Hausa has two structurally different ways to describe causation. An established Grade 5 verb packages cause and result as one lexical event: Malamai sun fitar da yaran “The teachers took the children out.” The analytic construction uses sa “put; cause” plus a second predication with its own subject marking: Malamai sun sa yaran su fita “The teachers got the children to go out.” The second construction is productive; Grade 5 derivation is lexically restricted.
For the classification behind that contrast, see what a Hausa verb grade is—and is not.
All unlabelled examples are (neutral Nigerian Standard Hausa). Ordinary boko writes no tone or vowel length. Sa here is the independent verb “put/cause,” not a suffix and not the conjunction sai.
One predicate versus two
The formal contrast explains much of the semantic contrast.
| Construction | Shape | Typical construal |
|---|---|---|
| Grade 5 | subject + TAM + derived verb + affected object | one compact, often direct or conventional event |
| analytic causative | subject + TAM + sa + embedded subject + TAM/predicate | one participant causes, induces, or brings about another event |
Mahaifiyar ta kwantar da jaririn a gadonsa.
The mother laid the baby down in his bed. (Grade 5; direct placement)
Uban ya sa yaron ya kwanta a kan tabarma.
The father got the boy to lie down on the mat. (analytic; the boy is subject of kwanta)
Mai gadin ya fitar da baƙon daga harabar.
The guard escorted the visitor out of the compound. (Grade 5)
Mai gadi ya sa baƙon ya fita daga ofis.
The guard made the visitor leave the office. (analytic)
In the Grade 5 clauses, jaririn/baƙon is the affected object of one transitive verb. In the analytic clauses, that participant is the grammatical subject of ya kwanta/ya fita. The analytic construction therefore preserves a fuller picture of the caused event.
Directness is a strong tendency, not a mechanical law
Grade 5 often presents direct manipulation or a conventional result: stopping a vehicle, laying a child down, removing an object, teaching a subject. The analytic construction more readily allows an order, pressure, arrangement, circumstance, or other mediated cause.
Jami’in ya tsayar da motar a wurin bincike.
The officer stopped the vehicle at the checkpoint. (one direct event)
Shugaban ’yan sanda ya sa jami’in ya tsayar da bas ɗin.
The police chief made the officer stop the bus. (the officer performs the stopping)
Ruwan sama ya sa mun dawo gida da wuri.
The rain made us return home early. (a circumstance causes the event)
The rain does not manipulate the speakers physically. Sa relates a causing situation to the proposition mun dawo gida da wuri. This productivity is exactly what Grade 5 lacks: speakers do not need to coin a special derived verb for “rain-caused returning.”
Directness is a semantic prototype, not a rule that guarantees one construction in every context. Established Grade 5 verbs such as sayar “sell” and koyar “teach” are conventional lexical items. Their meanings cannot be recovered only from physical directness.
Grade 5 has lexical gaps; sa is productive
Only use a Grade 5 form that belongs to actual Hausa vocabulary. Tsayar, fitar, kwantar, koyar, sanar, sayar are established. The fact that a root can be imagined with -ar does not show that speakers commonly use it or that its meaning would be predictable.
Shugabar ta sa ma’aikata sun sake rubuta rahoton.
The chairwoman had the staff rewrite the report. (productive analytic causative)
Sakamakon ya sa mutanen sun yi shiru.
The result made the people fall silent.
The lower predicate can be complex: sun sake rubuta rahoton includes plural agreement, completive aspect, sake “again,” and its own object rahoton. Grade 5 is not a productive replacement for such a clause.
English speakers sometimes assume the opposite because English also has lexical pairs (lie/lay, learn/teach) beside productive make. Hausa makes the same broad distinction, but the membership and syntax of the lexical set are specifically Hausa and must be learned.
The lower predication carries its own grammar
After causal sa, state the caused participant and mark it as the subject of the second predicate. The neutral induced-event pattern normally uses the subjunctive: in, ka, ki, mu, ku, ya, ta, su, a plus the verb. In past-time contexts with a perfective matrix verb, a perfective lower clause is also possible when the speaker presents the result as actually realized; an imperfective can profile a maintained situation. The lower predicate is therefore not simply an English bare infinitive.
Ta sa ni in karanta takardar sau biyu.
She made me read the document twice. (neutral subjunctive lower predicate)
Abin da ya faru ya sa mun canja shirinmu.
What happened made us change our plan. (perfective lower result presented as realized)
Sun sa yaran suna jira a waje.
They kept the children waiting outside. (continuative lower situation)
Kar ka sa yaran su yi jinkiri.
Do not make the children be late / Do not delay the children. (negative directive)
In ta sa ni in karanta, ni is the causee and the understood subject of the lower predicate, while in supplies its first-person singular subjunctive marking. With a lexical Grade 5 verb, by contrast, the affected participant is directly inside that verb’s object frame.
Grade 5 object frames stay inside one verb
Take tsayar “halt” through the four environments:
| Environment | Grade 5 example |
|---|---|
| no following object | Jami’in ya tsayar. |
| noun direct object | Jami’in ya tsayar da motar. |
| direct-object pronoun | Jami’in ya tsayar da ita. |
| indirect object | Jami’in ya tsayar masa da motar. |
The long Grade 5 construction uses da + noun/independent pronoun. Its indirect object masa can mark a beneficiary or affected party. None of these creates a second event with its own subject.
Now compare Jami’in ya sa direban ya tsayar da motar. The analytic construction contains the full Grade 5 clause direban ya tsayar da motar as the caused situation. The two strategies can therefore nest; they are not competing spellings of one ending.
Meaning changes when participant roles change
Compare the following carefully:
Malam ya koyar da ɗalibai Hausa.
The teacher taught the students Hausa. (lexical Grade 5 koyar)
Malam ya sa ɗalibai sun koyi sabbin kalmomin.
The teacher got the students to learn the new words. (analytic result)
The first foregrounds teaching as an activity. The second foregrounds the students’ learning event and presents the teacher as its causer. Both may describe the same real-world lesson, but they organize it differently.
Similarly, ya sanar da ɗaliban labarin means “he informed the students of the news”; ya sa ɗaliban sun san labarin is not a routine substitute meaning simply “he informed them.” The analytic expression claims that his action caused their state of knowing and may sound appropriate only in a context that supports that causal chain.
Practice: choose the viewpoint
Use Grade 5 for a compact established event: “The nurse laid the patient down” → Ma’aikaciyar jinya ta kwantar da marar lafiya. Use analytic sa when the caused participant retains a distinct action: “The nurse got the patient to lie down” → Ma’aikaciyar jinya ta sa marar lafiya ya kwanta. For an inanimate cause, choose the analytic construction: “The heat made us leave” → Zafin ya sa mun tafi.
Common Mistakes
1. Treating the two constructions as exact paraphrases.
❌ Ta kwantar da jaririn koyaushe daidai yake da ta sa jaririn ya kwanta.
Incorrect claim—the first presents direct laying down; the second preserves the baby’s caused action.
✅ Ta sa jaririn ya kwanta bayan ta ba shi abinci.
She got the baby to lie down after feeding him.
2. Omitting the lower subject–TAM marker after sa.
❌ Ta sa ni karanta takardar.
Incorrect neutral analytic causative—the lower predication is incomplete.
✅ Ta sa ni in sake karanta takardar.
She made me read the document again.
3. Adding da before the embedded subject.
❌ Ruwan sama ya sa da mu mun dawo gida.
Incorrect—da is not an analytic-causative complementizer.
✅ Ruwan sama ya sa mun dawo gida.
The rain made us return home.
4. Coining Grade 5 whenever English uses make.
❌ Dole ne a ƙirƙiri fi’ili mai ar don ‘the news made everyone silent.’
Incorrect—the productive sa construction expresses this cause.
✅ Wannan labarin ya sa mutanen sun yi shiru.
This news made the people fall silent.
5. Dropping da from the Grade 5 long object frame.
❌ Mai gadi ya fitar baƙon daga ofis.
Incorrect in the long Grade 5 construction.
✅ Jami’in tsaro ya fitar da mutumin daga ofishin.
The security officer took the man out of the office.
Key Takeaways
- Grade 5 is one lexical predicate; analytic sa introduces a second predication.
- Grade 5 often packages direct or conventional causation, while sa readily expresses mediated and circumstantial causes.
- The analytic construction is productive; Grade 5 membership and meaning must be verified lexically.
- The caused participant controls the lower subject marking after sa: the subjunctive is the neutral pattern, while discourse can license a realized perfective or maintained imperfective lower situation.
- Grade 5’s da object frame and analytic sa are different systems and may even occur inside one sentence.
