Before and After Clauses | Farsi Grammar

Persian uses قبل از اینکه “before” and بعد از اینکه “after” before finite clauses. These connectors make the order of two events explicit even when the clauses appear in reverse narrative order. The embedded verb still expresses person, tense, and mood.

When the two events share a subject, Persian can often use the shorter قبل از / بعد از + infinitive. With different subjects, the finite اینکه clause is normally clearer because it identifies who performs the embedded event. Review the nominal behavior of this form in Long Infinitives as Verbal Nouns.

Construction map

Relation	Different or explicit subject	Shared-subject alternative	Tendency
before	قبل از اینکه + finite clause	قبل از + infinitive	prospective event favors subjunctive
after	بعد از اینکه + finite clause	بعد از + infinitive	completed event favors past/perfect

قبل از اینکه مهمان‌ها برسند، میز را آماده می‌کنیم.

qabl az in-ke mehmân-hâ be-rasand, miz râ âmâde mi-konim.

Before the guests arrive, we will prepare the table. (neutral; different subject and prospective subjunctive)

بعد از اینکه جلسه تمام شد، همه به کافه رفتند.

ba'd az in-ke jalase tamâm shod, hame be kâfe raftand.

After the meeting ended, everyone went to a café. (neutral; completed sequence)

Before: an event not yet realized

Because the “before” event is still pending at the reference point, an open future clause commonly uses the subjunctive.

قبل از اینکه تصمیم نهایی را بگیری، با وکیل مشورت کن.

qabl az in-ke tasmim-e nehâyi râ be-giri, bâ vakil mashverat kon.

Before you make the final decision, consult a lawyer. (neutral advice; prospective subjunctive)

پیش از آنکه هوا تاریک شود، باید به روستا برسیم.

pish az ân-ke havâ târik shavad, bâyad be rustâ be-rasim.

Before it gets dark, we must reach the village. (formal/literary-neutral variant پیش از آنکه)

The second connector is more formal; ordinary conversation prefers قبل از اینکه. Careful standard Persian normally keeps the subjunctive even in past narratives: قبل از اینکه بیاید، زنگ زد. Some colloquial speakers align the embedded verb with a completed narrative, but learners should not use that as the default.

💡

The subjunctive after “before” reflects nonrealization at the reference point, not a rigid rule attached to the connector. Past narrative viewpoint can change the choice.

After: a completed anchor

“After” normally anchors the main event to an already completed event, so simple past or perfect forms are common.

بعد از اینکه گزارش را فرستادم، متوجه یک اشتباه شدم.

ba'd az in-ke gozâresh râ ferestâdam, motavajjeh-e yek eshtebâh shodam.

After I sent the report, I noticed an error. (neutral past sequence)

بعد از اینکه دارو را خورده‌ای، نیم ساعت استراحت کن.

ba'd az in-ke dâru râ khorde-i, nim sâ'at esterâhat kon.

After you have taken the medicine, rest for half an hour. (neutral instruction; completion emphasized)

Completion is relative to the main event, not necessarily to speech time. A future “after” clause is still nonactual and can therefore use the subjunctive, as in بعد از اینکه با مدیر صحبت کنم below.

Infinitive alternatives

When no participant is expressed, قبل از رفتن and بعد از رسیدن package the event as a verbal noun, and the main-clause actor is normally understood as its actor. Formal nominalizations can instead name a participant through ezâfe, as in پس از ورود رئیس “after the director’s arrival,” but a finite clause is clearer for beginners when two actors could compete.

قبل از خروج پنجره‌ها را ببندید.

qabl az khoruj panjare-hâ râ be-bandid.

Before leaving, close the windows. (formal instruction; nominalized event)

بعد از رسیدن به هتل، مستقیم خوابیدیم.

ba'd az rasidan be hotel, mostaqim khâbidim.

After reaching the hotel, we went straight to sleep. (neutral; shared subject we)

If an unexpressed participant could accidentally inherit the wrong main subject, restore a finite clause. A formal event nominal with an ezâfe participant is a separate compact option.

بعد از اینکه تاکسی رسید، ما وسایل را پایین بردیم.

ba'd az in-ke tâksi rasid, mâ vasâyel râ pâ'in bordim.

After the taxi arrived, we took the luggage downstairs. (different subjects made explicit in a finite clause)

💡

With no expressed participant, use the infinitive when one actor controls both events. A finite clause is clearest when the embedded event has its own subject; formal nominalizations such as پس از ورود رئیس are a separate compact option.

Clause position

The temporal clause can lead and frame the sequence, or follow as background information.

به تو خبر می‌دهم بعد از اینکه با مدیر صحبت کنم.

be to khabar mi-daham ba'd az in-ke bâ modir sohbat konam.

I'll let you know after I speak with the manager. (neutral; main promise foregrounded)

Common Mistakes

❌ قبل از اینکه مهمان‌ها رسیدن، غذا را گرم کن.

Incorrect — رسیدن is an infinitive inside a finite different-subject clause.

✅ قبل از اینکه مهمان‌ها برسند، غذا را گرم کن.

qabl az in-ke mehmân-hâ be-rasand, ghazâ râ garm kon.

Before the guests arrive, warm the food.

❌ بعد از اینکه جلسه تمام، بیرون رفتیم.

Incorrect — the اینکه clause needs a finite predicate.

✅ بعد از اینکه جلسه تمام شد، بیرون رفتیم.

ba'd az in-ke jalase tamâm shod, birun raftim.

After the meeting ended, we went outside.

❌ قبل اینکه از بروی، زنگ بزن.

Incorrect — the connector is قبل از اینکه, and از cannot be stranded inside it.

✅ قبل از اینکه بروی، به من زنگ بزن.

qabl az in-ke be-ravi, be man zang be-zan.

Before you leave, call me.

❌ بعد از رسیدن تاکسی، ما رفت.

Incorrect — the main subject ما requires رفتیم, not رفت. The event nominal رسیدن تاکسی can itself name the taxi as its participant.

✅ بعد از اینکه تاکسی رسید، ما راه افتادیم.

ba'd az in-ke tâksi rasid, mâ râh oftâdim.

After the taxi arrived, we set off.

Key Takeaways

Use قبل از اینکه/بعد از اینکه + finite clause as the clearest default when the embedded subject differs.
“Before” commonly favors subjunctive for a still-unrealized event; “after” commonly anchors a completed event.
With one shared subject, قبل از/بعد از + infinitive is compact and natural; formal event nominals can also take an ezâfe participant.
Either temporal clause can come first; position controls framing, not basic chronology.
