Hausa distinguishes an open condition from a counterfactual one by construction, not by copying English past and would. The core unreal frame places da before both the condition (protasis) and its consequence (apodosis): da P, da Q. TAM inside each clause then helps locate the imagined alternative in the past, present, or future.
The open-condition use of the potential result is treated separately in Indefinite Future after Conditional Setups.
All unlabelled forms are (neutral Nigerian Standard Hausa). Ordinary boko has no tone or vowel-length marks. Because completive, subjunctive, and indefinite-future forms can look alike in writing, clause position and the surrounding construction are sometimes essential to interpretation.
Open idan/in versus counterfactual da … da …
An idan/in clause can state an open premise whose realization remains possible. Paired da … da … presents an alternative separated from the actual or expected world.
Idan motar ta gyaru yau, za mu tafi Kano gobe.
If the car is repaired today, we will go to Kano tomorrow. (open condition)
Da motar ta gyaru jiya, da mun tafi Kano.
If the car had been repaired yesterday, we would have gone to Kano. (past counterfactual)
The first speaker leaves tomorrow’s trip conditional on a still-open repair. The second looks back at an unrealized repair and imagines its unrealized result. Da is repeated because both propositions belong to that alternative world.
The neutral past-counterfactual paradigm
Past counterfactual clauses commonly use the general completive, not the narrative/relative completive merely because the imagined event is past. The table gives affirmative and negative protases with zo “come.”
| Person | Affirmative protasis | Negative protasis |
|---|---|---|
| 1st singular | da na zo | da ban zo ba |
| 2nd masculine singular | da ka zo | da ba ka zo ba |
| 2nd feminine singular | da kin zo | da ba ki zo ba |
| 3rd masculine singular | da ya zo | da bai zo ba |
| 3rd feminine singular | da ta zo | da ba ta zo ba |
| 1st plural | da mun zo | da ba mu zo ba |
| 2nd plural | da kun zo | da ba ku zo ba |
| 3rd plural | da sun zo | da ba su zo ba |
| impersonal | da an zo | da ba a zo ba |
The consequence can likewise contain a general completive when it describes the unreal past result.
Da sun taimake mu, da mun gama aikin jiya.
If they had helped us, we would have finished the work yesterday.
Da na san za a rufe hanya, da na bi wata hanya.
If I had known that the road would be closed, I would have taken another route.
Da an sanar da mu da wuri, da mun halarci taron.
If we had been informed early, we would have attended the meeting.
The lexical verbs do not carry special counterfactual endings. General completive sun/mun/an/na appears after the framing da.
Past time comes from the whole frame
The paired da frame marks unreality; it does not by itself mean “past.” Past adverbs, completive viewpoint, and knowledge of what actually happened combine to produce a past counterfactual.
Da jirgin bai yi jinkiri jiya ba, da mun isa kafin fara taron.
If the flight had not been delayed yesterday, we would have arrived before the meeting began.
Da ruwa ya ƙaru sosai, da ba mu iya tsallaka kogin ba.
If the water had risen greatly, we would not have been able to cross the river.
The negative protasis bai yi … ba and negative consequence ba mu iya … ba each close their own scope with ba. The second example imagines a rise that did not occur and a resulting inability that therefore did not become actual.
Negation can reverse which proposition is known to be false:
Da ban manta da maɓallin ba, da na buɗe ofishin da wuri.
If I had not forgotten the key, I would have opened the office early.
Here the counterfactual implicates that the speaker did forget the key and did not open early.
Present counterfactuals use an appropriate state frame
A present contrary-to-fact condition often uses a continuative or nonverbal predicate in the first clause and a future, potential, or completive-shaped result in the second.
Da muna da isasshen kuɗi yanzu, da za mu sayi sabon injin.
If we had enough money now, we would buy a new engine.
Da Aisha tana nan, da ta taimake mu.
If Aisha were here, she would help us.
Muna da expresses present possession, while Aisha tana nan locates Aisha. The overt feminine noun retains tana. The result da za mu sayi makes the projected purchase explicit; da ta taimake mu receives a counterfactual result reading from the paired frame.
English uses past-looking had/were for present unreality. Hausa need not imitate that “fake past.” It selects a predicate appropriate to the imagined present state and lets da … da … mark the alternative world.
Remote future hypotheses commonly retain za
A hypothetical future that the speaker treats as remote can use za in the protasis. The result may also use za.
Da za ka zo gobe, da za mu tanadar maka ɗaki.
If you were to come tomorrow, we would prepare a room for you. (to one male)
Da za a yi ruwa gobe, da za mu mayar da wasan cikin zaure.
If it were to rain tomorrow, we would move the event indoors.
This contrasts with open Idan za ka zo gobe, ka sanar da ni yau “If you are going to come tomorrow, tell me today.” The za form itself does not mean counterfactual; repeated da supplies the remote/unreal framing.
Hausa can also use a completive-shaped protasis for a hypothetical future in some contexts, especially where the imagined event is taken as a bounded trigger. Using za is the clearest production choice when the future orientation itself matters.
Several TAM choices are possible in the result
The apodosis is not an English would slot with one obligatory Hausa equivalent. Depending on temporal perspective and stance, it can contain a general completive, za future, an indefinite/potential future, or sai plus a subjunctive result.
Da mun tashi da wuri, da ma isa kafin azahar.
If we had left early, we would probably have arrived before noon. (potential result)
Da sun amince da shirin, da za mu fara aikin yanzu.
If they had approved the plan, we would be starting the work now. (za result)
Da ya zo da wuri, da sai mu tafi tare.
If he came early, then we would go together. (sai plus subjunctive result)
Potential ma has a long falling vowel in speech, though ordinary ma does not show it. It shades the result as a likely consequence under the imagined condition. Za mu gives explicit prospective framing. Sai mu presents the consequence as what would then follow. These alternatives are discourse choices, not free word-for-word replacements in every clause.
Plain versus relative completive inside the frame
Neutral past counterfactuals use general mun/kun/sun/an. Relative forms appear when their independent syntactic or information-structural licensing is present, such as constituent focus.
Da guba suka ba ta, da ta haɗiye.
If it had been poison that they gave her, she would have swallowed it. (focus on guba)
The fronted focused object guba licenses suka. Without such focus, a neutral “if they had given her…” begins da sun ba ta …, not da suka ba ta merely because the scenario is past. Narrative foregrounding and counterfactual framing are separate systems.
Similarly, a relative clause embedded in a counterfactual retains its relative form:
Da sun karanta rahoton da muka aika, da sun fahimci matsalar.
If they had read the report that we sent, they would have understood the problem.
Muka aika is licensed inside rahoton da …; the matrix counterfactual clauses use general sun.
Active and stative predicates locate alternatives differently
Completed active events readily form past counterfactuals: help, depart, arrive, or open did not occur. States commonly form present alternatives: possessing money, being present, knowing an answer.
Da Musa ya san amsar, da bai yi shiru ba.
If Musa knew the answer, he would not remain silent.
Stative ya san has a present-state interpretation inside the counterfactual despite completive morphology. The negative result bai yi shiru ba is understood counterfactually through the paired frame. This is another reason not to label ya simply “past.”
Regret with da ma
The expanded opener da ma can introduce a regretful “if only” wish (emphatic conversational/literary). It often stands without a fully expressed consequence because the unwanted reality is obvious.
Da ma ban sayar da gonar ba!
If only I had not sold the farm!
Da ma mun saurari shawararta tun farko!
If only we had listened to her advice from the beginning!
This is not potential ma after a subject. It is the fixed regretful sequence da ma before a clause.
Exercises
Build the paired frame. (1) Past affirmative: “If they had called us, we would have come” → Da sun kira mu, da mun zo. (2) Negative condition: “If she had not forgotten, she would have brought it” → Da ba ta manta ba, da ta kawo shi. (3) Present state: “If we had time, we would help you all” → Da muna da lokaci, da za mu taimake ku. (4) Remote future: “If it were to rain tomorrow, we would stay home” → Da za a yi ruwa gobe, da za mu zauna gida. (5) Focus the object: neutral Da sun ba ta magani… becomes Da magani suka ba ta… when “medicine” is contrastively focused.
Common Mistakes
1. Using an open condition for a known unreal past
❌ Idan motar ta gyaru jiya, mun tafi Kano.
Incorrect for the intended known counterfactual; this lacks the paired unreal frame.
✅ Da motar ta gyaru kafin dare, da mun kama hanya da sassafe.
If the car had been repaired before nightfall, we would have set off very early.
2. Omitting da before the consequence
❌ Da sun taimake mu, mun gama aikin.
Incorrect as a balanced counterfactual frame; the result is presented as an actual assertion.
✅ Da sun taimake mu, da mun gama aikin.
If they had helped us, we would have finished the work.
3. Copying English fake past into a present state
❌ Present counterfactuals always require a Hausa past-tense verb.
Incorrect — Hausa uses da framing plus the TAM appropriate to the imagined state.
✅ Da Aisha tana nan yanzu, da za ta taimake mu.
If Aisha were here now, she would help us.
4. Leaving negative scope unclosed
❌ Da jirgin bai yi jinkiri, da mun iso.
Incorrect — negative completive bai requires final ba.
✅ Da jirgin bai yi jinkiri ba, da mun iso da wuri.
If the flight had not been delayed, we would have arrived early.
5. Replacing general sun with narrative suka
❌ Da suka taimake mu, da muka gama.
Incorrect as the intended neutral counterfactual solely on the assumption that suka/muka mean past.
✅ Da sun taimake mu, da mun gama.
If they had helped us, we would have finished.
Key Takeaways
- The core counterfactual frame is da P, da Q; open idan/in conditions are not automatically counterfactual.
- Past counterfactuals commonly use the general completive in both clauses, including mun/kun/sun/an.
- Present alternatives can use continuative or nonverbal states; remote future protases often retain za.
- The consequence can use a completive, za, the indefinite future, or sai + subjunctive, depending on meaning.
- Negative clauses keep their full polarity frames, including closing ba where required.
- Relative completive forms need independent focus or relative-clause licensing; they are not default counterfactual past markers.
