Simplified etymology

Inertia entered English in the mid-16th century and derives from Latin iners, “unskilled” or “inactive.” Iners was formed as the opposite of ars, “skill,” giving inertia its underlying association with inactivity.

Etymology

From Latin inertia (“lack of art or skill, inactivity, indolence”), from iners (“unskilled, inactive”), from in- (“without, not”) + ars (“skill, art”). Something close to the modern physics sense was first used in New Latin by Johannes Kepler.
