Contrastive correction does more than report an event: it rejects one proposed value and replaces it with another. If somebody says that Musa repaired the generator, Ba Musa ba ne ya gyara janareton; Bello ne means “It was not Musa who repaired the generator; it was Bello.” The repair remains background; the identity of the repairer is what changes.
This page builds on the agreement and TAM frame introduced in Focus with ne and ce.
All unlabelled examples are (neutral Nigerian Standard Hausa). Ordinary boko spells ɓ, ɗ, ƙ, ’y but does not mark tone or vowel length. Intonation can make a correction sound insistent, but the reliable grammar comes from the corrective frame, focus position, ne/ce, and—where the aspect distinguishes it—relative TAM.
What a correction preserves and what it replaces
Begin with a neutral statement:
Ma’aikatan sun gyara janareton jiya.
The workers repaired the generator yesterday. (neutral report)
A speaker can question its subject or object:
Su wa suka gyara janareton jiya?
Who repaired the generator yesterday?
Me ma’aikatan suka gyara jiya?
What did the workers repair yesterday?
Both fronted questions use relative suka, not plain sun. A focused answer identifies a value against the background proposition:
Ma’aikatan ne suka gyara janareton jiya.
The workers are the ones who repaired the generator yesterday.
A correction explicitly rejects a rival value:
Ba injin famfo ba ne ma’aikatan suka gyara; janareton ne suka gyara.
It was not the pump engine that the workers repaired; they repaired the generator.
The structure is roughly:
ba + REJECTED FOCUS + ba + ne/ce + BACKGROUND; CORRECT FOCUS + ne/ce (+ BACKGROUND)
The second background clause may be omitted when it is completely recoverable, as in janareton ne. This omission is ordinary conversational economy; ne itself has not become a tense-bearing verb.
Correcting the subject
Subject correction keeps the event and replaces the actor. The rejected noun phrase takes its own appropriate ne/ce, and the accepted alternative does the same.
Ba Musa ba ne ya kawo kayan; Amina ce ta kawo su da safe.
It was not Musa who brought the goods; Amina brought them in the morning.
Ba Zainab ba ce ta kira mai gyaran; Hauwa ce ta kira shi.
It was not Zainab who called the repairer; Hauwa called him.
Ba direbobin ba ne suka makara; fasinjojin ne suka makara.
It was not the drivers who were late; it was the passengers.
Masculine singular Musa takes ne, feminine singular Zainab/Amina/Hauwa takes ce, and plurals take ne. The following subject–TAM form still agrees with the actor: ya, ta, or suka. These are two distinct agreement decisions.
In the completive plural, correction makes the relative paradigm visible: neutral direbobin sun makara contrasts with focused direbobin ne suka makara. Singular ordinary spelling hides the plain/relative contrast in ya and ta, but the focus construction still selects the relative member.
Correcting the object
Object correction fronts the object and leaves its ordinary postverbal position empty. The focus particle agrees with that object; the relative TAM marker agrees with the clause’s subject.
Ba jakar ba ce muka saya; akwatin ne muka saya.
It was not the bag that we bought; we bought the box.
Ba tsohon famfon ba ne suke gyarawa; sabon famfon ne suke gyarawa.
It is not the old tap that they are repairing; they are repairing the new tap.
In the first example, feminine jakar selects ce and masculine akwatin selects ne; first-person plural muka belongs to “we.” In the second, third-person plural suke remains the subject–TAM marker even though focused famfo is singular.
Do not repeat the direct object with shi/ta/su after the verb in this compact focus construction. The fronted object and the postverbal gap form one dependency.
Correcting a place, time, or manner
A whole adverbial or prepositional phrase normally takes stabilizing ne, even if it contains a feminine noun.
Ba a kasuwa ba ne muka haɗu; a banki ne.
It was not at the market that we met; it was at the bank.
Ba jiya ba ne suka aika saƙon; yau da safe ne.
It was not yesterday that they sent the message; it was this morning.
Ba da bas ba ne ta zo; da jirgin ƙasa ne.
She did not come by bus; she came by train.
The prepositions a and da remain with their complements. English can say “the market is not where we met” or strand a preposition in other focus sentences, but canonical Hausa fronts the whole grammatical phrase: a kasuwa, da mota, daga Kano.
Notice that a kasuwa ne has ne, not ce. The focused unit is the entire locative phrase, not the feminine noun kasuwa by itself.
Information seeking is not yet correction
An open content question asks the listener to supply a missing value:
Ina kuka ajiye kwalayen?
Where did you all put the boxes?
A focused polar question proposes a candidate:
A ɗakin baya ne kuka ajiye su?
Was it in the back room that you put them?
A correction rejects that candidate and supplies another:
A’a, ba a ɗakin baya ba ne muka ajiye su; a cikin shago ne.
No, we did not put them in the back room; we put them inside the shop.
The information structure grows more specific across these three moves: open request → proposed answer → rejected and replaced answer. Hausa does not need English do-support, inversion, or one obligatory question-final rise. Standard question punctuation and the morphosyntax make the contrast clear in writing.
Relative TAM is part of the construction
Completive and continuative focus use the same special paradigms found after fronted wh-words and in canonical relative clauses.
| Neutral | Corrective focus |
|---|---|
| Mun sayi rigar. | Ba rigar ba ce muka saya; takalmi ne. |
| Sun kira Musa. | Ba Musa ba ne suka kira; Bello ne. |
| Muna jiran likita. | Ba likitan ba ne muke jira; ma’aikaciyar jinya ce. |
| Suna aiki da safe. | Ba da safe ba ne suke aiki; da dare ne. |
The visible changes mun → muka, sun → suka, muna → muke, and suna → suke are grammatical, not merely emphatic pronunciation. The connection is deep: wh-fronting, relative clauses, and fronted focus all link a prominent phrase to a position interpreted inside the following clause. Hausa marks that dependency in completive and continuative TAM.
With future za, there is no separate relative series:
Ba gobe ba ne za su dawo; jibi ne.
They will not return tomorrow; they will return the day after tomorrow.
Here the correction remains clear from fronting and ne, while za su supplies future time.
Correction versus denial of the whole event
Compare these two answers:
Ba Musa ba ne ya rufe shagon; Amina ce.
It was not Musa who closed the shop; it was Amina. (the closing is accepted)
Musa bai rufe shagon ba; shagon ya kasance a buɗe.
Musa did not close the shop; the shop remained open. (the proposed event is denied)
The first preserves “someone closed the shop.” The second does not replace Musa with another closer; it denies his action and then reports the resulting state. English stress can blur this distinction, but Hausa gives you two different grammatical structures.
A natural dialogue
—Musa ne ya kawo sabuwar na’urar? —A’a, ba Musa ba ne ya kawo ta; Zainab ce. —Jiya ne ta kawo ta? —A’a, ba jiya ba ne; yau da safe ne. —To, sabuwar na’urar ce ma’aikatan suke gwadawa yanzu? —Eh, ita ce suke gwadawa.
—Was Musa the one who brought the new machine? —No, Musa did not bring it; Zainab did. —Did she bring it yesterday? —No, not yesterday; it was this morning. —So, is the new machine what the workers are testing now? —Yes, that is what they are testing.
The speakers successively correct the actor and the time, then confirm the object. Ce agrees with the feminine names and na’urar; temporal yau da safe takes stabilizing ne. Relative suke marks the ongoing object-focus relation in the final exchange.
Common Mistakes
1. Keeping plain TAM after a fronted correction
❌ Ba Musa ba ne sun kira; Bello ne.
Incorrect canonical correction—sun is plain completive.
✅ Ba Musa ba ne suka kira; Bello ne.
It was not Musa whom they called; it was Bello.
2. Choosing the particle from the following subject
❌ Ba rigar ba ne muka saya; takalman ne.
Incorrect—feminine rigar requires ce.
✅ Ba rigar ba ce muka saya; takalman ne.
It was not the dress that we bought; it was the shoes.
3. Relying on English intonation alone
❌ MA’AIKATAN sun gyara janareton.
Incorrect written Hausa for the intended canonical subject correction; capitalization cannot replace the focus frame or relative TAM.
✅ Ma’aikatan ne suka gyara janareton, ba Musa ba.
The workers repaired the generator, not Musa.
4. Repeating a corrected direct object
❌ Janareton ne suka gyara shi, ba famfon ba.
Incorrect as the compact object-gap focus pattern; shi needlessly repeats the focused object.
✅ Janareton ne suka gyara, ba famfon ba.
It was the generator that they repaired, not the tap.
5. Using focus correction to deny the event
❌ Ba Musa ba ne ya zo; babu wanda ya zo.
Semantically mismatched if the first clause is meant to replace Musa with another visitor while the second says nobody came.
✅ Musa bai zo ba; babu wanda ya zo.
Musa did not come; nobody came.
Key Takeaways
- Contrastive correction rejects one value but normally preserves the background event.
- The standard frame is ba + rejected focus + ba + ne/ce, followed by the accepted alternative.
- Focus particles agree with referential noun phrases; whole adverbial and prepositional phrases normally take ne.
- Fronted completive and continuative corrections use relative TAM such as muka/suka and muke/suke.
- Ne/ce identifies the correction; it does not carry tense and it is not an ordinary agreeing verb.
- To deny the event itself, use clause negation rather than inventing a replacement focus.
