dismay: [13] The underlying meaning of dismay is ‘deprive of power’ – its second syllable is ultimately the same word as the verb may. It comes via Old French desmaier from Vulgar Latin *dismagāre ‘deprive of power’, a compound verb formed from the prefix dis- ‘un-’ and the borrowed Germanic base *mag- ‘power, ability’ (source of English may).
