insensitivity
UK: ɪnˌsɛnsɪˈtɪvɪti | US: ɪnˌsɛnsəˈtɪvəti
n. lack of sensitivity or responsiveness to emotions, physical sensations, or social cues
n. inability to perceive or react to subtle changes or stimuli
The word "insensitivity" originates from the Latin prefix in- (meaning "not") combined with sensitivus (from sentire, "to feel"), and the noun-forming suffix -ity. The root sensitive evolved through Old French (sensitif) and Latin (sensitivus), retaining its core meaning of "perceiving or reacting to stimuli." The addition of in- negates this quality, creating a term for emotional or physical unresponsiveness. The suffix -ity solidifies it as an abstract noun.
