Well, if we accept beal, it won't be the first "obsolete except dialect" word we've admitted. But I am curious about all you people who keep trying it. Is this word part of your vocabulary, or is it just something you've picked up from crosswords or other puzzles?
I'm not persuaded about bandie.
As for baldie, I'd be interested to know why the Scots named a fishing boat after Garibaldi. Anyhow, despite this intriguing aspect, I think I'd have trouble persuading myself to allow baldie if it weren't for the fact that a few dictionaries list it as an alternative spelling of baldy, being a disparaging term for a bald person.
But if we allow baldie, should we then drop support for the plural baldies? As previous discussions on plurals revealed, there are strong feelings about these matters, but I think baldies should be retained in our list, on the basis that baldy is the far more common singular form.
