Root Explanation

Hallucinosis is formed from "hallucinari" (meaning to wander in the mind) and the suffix "-osis" (meaning a condition or process). The word describes a condition characterized by hallucinations or a wandering of the mind that leads to false perceptions.

Memory Tip

Think of 'wandering in the mind' ('hallucinari') leading to a 'condition' ('-osis') where one experiences false perceptions.
