IPA: /hɪpˈnɔɪdəl/
KK: /hɪpˈnɔɪdəl/
Relating to a state that resembles hypnosis or is similar to it.
The hypnoidal state can be used for therapeutic purposes.
Hypnoidal is formed from "hypnos" (meaning sleep) and the suffix "-oid" (meaning resembling or like). The word describes something that resembles or is related to sleep.
Think of 'hypnos' as relating to sleep, and '-oid' meaning like or resembling — so hypnoidal refers to something that is like sleep.
