IPA: /nɒnˈɪndɪdʒɪnəs/
KK: /nɑnˈɪndɪdʒənəs/
Referring to species or people that are not originally from a particular area or environment.
The nonindigenous plants in the garden can sometimes outcompete the local species.
Nonindigenous → It is formed from "non-" (meaning not) and "indigenous" (from Latin "indigenus", meaning native or born in a place). The word "nonindigenous" refers to something that is not native to a particular place or environment.
Think of 'non-' meaning 'not' and 'indigenous' meaning 'native' — so nonindigenous describes something that is not native.
