The word "precip" is a shortened form of precipitation, which refers to the falling of moisture from the atmosphere. The antonym of "precip" would be words that denote the opposite of precipitation, such as evaporation, condensation, and sublimation. These processes refer to the conversion of moisture from a gaseous state to a solid or liquid state or vice versa. Evaporation is the conversion of liquid to gas, while condensation is the reversal of this process. Sublimation refers to the conversion of a solid directly into a gas. These antonyms describe the different ways in which moisture can move through the atmosphere, leading to changes in weather patterns and climate.
