About appose vs oppose
These two spellings originally meant the same thing, but now “appose” is a rare word having to do with placing one thing close to or on something else (compare with juxtapose). It mainly occurs today as an error spelling-checkers won’t catch when the word intended is “oppose,” meaning to be against something. If you object to a proposed course of action, you are opposed (not “apposed”) to it.
