Faineant (FAY-nee-uhnt) (adjective) – Idle, ineffective
(noun) – a do-nothing; idler.
(From French fainéant, alteration of fait-néant (literally, does nothing) So a mistaken assumption about the derivation of the word turned the original French faignant (feigning) into faineant (does nothing), the present form. In French history, many kings have been called les rois fainéants as the real power was in the hands of mayors of the palace)
Yours is the faineant spirit of the decadent.

Asthenia (as-thee-nee-uh)(noun) –
