'rigidly-managed' originates from the combination of 'rigidly' and 'managed'. 'Rigidly' comes from the Latin word 'rigidus', meaning 'stiff', and 'managed' is derived from the Italian 'maneggiare', meaning 'to handle'.

'Rigidly' evolved from the Latin 'rigidus' through Old French 'rigide', and 'managed' evolved from the Italian 'maneggiare' through Middle English 'managen'.

Initially, 'rigidly' meant 'stiff or unyielding', and 'managed' meant 'to handle or control'. Together, they evolved to mean 'controlled in a strict manner'.
