ulterior motive, an(redirected from an ulterior motive)
ulterior motive, an
A hidden purpose, a secret reason for saying or doing something. The adjective ulterior originally meant “beyond” or “more distant,” a usage taken from the Latin and dating from the mid-1600s. Less than a century later it began to be used more specifically to mean “beyond what is said or evident.” It then was combined with several nouns—ulterior intentions, ulterior designs, ulterior purpose. Its frequent combination with motive is more recent.
