What does insensibility mean?
Insensibility is a formal noun meaning either a lack of sensitivity or sympathy toward other people or the absence of physical sensation. In its figurative sense, it describes behavior that appears indifferent to suffering, injustice, criticism, or the needs of others, and it generally implies moral criticism rather than simple calmness or detachment. Its literal sense is associated with unconsciousness or a temporary inability to feel pain or other sensations. The word belongs mainly to formal, serious contexts and is less common in everyday speech than insensitivity. Etymologically, it was formed in English from the Latin prefix in-, meaning “not,” and sensibility, a word based on the Latin root sentire, “to feel, perceive, or sense.” Its historical connection with sensation makes it especially effective when describing both inability to feel physically and unwillingness to respond to others' feelings.
