A Hausa purpose clause presents an event as the intended goal of another event. Its most useful frame is domin/don + subjunctive clause: Na kunna fitila domin yara su gani “I switched on a light so that the children could see.” English may hide the second subject inside an infinitive—to see, to buy, to help—but Hausa normally states the subject again in the preverbal subjunctive marker.
All unlabelled forms here are (neutral Nigerian Standard Hausa). Domin is the full form and is natural in both speech and careful prose; don is its common shorter form (neutral/conversational). This page explains the clause pattern, not the grade-specific stem shapes of individual verbs.
The purpose frame and its complete paradigm
The affirmative structure is:
main clause + domin/don + [noun subject, if expressed] + subjunctive marker + verb
The subjunctive marker is short and low-toned in speech. Ordinary boko does not write tone or vowel length, so the table gives standard unmarked spellings.
| Intended actor | Marker | Purpose-clause pattern |
|---|---|---|
| 1st singular | in | domin in yi aiki |
| 2nd masculine singular | ka | domin ka zo da wuri |
| 2nd feminine singular | ki | domin ki zo da wuri |
| 3rd masculine singular | ya | domin ya rubuta saƙo |
| 3rd feminine singular | ta | domin ta rubuta saƙo |
| 1st plural | mu | domin mu yi aiki |
| 2nd plural | ku | domin ku zo da wuri |
| 3rd plural | su | domin su rubuta saƙo |
| impersonal | a | domin a gyara hanya |
Na zo da wuri domin in yi magana da manaja.
I came early so that I could speak with the manager.
Ta ajiye mana abinci don mu ci idan mun dawo.
She set food aside for us so that we could eat when we returned.
Sun buɗe tagogin domin a sami iska.
They opened the windows so that there would be some air.
The purpose event is dependent: it is wanted or aimed at, not independently asserted as a fact. Nothing in mu ci guarantees that we actually ate. This non-asserted, prospective relation is why Hausa selects the subjunctive.
The subject remains visible even when it is the same
English says Amina went to the market to buy vegetables. The infinitive to buy does not repeat Amina. Hausa repeats her agreement in ta:
Amina ta je kasuwa domin ta sayi kayan lambu.
Amina went to the market to buy vegetables.
Musa ya rage gudu don ya guje wa ramin da ke hanya.
Musa slowed down so that he could avoid the pothole in the road.
When the intended actor is different, it can be named overtly. The noun does not replace the marker:
Na kunna fitilar domin yaran su karanta da kyau.
I switched on the lamp so that the children could read properly.
Here yaran is the overt plural subject and su is the required plural subjunctive marker. The form is not domin yaran karanta. Hausa places person, number, mood, and agreement before the lexical verb even when the actor is already named.
The same principle applies to a singular noun subject:
Mun tanadar da kujera domin Hajiya Binta ta zauna a gaba.
We provided a chair so that Hajiya Binta could sit at the front.
Purpose is not the same as reason
Saboda, domin, and don can occur in expressions translated with English because or for, so meaning matters. A purpose is an intended later result; a reason is presented as an explanation or cause that already holds. Compare:
Ta je asibiti domin ta ga likita.
She went to the hospital in order to see a doctor. (purpose)
Ta je asibiti saboda tana jin ciwo.
She went to the hospital because she was in pain. (reason)
The first ta ga is subjunctive: seeing the doctor is the goal of going. The second tana jin ciwo is continuative: her pain is presented as the reason for going. Do not choose the subjunctive simply because English contains because, for, or to. Ask whether the clause names an intended outcome.
With third-person singular subjects, ordinary boko can hide this contrast: subjunctive ta ga “so that she would see” and completive ta ga “she saw” have different pronunciation but the same unmarked spelling. Context therefore matters especially with domin/don, which can also introduce a cause. Other persons make the grammatical contrast visible in writing: purpose mu gaji “so that we would become tired” versus completive mun gaji “we became/were tired.”
Purpose also differs from a future prediction:
Na kira shi domin ya zo gobe.
I called him so that he would come tomorrow. (intended result)
Na san zai zo gobe.
I know that he will come tomorrow. (future proposition)
In the first sentence, ya zo is licensed by purpose. In the second, zai zo predicts a future event. English would in the first translation does not turn the Hausa form into a past tense.
Time comes from context, not an English tense label
The subjunctive does not locate an event on a calendar by itself. Time adverbs and the main clause establish the reference point:
Jiya na aika masa saƙo domin ya zo da yamma.
Yesterday I sent him a message so that he would come in the evening.
Gobe zan aika masa saƙo domin ya zo da yamma.
Tomorrow I will send him a message so that he can come in the evening.
The same ordinary written form ya zo can receive English would come in a past frame or can come in a future frame. Hausa has not changed the lexical verb to match those English tense choices. The first clause and adverbs jiya, gobe, da yamma do the temporal work. For the broader system, see aspect rather than English tense.
There is no relative subjunctive counterpart
The subjunctive has one subject-marker series; it does not alternate between a plain and a relative paradigm. A focused phrase or constituent question in a surrounding clause may trigger a relative completive or continuative form, but the embedded purpose clause remains subjunctive.
Me kake yi domin ka ƙara ƙarfi?
What are you doing in order to get stronger? (to a male)
Kake is relative continuative because me is questioned in the main clause. Ka ƙara is the masculine singular subjunctive inside the purpose clause. It is not a relative form and it is not past tense. See plain and relative TAM forms for the constructional contrast.
Negative purpose: avoiding an outcome
To express “so that … not” or “lest,” put kada before the entire subjunctive clause. Do not add the ordinary ba … ba frame.
Ta rufe abincin domin kada ƙudaje su sauka a kai.
She covered the food so that flies would not land on it.
Na rubuta lambar a takarda don kada in manta da ita.
I wrote the number on paper so that I would not forget it.
With an overt noun, the order is kada + noun + agreeing marker: kada ƙudaje su…. The shorter kar is common (informal/conversational), but full kada is especially clear in a longer dependent purpose clause. Neither form takes final ba.
Active and stative predicates under purpose
An active verb describes an intended action: domin ya buɗe shago “so that he opens the shop.” A stative predicate presents a desired state or a transition into one:
Na yi masa bayani a hankali domin ya san abin da ya faru.
I explained it to him slowly so that he would know what happened.
The subjunctive does not make san an action verb; it places the state of knowing inside the intended outcome. English may choose would know, could understand, or another context-sensitive rendering. The active–stative distinction affects interpretation, while the preverbal marker still carries the mood relation.
Practice
Complete each idea with a full purpose clause, then compare the model.
- “We saved money in order to buy a new pump.” Model: Mun ajiye kuɗi domin mu sayi sabon famfo.
- “She spoke loudly so that everyone could hear.” Model: Ta yi magana da ƙarfi domin kowa ya ji.
- “They locked the gate so that the goats would not get out.” Model: Sun kulle ƙofar gida domin kada awaki su fita.
- In Me kuke yi domin ku gama yau?, identify the forms: kuke is relative continuative in the question; ku gama is plural subjunctive in the purpose clause.
Common Mistakes
1. Dropping the subjunctive marker after the same subject
❌ Amina ta je shago domin sayi madara.
Incorrect — the purpose clause needs its own subject–TAM marker.
✅ Amina ta je shago domin ta sayi madara.
Amina went to the shop to buy milk.
2. Dropping agreement after an overt noun
❌ Na buɗe littafin domin yara karanta.
Incorrect — yara must be followed by plural subjunctive su.
✅ Na buɗe littafin domin yara su karanta.
I opened the book so that the children could read.
3. Using future za merely because English says will or would
❌ Na aika masa saƙo domin zai zo gobe.
Incorrect for the intended-purpose reading — zai presents a future proposition instead of the regular purpose subjunctive.
✅ Na aika masa saƙo domin ya zo gobe.
I sent him a message so that he would come tomorrow.
4. Treating a reason as a purpose
❌ Mun kwanta domin mu gaji.
Incorrect for ‘We lay down because we were tired’ — mu gaji presents becoming tired as the purpose of lying down.
✅ Mun kwanta saboda mun gaji.
We lay down because we were tired.
5. Adding ba to negative purpose
❌ Na ɓoye takardar domin kada yara su yage ta ba.
Incorrect — negative subjunctive kada does not take closing ba.
✅ Na ɓoye takardar domin kada yara su yage ta.
I hid the paper so that the children would not tear it.
Key Takeaways
- Build purpose with domin/don + subjunctive subject marker + verb.
- Repeat the marker even when the purpose actor is already the subject of the main clause.
- An overt noun still requires agreement: domin yaran su…, domin Amina ta….
- Purpose presents an intended result; a reason presents an explanation that holds.
- Time comes from the surrounding frame and adverbs, not from changing the subjunctive into an English-style tense.
- Negative purpose uses domin/don kada + subjunctive and never adds final ba.
