Etymology

Origin of ulterior

First recorded in 1640–50; from Latin: “farther,” comparative of ulter “beyond”; akin to ultrā “on the far side”; cf. ultra-

Explanation

An ulterior interest, argument, or revelation is one you try to keep hidden, like your ulterior motive for weeding your grandmother's garden is to have a conversation with your crush — and Grandma's neighbor — who happens to be outside, too. The adjective ulterior is a Latin word which means “more distant” or “future.” Something that is ulterior may lay the groundwork for what comes later, like a new friend who hangs out with you at your house but whose ulterior motive is to date one of your siblings, or the incredible popularity of a series of novels set in a real place having the ulterior consequences of that place becoming a tourist destination.
