Uncertain origin. Traditionally suggested to be a compound of manus (hand) + turbare (to unsettle, throw in to disorder), or a deformed compound of manus (hand) + stuprare (to defile (the self)), from stuprum, with influence from turbare.

Watkins traces the root to a Proto-Indo-European *mostr̥g-, extended and metathesised from *mosg- (marrow), also found in Avestan mast(ə)rəg-an- (mast(ə)rəg-an-, brains) and Tocharian B mrestīwe (marrow); the semantic development would parallel "the symbolic autofellatio of Finn [mac Cumaill]'s gnawing his thumb to the marrow".[1]
