impaired

the word 'impaired' is built upon the verb 'impair', which entered english in the late 14th century from old french 'empeirier', meaning 'to make worse'. this old french term derived from vulgar latin 'impeiorare', a combination of the latin prefix 'in-' (here, an intensifier meaning 'thoroughly') and 'peiorare' (to make worse), from 'peior' (worse). the core concept of worsening or deterioration is preserved from its latin ancestor. the addition of the '-ed' suffix transforms the action of the verb into an adjective describing the resulting state, leading to the modern meaning of being in a weakened or damaged condition.
