派生 restively adverb restiveness noun 语源
late 16th cent.: from Old French restif, -ive, from Latin restare 'remain'. The original sense, 'inclined to remain still, inert', has undergone a reversal; the association with the refractory movements of a horse gave rise to the current sense 'fidgety, restless'
