The term "heboid paranoia" is a rare medical diagnosis that refers to a form of delusional disorder in which an individual experiences irrational and unfounded beliefs related to persecution and conspiracy. The term is spelled as /ˈhiː.bɔɪd pær.əˈnɔɪ.ə/ in IPA phonetic transcription. The term "heboid," which denotes a resemblance to Hebrew people, is followed by "paranoia," which refers to an extreme form of suspicion and distrust.
