attitude: [17] In origin, attitude is the same word as aptitude. Both come ultimately from late Latin aptitūdō. In Old French this became aptitude, which English acquired in the 15th century, but in Italian it became attitudine, which meant ‘disposition’ or ‘posture’. This was transmitted via French attitude to English, where at first it was used as a technical term in art criticism, meaning the ‘disposition of a figure in a painting’. The metaphorical sense ‘mental position with regard to something’ developed in the early 19th century. => aptitude[attitude etymology, attitude origin, 英语词源]
