patient

The word 'patient' originates from the Latin verb pati, meaning "to suffer or endure." This root is traceable to the Proto-Indo-European stem pē(i)-, "to hurt," which also gives rise to words like 'passion' (originally "suffering") and 'pathos' (suffering, feeling). The Latin present participle patiens ("suffering, enduring") passed into Old French as pacient before entering Middle English. The semantic logic is clear: the adjective describes the quality of enduring hardship without complaint, while the noun originally meant "one who endures suffering," which narrowed specifically to a person enduring illness and receiving medical care.
