means Removing the outer husk or pod from nuts, seeds, or shellfish to get at the edible part inside.

from From 'shell,' tracing back to Old English 'sciell' / 'scealu,' meaning a husk, pod, or paring — itself related to a Germanic root meaning 'to split' or 'to cleave,' the same ancestor that gave us 'scale' and 'skill.' The idea has always been about dividing a tough outside from a soft inside — the verb 'to shell' just means doing that division on purpose, one stubborn pistachio at a time.
