Usage: Use upper to describe something situated at a higher physical location or holding a superior social status, such as an upper floor or upper class. It often pairs with nouns like deck, crust, or management to indicate elevation in space or hierarchy.
The word upper comes directly from Middle English and originally meant the same thing it does today. Although its structure suggests a combination of "up" and "-er," this formation is simply how speakers analyzed the word rather than its true origin.
