A hidden agenda

Origin

The word "agenda" itself descends from the Latin agenda, meaning "things to be done." It originally marked a simple list of items for discussion in a meeting, or a broader program of action. But human nature, being what it is, rarely stays simple. When we add "hidden" to the mix, we conjure an entirely different beast. While the concept of secret motives has haunted human interaction since ancient times—think of every political intrigue or boardroom power play—the specific phrasing "hidden agenda" truly took hold in the 20th century. It emerged as a sharp, efficient shorthand, especially in the realms of politics and business, to describe that gnawing suspicion when someone's stated intentions just don't quite add up, hinting at a deeper, often self-serving, master plan secretly unfolding beneath the surface.
