Air that contains all the moisture that it can hold is known as saturated.

Explanation

Air tends to contain certain amount of water vapor along with other gas molecules.

The water vapors in air is termed as moisture. Each air molecule are able to hold discrete capacity of water vapors or moisture. This is generally termed as humidity.

The relation between the quantity of water vapor in the air molecule with the total quantity of water vapor can be contained in air molecule is termed as relative humidity.

When the relative humidity becomes 100% which means the air molecule have captured or contained the maximum moisture content it can hold, this point is termed as saturated point.

Thus the condition when the air holds the maximum moisture that's capable of containing is termed as saturated humidity or saturated condition of air molecules.
