1. Shame, embarrassment, mortification, humiliation, chagrin designate different kinds or degrees of painful feeling caused by injury to one's pride or self-respect. Shame is a painful feeling caused by the consciousness or exposure of unworthy or indecent conduct or circumstances: One feels shame at being caught in a lie. It is similar to guilt in the nature and origin of the feeling.

Mortification is a more painful feeling, akin to shame but also more likely to arise from specifically social circumstances: his mortification at being singled out for rebuke. Humiliation is mortification at being humbled in the estimation of others: Being ignored gives one a sense of humiliation.
