Unrelated, but:

from whence

Did you know “whence” means “from where,” so it’s not really necessary to say “from whence?” It’s not a mistake, exactly, because “from whence” has been around forever and is considered acceptable usage. “Whence” without the “from” seems, though, to be more correct in a sense, and has certainly been more common for a long time.
