enfetter

The word 'enfetter' is a relatively transparent English formation. Its core, 'fetter', descends from the Old English 'feter', a term for a shackle or chain used to restrain the feet, which itself has Proto-Germanic roots. The prefix 'en-', of Old English origin, is a versatile verb-forming element meaning "to put into" or "to cause to be." Therefore, the literal construction of 'enfetter' is "to put into fetters." This logical combination, where a concrete object (a fetter) is transformed into an action by a causative prefix, directly yields the modern abstract meaning: to bind, restrain, or confine someone or something, whether physically or metaphorically.
