oisif

Inherited from Middle French oysif, ouesif, from Old French oisdif, back-formed from oisdive (“idleness”), in turn derived from oisos (“idle”), from Latin ōtiōsus (“idle”). It has the same root as oiseux (“idle, lazy; boring”). Compare the pair Old French voisos (“spoiled; corrupt”) and voisdie, voisdive (“ruse, trick; subtlety, skill”), both from Latin vitiō, vitiāre (“to spoil something”).[1]

     Or, il faut savoir que cet hidalgo, dans les moments où il restait oisif, c’est-à-dire à peu près toute l’année, s’adonnait à lire des livres de chevalerie....

     Yet, it must be known that this hidalgo, in the moments where he remained idle, that is to say just about the whole year, devoted himself to reading books of chivalry....
