IPA: //nɒn.əˈdæp.tɪv//
KK: /nɑnəˈdæptɪv/
Not able to change or adjust to new conditions or environments.
Some species are nonadaptive and cannot survive in changing climates.
Nonadaptive → It is formed from "non-" (meaning not) and "adaptive" (from Latin "adaptare", meaning to adjust or fit). The word "nonadaptive" means not able to adjust or fit to new conditions or environments.
Think of 'not' ('non-') being combined with 'adjusting' ('adaptare') — that's why nonadaptive means unable to adjust.
