Etymology: "Aeration" is formed in English from the noun "aer" (Latin for air, borrowed from Greek "aēr") plus the suffix "-ation," which turns a verb into a noun of action. Its verb, "aerate," was built on the same base and means to supply something with air, whether by mixing gas into a liquid or by loosening soil so air can reach its roots. The word is a plain English formation rather than an inherited classical term, so its history is mostly one of technical use. The "aer" element appears in many scientific coinages, such as "aerobic," "aeroplane," and "aerosol," which were built from Greek and Latin roots in the 18th and 19th centuries, and "aeration" follows the same pattern.

Synonyms: ventilation, oxygenation
