IPA: //nɒnˈɪn.sɛkt//
KK: /nɑnˈɪnˌsɛkt/
A creature that does not belong to the class of insects.
A spider is a noninsect, as it is an arachnid.
Noninsect → It is formed from "non-" (meaning not) and "insect" (from Latin "insectum", meaning cut into or divided). The word "noninsect" refers to organisms that are not classified as insects.
Think of 'non-' meaning not, and 'insect' referring to the divided creatures we call insects. This helps you remember that 'noninsect' means something that is not an insect.
