Inert \In*ert"\, a. [L. iners, inertis, unskilled, idle; pref.
in- + ars art: cf. F. inerte. See {Art}.]
1. Destitute of the power of moving itself, or of active
resistance to motion; as, matter is inert.

2. Indisposed to move or act; very slow to act; sluggish;
dull; inactive; indolent; lifeless.

The inert and desponding party of the court.

at length utterly inert. --I. Taylor.

3. Not having or manifesting active properties; not affecting
other substances when brought in contact with them;
powerless for an expected or desired effect; as, the noble
gases are chemically inert.

Syn: Inactive; dull; passive; indolent; sluggish; slothful;
lazy; lifeless; irresolute; stupid; senseless;
insensible.

Usage: {Inert}, {Inactive}, {Sluggish}. A man may be inactive
from mere lack of stimulus to effort; but one who is
inert has something in his constitution or his habits
which operates like a weight holding him back from
exertion. Sluggish is still stronger, implying some
defect of temperament which directly impedes action.
Inert and inactive are negative, sluggish is positive.

Even the favored isles . . .
Can boast but little virtue; and, inert
Through plenty, lose in morals what they gain
In manners -- victims of luxurious ease.
--Cowper.

obscurity. --Johnson.

Sluggish Idleness, the nurse of sin,
Upon a slothful ass he chose to ride. --Spenser.
