ashamed
覥 centers on the feeling of shame or embarrassment, specifically being ashamed of one's own actions or appearance.
覥 is a phono-semantic compound combining 見 (see) with 典, which likely contributes the sound and may relate to a standard or rule, suggesting the shame of being seen against a standard.
The left side 典 suggests a rule or standard, and the right side 見 means see. Imagine being seen failing to meet a standard and feeling deeply ashamed.
For テン, picture ten people watching you make a mistake, and you feel ashamed: ten -> テン.
