Noninfested → It is formed from "non-" (meaning not) and "infested" (from Latin "infestare", meaning to attack or invade). The word "noninfested" means not being attacked or invaded by pests or harmful organisms.
Think of 'non-' meaning not, and 'infested' meaning attacked or invaded. This helps you remember that 'noninfested' refers to something that is not under attack or invasion.
