 In·ert a.
 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.   --Macaulay.
    It present becomes extravagant, then imbecile, and 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.

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

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