Choose the completive when you present a situation from outside as a bounded whole, a transition reached, or an established state. Choose the continuative when you present it from inside as unfolding, still open, temporarily holding, or recurring. English past versus present is not the decision: Hausa aspect and the verb’s event structure are.
All unlabelled forms are (neutral Nigerian Standard Hausa). Ordinary boko preserves ɓ, ɗ, ƙ and apostrophes but does not mark tone or vowel length. This page supplies a decision procedure; the complete person paradigms belong on the linked concept pages.
The usable diagnostic
Ask these questions in order:
- Does the clause assert that an endpoint or change was reached? Choose the completive.
- Does it locate the listener inside an event or state that remains open at the reference time? Choose the continuative.
- Is it a routine? The continuative can express it when context or a frequency phrase supplies recurrence; -kan may explicitly characterize a habit.
- Is the predicate lexically state-like? Learn its usual Hausa frame. Some established states favor the completive (na sani “I know”), while others favor the continuative (ina so “I want/like,” ina buƙata “I need”).
- Is something fronted or questioned? Keep the aspect decision but use the corresponding relative form where syntax requires it.
Amina ta rubuta sabon rahoton.
Amina wrote / has written the new report. (bounded whole; completion asserted)
Amina tana rubuta sabon rahoton.
Amina is writing the new report. (inside an open event)
This is the core minimal pair. The lexical material stays constant while ta versus tana asks the listener to view the writing differently.
Bounded result versus unfolding process
Verbs with natural endpoints make the contrast especially clear. Opening, fixing, arriving, and finishing culminate in a change or result.
Musa ya gyara tsohon famfon da safe.
Musa repaired the old tap in the morning. (repair treated as complete)
Musa yana gyaran tsohon famfon yanzu.
Musa is repairing the old tap now. (repair in progress)
Baƙin sun isa tashar.
The visitors have arrived at the station. (arrival boundary reached)
Baƙin suna zuwa tashar.
The visitors are coming to the station. (journey still open or recurring)
Hauwa ta buɗe shagon.
Hauwa opened / has opened the shop. (opening event completed)
Hauwa tana buɗe shagon.
Hauwa is opening the shop / regularly opens the shop. (ongoing or habitual from context)
The continuative does not guarantee that the endpoint will ever be reached. Yana gyaran famfo reports an open repair; it does not entail success. The completive ya gyara famfo normally presents the repair as accomplished, though a later event can undo its result.
Musa ya gyara famfon, amma ya sake lalacewa da yamma.
Musa repaired the tap, but it broke again in the evening.
Completion therefore asserts a bounded repair, not an everlasting state.
Activities can be bounded by context
Some verbs do not contain a natural endpoint. Working, talking, and dancing can continue indefinitely. A completive can still package a particular stretch as a finished occasion; a continuative opens a view inside it.
Jiya mun yi aiki har ƙarfe bakwai.
Yesterday we worked until seven. (finished stretch bounded by time)
Jiya da ƙarfe biyar muna aiki a ofis.
Yesterday at five we were working in the office. (inside the same kind of activity)
Baƙin sun yi rawa har tsawon awa biyu.
The guests danced for a full two hours. (the occasion viewed as complete)
Da muka shiga, baƙin suna rawa.
When we entered, the guests were dancing. (ongoing background)
Both pairs can refer to past time. The difference is not tense: jiya and the surrounding narrative establish time, while aspect chooses the viewpoint.
The same logic works in future frames:
Gobe da wannan lokaci muna tsallaka gadar Makurdi.
At this time tomorrow we will be crossing the Makurdi bridge. (open at a future checkpoint)
Zuwa gobe da yamma, mun tsallaka kogin.
By tomorrow evening, we will have crossed the river. (complete by a future checkpoint)
This future-checkpoint completive is context-sensitive and more advanced than ordinary za mu tsallaka “we will cross.” It proves that the completive is not simply a past tense.
Objects can help create a boundary
A quantified or definite object can supply a natural endpoint. Compare drinking as an activity with drinking a delimited quantity.
Yaron yana shan ruwa a yanzu.
The boy is drinking water now. (open activity)
Yaron ya sha kofuna biyu na ruwa.
The boy drank two cups of water. (bounded quantity consumed)
Aisha tana karanta littafin tarihin Kano.
Aisha is reading the Kano history book. (progress through a bounded object, endpoint not asserted)
Aisha ta karanta littafin duka.
Aisha read the whole book. (completion made explicit)
The noun phrase does not mechanically choose aspect. A bounded object makes an endpoint available, but the speaker may still look inside the event with the continuative. Conversely, a duration or narrative frame can bound an atelic activity under the completive.
Continuative does more than “happening now”
The continuative also covers temporary projects, locations, open states, and routines.
Ina karanta wani littafi game da noma a wannan watan.
I am reading a book about farming this month. (active project, not necessarily this second)
Zainab tana zaune a Kaduna yanzu.
Zainab lives/is staying in Kaduna now. (current location or residence)
Musa yana zuwa babbar kasuwa kowace Asabar.
Musa goes to the main market every Saturday. (routine expressed by continuative plus frequency)
English simple present in the last two examples does not require a completive. Yanzu and kowace Asabar help select temporary-state and recurring readings of the open viewpoint.
If recurrence itself is the characterization, -kan can be more explicit:
Musa yakan je kasuwa da sassafe.
Musa usually goes to the market very early. (explicit habitual)
See Continuative versus Habitual rather than forcing every English simple present into one Hausa paradigm.
State predicates must be learned in Hausa frames
The aspect contrast is partly lexical. Established knowledge commonly uses a completive form, while liking, wanting, and needing commonly use continuative frames.
Na san inda aka ajiye makullin.
I know where the key was put. (established state with completive form)
Bayan bayaninsa, na gane matsalar.
After his explanation, I understood the problem. (transition into understanding)
Ina son wannan sabon tsarin saboda yana da sauƙin amfani.
I like this new system because it is easy to use. (state with continuative form)
Muna buƙatar ƙarin kujeru kafin taron.
We need more chairs before the meeting. (state with continuative form)
There is no honest rule that derives all these choices from English. Memorize frequent pairings—na sani, na gane, ina so, ina buƙata—then generalize within Hausa, not from an English list of “stative verbs.”
Information structure changes the form, not the viewpoint
The plain/relative distinction is separate from completive/continuative. Fronted questions and focus select relative forms while preserving the viewpoint.
Me suka gyara jiya?
What did they repair yesterday? (relative completive; bounded repair asked about)
Wace na’ura suke gyarawa yanzu?
Which device are they repairing now? (relative continuative; ongoing repair asked about)
Famfon ne suka gyara jiya.
It was the tap that they repaired yesterday. (focused object, relative completive)
Famfon ne suke gyarawa yanzu.
It is the tap that they are repairing now. (focused object, relative continuative)
The diagnostic substitutions are sun → suka and suna → suke in these environments. Do not choose the relative series because the event is past or because ne is “a tense”; syntax triggers it.
A mini-dialogue where aspect changes the implication
—Amina tana rubuta rahoton? —I, tana rubuta shi, amma ba ta gama ba tukuna. —To, yaushe za ta gama?
—Is Amina writing the report? —Yes, she is writing it, but she has not finished yet. —Then when will she finish?
—Amina ta rubuta rahoton? —I, ta rubuta shi; yana kan teburin manaja. —Madalla, za mu aika shi yau.
—Has Amina written the report? —Yes, she has written it; it is on the manager’s desk. —Excellent, we will send it today.
In the first exchange, the work remains open. In the second, completion licenses the next step. Swapping tana rubuta and ta rubuta would change the practical implication, even though English might use a form of write in both conversations.
Common Mistakes
1. Choosing by English past versus present
❌ Jiya da ƙarfe biyu mun jira likitar.
Wrong for the intended inside view ‘we were waiting at two’; the completive presents the wait as a bounded whole.
✅ Jiya da ƙarfe biyu muna jiran likitar.
Yesterday at two we were waiting for the doctor.
2. Using the continuative while asserting completion
❌ Tana rubuta rahoton, don haka an riga an aika shi.
Contradictory without special context: the report is presented as still being written but also already sent.
✅ Ta rubuta rahoton, don haka an riga an aika shi.
She wrote the report, so it has already been sent.
3. Assuming continuative always means this exact moment
❌ Idan na ce ina karanta wannan littafin a wannan watan, to ina riƙe da shi a hannuna a wannan daƙiƙar.
Incorrect inference—the reading project can remain open across the month without occurring at this exact second.
✅ Ina karanta wannan littafin a wannan watan, amma yanzu ina wurin aiki.
I am reading this book this month, but right now I am at work.
4. Forcing English stative-verb rules onto Hausa
❌ Na so wannan tsarin yanzu.
Not the neutral frame for the intended current state ‘I like this system now.’
✅ Ina son wannan tsarin yanzu.
I like this system now.
5. Confusing viewpoint with focus syntax
❌ Me suna gyarawa yanzu?
Incorrect fronted object question—plain suna must change to relative suke.
✅ Me suke gyarawa yanzu?
What are they repairing now?
Key Takeaways
- The completive presents a bounded whole, reached transition, or established state; the continuative presents an open, ongoing, temporary, or recurring situation.
- Past versus present is not the choice: both aspects can occur in past, present, or future reference frames.
- Lexical endpoints, quantified objects, duration phrases, and discourse checkpoints shape boundedness.
- The continuative can describe routines, while -kan explicitly characterizes habitual recurrence.
- Frequent state predicates must be learned in Hausa frames such as na sani, ina so, and ina buƙata.
- Plain versus relative TAM is an independent syntax decision: preserve aspect while changing sun/suna to suka/suke where focus or questions require it.
