- n. masturbation
from The Century Dictionary and Cyclopedia
- n. Masturbation.
From Latin manus ("hand") + stuprō ("debauch"). The verb is often quoted as stupō, stupare. (Wiktionary)
In this translation, I prefer for such cases to use the words _masturbation_ (i.e. _manustupration_) and _masturbatory_; and to limit the use of the terms _onanism_ and _onanistic_ to cases in which no direct use is made of the hand.
