avant que

• IPA^(key): /a.vɑ̃ kə/

avant que (+ subjunctive)

1. before

   Antonym: après que

• Along with en attendant que (“until”) and jusqu'à ce que (“until”), avant que is one of the three conjunctions of time that take the subjunctive in prescriptive French; all three refer to expected events in the future. Colloquially, après que may also take the subjunctive, but this is discouraged by language authorities.
• In written French, the verb that follows avant que takes the "expletive" particle ne, which does not negate the verb and serves no grammatical function.
