Origin

Late Middle English: from Old French positif, -ive or Latin positivus, from posit- 'placed', from the verb ponere. The original sense referred to laws as being formally 'laid down', which gave rise to the sense 'explicitly laid down and admitting no question', hence 'certain'.

At the core of positive is the idea of placing something firmly, and the ultimate source is Latin ponere ‘to place’. In the 14th century the English word was used to refer to laws as being formally laid down. From this developed the more general meaning ‘explicitly laid down and admitting no question’ (as in proof positive), and later ‘very sure, convinced’. Position (Late Middle English) comes from the same root, as does postpone (late 15th century) literally ‘place after’. See also compost, post
