undue

When something isn't appropriate or justified, you can describe it as undue. For example, an undue delay in a hospital waiting room can be dangerous for someone with a bad injury.

Something that's undue isn't warranted or, often, fair. The phrase "undue delay" is a common one, and it means that someone has to wait way too long for something, whether it's a building permit or a dentist appointment. The adjective has come to mean "excessive," from its original definition in the fourteenth century as literally "not owing" or "not payable."
