prior to

Preposition

 * 1)  before, previous to.

Usage notes
The etymological antonym of is  (from Latin), and the corresponding antonym to prior to is  (compare / for “first/last”). This is now no longer used, however, and there is no corresponding antonym to express “after”. Typically either (to) or  (to) are used, but these form different pairs – / and / – and are more formal than. For this reason some suggest against using prior to, particularly when it is paired with an antonym, instead using the Germanic /.
