Right flesh radical — visually
月 but historically the contracted
肉. Anchors
胡 in body-parts vocabulary: the original lexical sense was 'jowl, dewlap, hanging flesh under the chin,' from which came
胡子 (beard, whiskers) and by extension 'reckless, careless' (loose like a dewlap). Same radical in
脸 (face),
肤 (skin),
肠 (intestine).
