'vibration-reducing' is a modern English compound of 'vibration' and the present-participle form 'reducing' (from the verb 'reduce'). 'vibration' originates from Latin, specifically the word 'vibratio' (from 'vibrare'), where 'vibrare' meant 'to shake'. 'reduce' originates from Latin 'reducere', where the prefix 're-' meant 'back' or 'again' and 'ducere' meant 'to lead'.

'vibration' came into English via Latin 'vibratio' through Late Latin and Medieval Latin and developed into the English 'vibration'. 'reduce' came from Latin 'reducere' to Old French/Medieval Latin forms and entered Middle English as 'reducen'/'reduce', with the present participle forming 'reducing'. The compound 'vibration-reducing' is a straightforward modern English formation combining these elements.

Initially the element 'vibration' referred to the action or state of shaking and 'reduce' to lead back or lessen; combined in modern usage the compound came to mean 'serving to lessen shaking' and has retained that literal compositional meaning.
