Etymology
'imperturbability' originates from Latin, specifically the word 'imperturbabilis' (from 'im-' + 'perturbare'), where 'im-' meant 'not' and 'perturbare' meant 'to disturb.'
'imperturbability' changed from the Medieval Latin 'imperturbabilitas' and through Old French/Medieval Latin usage entered Middle English as 'imperturbabilite', eventually becoming the modern English word 'imperturbability'.
Initially, it meant 'the quality of not being disturbed', and over time it evolved into its current meaning of 'unshakable calmness or composure.'
