noun
Dated term for a foolish or stupid person. Not commonly used in modern conversation; may appear in historical or literary contexts.
あの男はまったくの痴れ者だ。
That man is a complete fool.
Compound of 痴れ (shire, the 連用形 of classical verb 痴る 'to be foolish') + 者 (mono, 'person'). The exact historical derivation is uncertain, but the spelling is conventionally associated with foolishness.
