IPA: /nɒnˈsɛnsɪtɪv/
KK: /nɑnˈsɛnsɪtɪv/
Not able to feel or respond to sensory stimuli; lacking sensitivity.
The material used in the construction of the building is nonsensitive to temperature changes.
Nonsensitive → It is formed from "non-" (meaning not) and "sensitive" (from Latin "sensitivus", meaning capable of feeling or perceiving). The word "nonsensitive" means not capable of feeling or perceiving, or not responsive to stimuli.
Think of 'not' ('non-') being added to 'sensitive', which means capable of feeling. This helps you remember that 'nonsensitive' refers to something that does not feel or respond.
