Why have we chosen à priori? You'll hear this French expression used in everyday conversation and it's one that's likely to sound particularly strange if you don't already know it. You'll also see it used fairly regularly in French headlines. This expression actually has Latin origins and while it is used a lot in French, in English its usage is largely restricted to philosophy and statistics. Depending on the context, it can be used to mean 'in principle', 'if everything goes as planned' and 'unless something changes'.
