self-caused slowing
Etymology
'autoretardation' is a modern English formation combining the prefix 'auto-' (from Greek 'autos' meaning 'self') with 'retardation' (from French/Latin roots) where 'retard-' meant 'to make slow'.
'retardation' comes from Old French 'retarder' and Latin 'retardare' ('re-' + 'tardare' meaning 'to make slow'); the compound 'autoretardation' is a later English coining using the Greek-derived prefix 'auto-' + the existing noun 'retardation'.
Initially, 'retardation' meant 'the act or effect of making slow'; through scientific usage the compounded form 'autoretardation' has come to denote specifically a self-induced slowing process observed in technical contexts.
