The word "voiceless" is a transparent English compound formed from the native noun "voice" and the adjectival suffix "-less." The root "voice" traces back to the Proto-Indo-European (PIE) root wekw-, meaning "to speak," which evolved into Latin vox (genitive vocis). This Latin term passed into English via Old French. The suffix "-less" originates from the Old English adjective lēas, meaning "free from" or "devoid of." The literal combination, "devoid of voice," logically extends from describing a person who cannot speak to a precise linguistic term for sounds produced without vocal cord vibration, demonstrating a clear semantic path from physical description to technical phonetic classification.

Structure: voice + less - voice (from Latin vox, voc- meaning "voice, sound, word" via Old French voiz; functions as the core noun root denoting sound produced by the larynx.) - less (from Old English -lēas meaning "devoid of, free from"; functions as an adjective-forming suffix meaning "without".)
