'Before', 'after', 'until': add 'que' when a whole clause follows
In English, words like before, after, until and since work in two ways. You can say before dinner or before you leave, and the word stays the same. French splits these into two forms. Before a noun you use the short word: avant le dîner. Before a full clause with its own subject and verb, you add que: avant que tu partes.
English speakers often forget this and say things like après je suis arrivé or jusqu'à je reviens. This article covers avant, après, jusqu'à, depuis, pendant and sans, and shows which verb form follows each que version.
Ask yourself what comes after the time word. If it is a noun, a date or a pronoun (le film, lundi, moi), use the short form. If it is a subject plus a conjugated verb (je reviens, il pleut), use the form with que. Before a vowel, que becomes qu': depuis qu'il est là.
There is one more thing to learn. Some of the que forms are followed by the subjunctive, and others by the normal indicative. This does not depend on the noun version at all, so learn whether each que form takes the subjunctive or the indicative.
- Subjunctive: avant que, jusqu'à ce que, sans que
- Indicative: après que, depuis que, pendant que
avant becomes avant que, followed by the subjunctive.
après becomes après que. In standard French it is followed by the indicative.
jusqu'à is the special one. It does not simply add que. It becomes jusqu'à ce que, followed by the subjunctive.
depuis becomes depuis que, followed by the indicative.
pendant becomes pendant que, followed by the indicative. English changes the word here too (during and while), but French keeps the same base word.
sans is not a time word, but it follows exactly the same pattern. It becomes sans que, followed by the subjunctive.
When both parts of the sentence have the same subject, French usually avoids the form with que and uses an infinitive instead. With avant you add de. With après you use the past infinitive (avoir or être plus a past participle). With sans you simply add the infinitive.
You will often hear après que followed by the subjunctive in everyday speech. It is very common, but the indicative is still the standard form. The most frequent real mistake, though, is leaving out que altogether. Never write jusqu'à je reviens or pendant je mange.
Before a noun, use the short word: avant, après, jusqu'à, depuis, pendant, sans. Before a subject and a verb, add que, and remember that jusqu'à becomes jusqu'à ce que. Use the subjunctive after avant que, jusqu'à ce que and sans que, and the indicative after après que, depuis que and pendant que. If the subject is the same in both parts, prefer an infinitive: avant de partir, après être parti, sans rien dire.
