Etymology
the word 'induration' originates from the latin verb 'indurare', meaning "to make hard". this verb itself is a compound of the prefix 'in-', signifying "into" or "upon", and the adjective 'durus', meaning "hard". the root 'durus' is traced back to the proto-indo-european base 'deru-/dreu-', which conveys notions of firmness and solidity, also giving rise to words like 'tree' and 'true'. through medieval latin 'induration-', the term entered english in the late 14th century, initially describing a spiritual hardening of the heart before its medical application to the physical hardening of tissues.
