Requiring no exertion; effortless or done without effort or strain.
From exertion + -less suffix. Exertion comes from Latin exertus (thrust out), and -less is a Germanic suffix meaning 'without,' making this a modern compound.
The word 'exertionless' is wonderfully paradoxical—we use it to praise things (like 'exertionless elegance'), yet exertion is what builds strength, so truly exertionless living would leave you weak.
