The state of being unable to feel or respond to physical sensations or emotions.
His insensibility to the pain surprised everyone around him.
Insensibility → It is formed from "in-" (meaning not) and "sensibilis" (from Latin, meaning able to feel or perceive) and the suffix "-ity" (meaning the state or condition of). The word "insensibility" refers to the state of being unable to feel or perceive sensations.
Think of 'not' ('in-') being able to 'feel' ('sensibilis') — that's why insensibility means the condition of not being able to feel.
