From the verb 'impair' + the noun-forming suffix '-ment'. 'Impair' comes from Old French 'empeirier' (to make worse), from 'im-' (in) + Latin 'peior' (worse).

Think of 'im-' as 'not' and 'pair' as in a perfect pair. An 'impairment' means something is 'not a perfect pair', i.e., it's damaged or weakened.
