Morphology

retardation = retard (transparent) = retard + ation

The noun is a regular nominalization of the verb 'retard' meaning 'to slow', so the meaning 'process/result of slowing or delaying' follows directly.

Etymology

Retardation comes from old Latin parts re- ('back') and tardus ('slow') and is related to the English word tardy. So retardation means the process of making something slow or delaying its progress.
