maddening

The word 'maddening' is built upon the core concept of 'mad', which traces back to the Old English 'gemǣd', meaning 'insane' or 'frenzied'. The verb 'madden' was formed by adding the causative or inchoative suffix '-en' to 'mad', creating the sense 'to make mad' or 'to become mad'. The addition of the present participle suffix '-ing' transforms the verb into an adjective, describing something that has the quality or effect of driving one to madness. Thus, the literal meaning, 'causing madness', evolved into the modern abstract sense of being intensely irritating or exasperating.
