IPA: /nɒnˈskɛtəl/
KK: /nɑnˈskɛtəl/
Relating to parts of the body that are not part of the skeleton.
The doctor explained the nonskeletal aspects of the injury.
Nonskeletal → It is formed from "non-" (meaning not) and "skeletal" (from Latin "skeletus", meaning dried up or skeleton). The word "nonskeletal" refers to something that is not related to or does not involve a skeleton.
Think of 'non-' meaning not, and 'skeletal' referring to a skeleton — so nonskeletal means not related to a skeleton.
