'amortisseur' originates from French, specifically the word 'amortir,' where 'a-' meant 'to' and 'mortir' meant 'to deaden or dampen.'

'amortir' transformed into the French word 'amortisseur,' and eventually became the modern English word 'amortisseur' through borrowing.

Initially, it meant 'to deaden or dampen,' and this meaning has largely remained the same in modern usage.
