inert

inert: [17] The -ert of inert is the same word as art. The word comes from Latin iners, which originally meant ‘unskilled’, but soon developed semantically to ‘inactive’. It was formed with the negative prefix in- from ars ‘skill’, source of English art. The derivative inertia [18] is a Latin formation. In classical times it meant simply ‘lack of skill, idleness’; it was Johannes Kepler who first used it as a technical term in physics in the 17th century.
