The process of converting something into air or gas, or infusing something with air.
From Latin aer (air) plus facere (to make), plus -tion. This technical term literally means 'air-making' and emerged in scientific contexts.
Aerifaction was crucial in 19th-century water treatment and carbonation processes—it's how they figured out how to bubble gas through liquids to preserve them, eventually leading to soda and modern beverage manufacturing.
