Root Explanation

Infusorian → It is formed from "infusorium" (from Latin *infusorium*, meaning a thing poured in) and the suffix "-an" (meaning pertaining to). The term refers to organisms that are typically found in infusions of organic matter, hence the connection to being 'pertaining to' these microscopic creatures.

Memory Tip

Think of 'infusorium' as something that is 'poured in' — this helps you remember that 'infusorian' refers to organisms related to those found in infusions.
