forbidden

The word 'forbidden' originates from the Old English verb 'forbēodan', a compound of the intensive prefix 'for-' and the verb 'bēodan', meaning "to command" or "to offer". The prefix 'for-' here acts as a prohibitive or negative force, turning the core meaning from "to command" to "to command against, to prohibit". This Old English formation directly parallels the development of its German cognate, 'verbieten'. Over centuries, the strong verb conjugation shifted, and the past participle 'forboden' evolved into the modern 'forbidden', solidifying its role as an adjective describing something that has been authoritatively prohibited.

Structure: for (away, against) + bid (command, offer) + en (past participle suffix) - for: Old English, a prefix meaning "away, off, against, completely". - bid: Old English, a verb meaning "to command, order, proclaim, offer". - en: Old English, a suffix used to form the past participle of many strong verbs.
