passion: [12] Latin patī meant ‘suffer’ (it is the source of English patient). From its past participial stem pass- was coined in postclassical times the noun passiō, denoting specifically the ‘suffering of Christ on the cross’. English acquired the word via Old French passion, but its familiar modern senses, in which ‘strength of feeling’ has been transferred from ‘pain’ to ‘sexual attraction’ and ‘anger’, did not emerge until the 16th century. Also from the Latin stem pass- comes passive [14], etymologically ‘capable of suffering’. => passive, patient[passion etymology, passion origin, 英语词源]
