Adjectival form of 'Indolence'
1. Avoiding labor and exertion; habitually idle; lazy; inactive.
2. Conducive to or encouraging laziness or inactivity.
3. Causing little or no pain
4. Slow to heal, develop, or grow
Origins:
From Latin "Indolencia" meaning "freedom from pain", from the prefix 'in' (not) and 'dolens' (grieving, suffering).
The sense of "laziness" inherent in the modern term begins c1710 from the notion of not 'taking pains' or being 'painstaking', thus "avoiding trouble", or being lazy.
"People are scared of laziness and persecute those who accept it, and it always happens because no one realizes laziness is the truth; it has been branded as the mother of all vices, but it is in fact the mother of life. In his folly, the son scorns his mother as a mother of all vices and would not remove the brand; in this brief note I want to remove the brand of shame from laziness and to pronounce it not the mother of all vices, but the mother of perfection". Malevich, 1921.
This one is my favourite! I will just add that in the Spanish trabajo means "work" but also synonymously "trouble," for the Mexicans are wise. Maybe also the Spaniards.
