Etymology: "Disclose" is a word about doors. It comes from Old French "desclore," meaning to unclose, built from Latin "dis-," meaning reversal, and "claudere," meaning to shut. To disclose something is literally to unlock what was closed. "Under-" is an English prefix meaning insufficiently or below the proper amount, as in "underfed" or "undercook." Attached to "disclose," it describes opening only partly, leaving the door ajar. Because both parts are common and transparent, this is likely a modern formation built on the spot rather than an ancient inherited term. The same Latin root "claudere" gives English "close," "clause," and "cloister," all words about shutting something in or off.
