With an active verb, the Hausa plain completive presents an event as a whole: someone entered, cooked, wrote, worked, or changed state. English very often uses a simple past or present perfect, but “past tense” is only a translation shortcut. Hausa places person and completive viewpoint in the preverbal marker and lets context locate that completed event in time.
All unlabelled examples are (neutral Nigerian Standard Hausa). “Active” here covers actions, activities, movements, and changes, not only deliberate acts. Ordinary boko leaves tone and vowel length unmarked.
The marker carries person and completive viewpoint
The lexical verb does not change to agree with the subject. Compare the full paradigm with shiga “enter”:
| Person | Plain-completive marker | Complete expression |
|---|---|---|
| 1st singular | na | na shiga |
| 2nd masculine singular | ka | ka shiga |
| 2nd feminine singular | kin | kin shiga |
| 3rd masculine singular | ya | ya shiga |
| 3rd feminine singular | ta | ta shiga |
| 1st plural | mun | mun shiga |
| 2nd plural | kun | kun shiga |
| 3rd plural | sun | sun shiga |
| impersonal | an | an shiga |
Na shiga ofishin bayan an kira ni.
I entered the office after I was called.
Kin shiga ɗakin da bai dace ba.
You entered the wrong room. (to one female)
Sun shiga mota suka tafi.
They got into the car and left.
The verb shiga remains the same while na, kin, sun identify the subject. The third example begins with a neutral plain form sun; the narrative then uses suka in a linked sequence. Later pages treat narrative distribution in detail.
Bounded events naturally fit the completive
Some active predicates have an inherent endpoint: arriving ends a journey, opening changes a closed door, and finishing reaches a task boundary. The completive packages that endpoint together with the event.
Aisha ta isa Kano da yamma.
Aisha arrived in Kano in the evening.
Musa ya buɗe akwatin ya ɗauko takardun.
Musa opened the box and took out the documents.
Mun kammala gyaran ɗakin.
We completed the room renovation.
These clauses do not say merely that the action was under way. Compare continuative Aisha tana zuwa Kano “Aisha is going to Kano” and Musa yana buɗe akwatin “Musa is opening the box.” The continuative looks inside an unfolding situation; the completive looks at the whole event.
Activities can also be presented as complete
An activity such as working, talking, or dancing has no unavoidable endpoint in its lexical meaning. A completive marker can still bound a particular occasion: the activity happened and is viewed as a finished stretch.
Jiya mun yi aiki har dare.
Yesterday we worked until night.
Baƙin sun yi rawa na awa biyu.
The guests danced for two hours.
Mun tattauna matsalar a taron safe.
We discussed the problem at the morning meeting.
The phrase har dare, the duration na awa biyu, or the event frame a taron safe supplies a boundary. This is why “completive” does not mean every verb must name a naturally completed task. It describes how the speaker presents the occurrence.
Result and current relevance favor present-perfect English
When a completed action produces a result relevant now, English often chooses the present perfect. Hausa does not need a different personal paradigm.
Na rasa makullin gidan; ba zan iya buɗe ƙofar ba.
I have lost the house key; I will not be able to open the door.
Hauwa ta dafa abinci, don haka mu ci yanzu.
Hauwa has cooked the food, so let us eat now.
Yara sun karya gilashin; ga shi nan a ƙasa.
The children have broken the glass; there it is on the floor.
Nothing in na, ta, sun specifically means English have. The visible present result motivates the English translation. A finished-time phrase instead favors the simple past:
Hauwa ta dafa abincin jiya da yamma.
Hauwa cooked the food yesterday evening.
Time adverbs anchor the same aspectual form
The plain completive can be complete relative to a past, present, or future checkpoint.
Zuwa ƙarfe goma jiya, mun bar garin.
By ten o'clock yesterday, we had left the town.
Yanzu mun gyara matsalar.
Now we have fixed the problem.
Zuwa ƙarfe goma gobe, mun bar garin.
By ten o'clock tomorrow, we will have left the town.
The English auxiliary changes from had to have to will have. Hausa retains mun bar because in each clause departure is complete by the reference point. See relative time and time adverbs.
An ordinary za future takes a different perspective:
Za mu bar garin da ƙarfe goma gobe.
We will leave the town at ten tomorrow.
Here departure is scheduled after the present reference point, not presented as already complete by a checkpoint.
An overt subject still requires the marker
English speakers may expect a noun subject to stand directly before a tense-bearing verb. Hausa instead places an agreeing subject–TAM marker between the noun and the lexical predicate.
Direban ya tsayar da motar a bakin hanya.
The driver stopped the car by the roadside.
Matan sun wanke kayan da safe.
The women washed the clothes in the morning.
Ɗaliban sun rubuta jarabawar a babban ɗaki.
The students wrote the examination in the main hall.
In each clause the noun identifies the participant, while ya or sun makes the verbal predicate finite and supplies completive aspect. Neither element is redundant.
Plain, relative, and negative frames
Neutral reports use the plain completive. Constituent focus and relative clauses select the relative completive; polarity selects a separate negative frame.
Kun sayi shinkafa a kasuwa.
You all bought rice at the market. (plain completive)
Me kuka saya a kasuwa?
What did you all buy at the market? (relative completive)
Ba ku sayi shinkafa ba.
You all did not buy rice. (negative completive)
Relative kuka is not a special past form; question syntax selects it. Negative ba ku … ba does not retain affirmative kun. The same active predicate saya receives three clause frames.
Littafin da muka karanta ya yi amfani sosai.
The book that we read was very useful. (relative clause)
The relative clause uses muka, while the main clause uses plain masculine singular ya with state-like yi amfani.
Active does not always mean intentional
Changes and events can be dynamic even when no one plans them. Their completive still presents the transition as a whole.
Itacen ya faɗi saboda iska.
The tree fell because of the wind.
Fitilar ta mutu lokacin da wutar ta ɗauke.
The lamp went out when the electricity failed.
This matters because grammatical “active” here is about event structure, not moral agency or the active voice of an English grammar exercise.
Practice: choose an event viewpoint
Compare the same active predicate under completive and continuative viewpoints.
Yaran sun tsallaka titi.
The children crossed the road. (event viewed as a whole)
Yaran suna tsallaka titi.
The children are crossing the road. (event unfolding)
Amina ta rubuta rahoton.
Amina wrote / has written the report. (bounded event)
Amina tana rubuta rahoton.
Amina is writing the report. (activity in progress)
The lexical verb alone does not supply the contrast. The preverbal complex tells the listener which viewpoint to adopt.
Common Mistakes
1. Treating every completive as an English simple past.
❌ Na rasa katina.
Incomplete analysis if forced to mean only ‘I lost my card’; a present result may make English ‘I have lost my card’ natural.
✅ Na rasa katina; ba ya tare da ni yanzu.
I have lost my card; I do not have it with me now.
2. Dropping the marker after a noun subject.
❌ Matan wanke kayan.
Incorrect — the plural subject requires sun.
✅ Matan sun wanke kayan.
The women washed the clothes.
3. Changing only the lexical verb to express aspect.
❌ Ni rubuta wasiƙar jiya.
Incorrect — independent ni plus a bare lexical verb is not a finite completive clause.
✅ Na rubuta wasiƙar jiya.
I wrote the letter yesterday.
4. Using a relative form in a neutral assertion.
❌ Muka sayi abinci da safe.
Incorrect as the intended context-free neutral report.
✅ Mun sayi abinci da safe.
We bought food in the morning.
5. Forcing za into a by-deadline reading.
❌ Zuwa gobe, za mu kammala aikin.
Not the intended viewpoint if the job is to count as already complete by tomorrow.
✅ Zuwa gobe, mun kammala aikin.
By tomorrow, we will have completed the work.
Key Takeaways
- With active predicates, the completive presents an action, activity, movement, or change as a bounded whole.
- Na, ka, kin, ya, ta, mun, kun, sun, an carry person and completive viewpoint before the verb.
- English simple past, present perfect, past perfect, and future perfect can all translate the Hausa completive in different contexts.
- An overt noun subject still needs its agreeing subject–TAM marker.
- Plain versus relative marking depends on clause structure, while negative clauses use their own subject forms.
