Etymology
the word 'conversely' is built upon the adjective 'converse', which originates from the latin verb 'convertere', meaning 'to turn around' or 'to transform'. this verb itself is a compound of 'con-' (an intensive prefix meaning 'altogether') and 'vertere' (meaning 'to turn'). the adverbial suffix '-ly', of germanic origin, was attached to form a word meaning 'in a converse manner'. thus, the literal sense of 'turned about' evolved into the modern abstract meaning of expressing an opposite or reversed relationship between two ideas or facts.
