Act #17: ADN

Today’s expression comes directly from Latin. While the Latin phrase a priori is used in English in certain domains such as philosophy and statistics, in French it's part of everyday language. It literally translates "from the earlier".

Normally, a priori means "at first glance", "in principle", "upon initial consideration". It can also be equivalent to "should", as in example 2, meaning that if things go as expected, xyz should happen. In the third example, a priori indicates that a refusal was made without any consideration of a request or suggestion.
