Quick Summary

Aeration is the process of exposing something to air, or the act of supplying it with air. This can involve impregnating a substance, like soil or a liquid, with air. For example, blood is supplied with oxygen through respiration, which is a form of aeration. In some contexts, particularly in British English, aeration can also refer to carbonation or making something light and sparkling. The term originates from the Latin word for air.12
