Morphology

hyperextension = extension (semi-transparent) = hyper + extend + tion

The word is built transparently from 'hyper' + 'extension', but the sense is specialized to abnormal bodily movement and injury risk.

Etymology

The word hyperextension is made of hyper- meaning 'over' and extension (from extend) meaning 'to stretch out'. So a hyperextension is when a joint or limb is stretched 'too far' or 'beyond' its normal range, which can cause injury.
