Cognate: 5422 phrenapatáō (from 5424 /phrḗn, "inner-outlook regulating behavior" and 538 /apatáō, "deceive by distorting") – properly, to act from a distorted perspective (warped sense of reality) which "redefines reality" (facts) – i.e. to fit one's self-deception (used only in Gal 6:3). See 5423 (phrenapatēs).

5422 /phrenapatáō ("confused inside-out") means to become the victim of one's own confused mind-set – which then blames God for it or makes others "the scapegoat." This mind-set is detached from reality and leaves someone in their own fantasy world.

"More is implied in this word (5422 /phrenapatáō) than in apataō ('to cheat, beguile, deceive'), for it brings out the idea of subjective fancies" (J. Thayer). This term was apparently "coined by Paul" (N. Turner).
