🌱 Where it comes from

The word insensible traces back to the 14th century, from the Latin prefix 'in-' meaning 'not' and 'sensibilis' meaning 'perceptible by the senses'. Its original meaning was 'incapable of being felt', which then expanded to describe a person who is incapable of feeling, either because they are unconscious or because they are emotionally unfeeling.
