Accepted Answer

[ʌl'tɪriər] 
ulteriorlying beyond what is openly revealed or avowed (especially being kept in the background or deliberately concealed)
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.
