IPA: /nɒnˈfɪzɪkəl/
KK: /nɑnˈfɪzɪkəl/
Something that does not have a physical form or is not related to the physical world.
The concept of love is often considered nonphysical, as it cannot be touched or seen.
Nonphysical → It is formed from "non-" (meaning not) and "physical" (from Greek "physikos", meaning natural or relating to nature). The word "nonphysical" means not relating to the physical or material world.
Think of 'not' ('non-') relating to the 'natural' or 'material' world ('physikos') — that's why nonphysical refers to things that are not material.
