It means that the air is holding as much water vapor as it can at that temperature. Any increase in moisture or decrease in temperature at that point will result in water condensing.
Saturated air is air that has all the water vapor that it can hold.

When a paracel of air is cooled to the temperature at which it is saturated, it has reached its dew point.
Dew pointThe dew point is the temperature to which air must cool to be saturated.
When saturated air is warm, it creates an unstable air mass. As the moisture content rises, the humidity rises as well. This can lead to warm and humid conditions.
The temperature to which air must be cooled to become saturated.
Saturated air is air that has all the water vapor that it can hold.
Saturated air is air that has all the water vapor that it can hold.
Saturated air is more dense.
When a parcel of air is saturated with water vapor the relative humidity of that parcel of air is 100%.

When a paracel of air is cooled to the temperature at which it is saturated, it has reached its dew point.
If it is humid it is saturated. If it is dry it is unsaturated.
"Saturated" or "At saturation point".
Dew pointThe dew point is the temperature to which air must cool to be saturated.
