractknow hi! I'm no longer a practicing linguist, but my degree is in pragmatics
@gretchenmcc will be better able to help, if she's around
