Humidity

HUMID'ITY

,
Noun.
Moisture; dampness; a moderate degree of wetness which is perceptible to the eye or touch, occasioned by the absorption of a fluid, or its adherence to the surface of a body. When a cloth has imbibed any fluid to such a degree that it can be felt, we call it humid; but when no humidity is perceptible, we say it is dry. Quicksilver communicates no humidity to our hands or clothes, for it does not adhere to them; but it will adhere to gold, tin and lead, and render them humid and soft to the touch.
1.
Moisture in the form of visible vapor, or perceptible in the air.
