[Opinions] Re: Philadelphia
If we can use "Forever Amber" as a guide, the name was not considered especially unusual in Restoration England (that's around the 1660s.)
But obviously, its didn't last long.
I don't think it's usable. It's super-long, in terms of letter-count, as names go. And unless you're really attached to the city, it's liable to call cheesteaks, notoriously badly-behaved sports fans, or general dirtness to mind. (Many older guys around here who spent time in the city call it Filthadelphia. I can't say I've noticed that it's any dirtier than any other big city, but the tap water is famous for tasting bad.)
Before you criticize a man, walk a mile in his shoes. That way, when you criticize him, you're a mile away and you have his shoes!
