Unbosom → It is formed from "un-" (meaning not or opposite) and "bosom" (from Old English "bōsm", meaning the chest or heart). The word "unbosom" means to reveal or disclose one's innermost thoughts or feelings, essentially to open one's heart.
Think of 'un-' meaning to 'not' keep something hidden and 'bosom' referring to the heart or chest — so unbosom means to open your heart and share your feelings.
