'Shame' may trace to PIE 'to cover' — linking disgrace to the impulse to hide from others' gaze.
A painful feeling of humiliation or distress caused by consciousness of wrong or foolish behavior; disgrace.
From Old English 'scamu, sceamu' (feeling of disgrace, dishonor, loss of esteem), from Proto-Germanic *skamō (shame, disgrace), possibly from PIE *ḱam- or *skem- (to cover, to hide). The connection to covering is profound: shame is etymologically the impulse to hide oneself, to cover one's face or body. The Genesis narrative of Adam and Eve covering themselves after eating the forbidden fruit is shame in its etymological sense — the need to conceal. Key
The Scandinavian word 'skam' (shame) entered global pop culture through the Norwegian TV series 'Skam' (2015–2017), which became an international sensation. The show's title uses the exact Old Norse cognate of English 'shame' — a word virtually unchanged in meaning across a thousand years of Germanic language history.
