The word 'unfolded' is built upon the core Germanic verb 'fold,' which traces back to the Proto-Germanic falthaną, meaning "to fold." The addition of the Old English prefix 'un-' creates a verb of reversal, literally meaning "to reverse the action of folding." The '-ed' suffix marks it for past tense or participle form. Thus, the literal progression from "to bend over" to "to reverse the bending" perfectly captures the modern senses of physically opening something or figuratively revealing information that was previously concealed or "folded up."

Structure: un (reversal) + fold (to bend) + ed (past tense suffix) - un: A prefix of Germanic origin (Old English un-), meaning "not" or "reversal of an action." - fold: A verb of Germanic origin (Old English fealdan), meaning "to bend or double over." - ed: A suffix of Germanic origin (Old English -ode, -ade), used to form the past tense and past participle of regular verbs.
