IPA: /ˈniːpæd/
KK: /ˈniːˌpæd/
A protective item worn on the knee to prevent injury or provide comfort during activities like kneeling.
He wore a kneepad while working on the floor to protect his knees.
Kneepad → It is formed from "knee" (from Old English "cneow", meaning the joint between the thigh and the lower leg) and "pad" (from Old English "pædd", meaning a cushion or soft covering). A kneepad is a soft covering designed to protect the knee joint.
Think of the 'knee' as the joint that needs protection and 'pad' as a soft covering — that's why a kneepad is a protective cushion for the knee.
