Latin is a very precise language with very strict rules of grammar and meaning and few parallels with modern sloppy English (if you saw the episode of Time Team where they argued about how to translate the dodgy title of the show into Latin you will have some idea what I mean).
The word "bargain" for example has today come to mean a transaction where the buyer thinks they are getting something for less than they expected to pay - but the Latin term (pactio
) simply indicates an agreement, a compact, something agreed by bargaining, but generally without the modern marketing meaning. The plural "bargains" would be pactiones
The term "wonderful/amazing/marvellous/extraordinary things" would be res mirabiles
, which has a certain ring to it.
