Exhaustive focus identifies the complete relevant answer: “Musa and Amina—and nobody else in the current set.” Nonexhaustive focus highlights one true alternative without excluding others: “Musa too, perhaps among others.” Particleless fronting can support the second reading. Overt ne/ce, by contrast, has been analyzed as conventionally exhaustive within the live alternative set, though it is not a word-for-word equivalent of English only. Explicit kaɗai “only/alone” and ma “also/too” state the strongest contrasts directly.
For the particle’s agreement pattern before this semantic contrast is added, see Focus with ne and ce.
All unlabelled examples are (neutral Nigerian Standard Hausa). Ordinary boko omits tone and vowel length. This page uses exhaustive in the linguistic sense “excludes the other contextually relevant alternatives,” not in the everyday sense “detailed or tiring.”
Focus creates alternatives
Start with a neutral report:
Yaran sun kawo kujeru zuwa ɗakin taro.
The children brought chairs to the meeting room. (neutral report)
The subject and object questions open different sets of alternatives:
Su wa suka kawo kujeru zuwa ɗakin taro?
Who brought chairs to the meeting room?
Me yaran suka kawo zuwa ɗakin taro?
What did the children bring to the meeting room?
A focused answer selects a value from the relevant set:
Musa da Amina ne suka kawo kujerun.
Musa and Amina are the ones who brought the chairs.
If the question asks for the complete list of carriers, the overt-ne answer identifies Musa and Amina exhaustively within that candidate set. This does not exclude people outside the live set or people who contributed in a different role: someone else may have arranged the room without belonging to the set of chair carriers.
The strong identificational effect of ne and ce
Fronted FOCUS + ne/ce + relative clause commonly presents the focused value as the answer that fits a presupposed open slot.
Zainab ce ta rubuta rahoton.
Zainab is the one who wrote the report.
Rahoton kuɗi ne muka kammala.
It was the financial report that we completed.
A ofishin manaja ne suke taro.
It is in the manager’s office that they are meeting.
The background propositions—someone wrote the report, we completed a report, they are meeting somewhere—are treated as given or readily accommodated. The focused constituent identifies the missing value. This architecture often produces an exhaustive inference because an identification normally aims to settle the question.
There is an important analytical disagreement. One influential account treats ne/ce as a focus-sensitive exhaustivity marker whose inference is conventional rather than part of the sentence’s truth conditions. Other accounts emphasize deictic identification or copular/stabilizing behavior. All agree that focus itself does not require the particle. For learners, the firm facts are:
- ne/ce makes identification overt;
- it agrees with a focused referential noun phrase but does not carry tense;
- influential analyses assign it an exhaustive identification within the relevant alternative set;
- it is not semantically identical to explicit, truth-conditional kaɗai “only/alone.”
Say kaɗai when “only” must be explicit
Use kaɗai when excluding every other relevant alternative is essential to the message.
Aisha kaɗai ce ta san inda aka ajiye makullin.
Aisha alone knows where the key was put.
Wannan fayil kaɗai ne muka aika wa manajan.
This is the only file we sent to the manager.
A ranar Litinin kaɗai ne ake rufe ofishin.
Monday is the only day on which the office is closed.
Here kaɗai carries explicit truth-conditional exclusion. Ne supports the identificational focus frame, and relative muka/ake builds the background clause. Removing kaɗai removes the overt word meaning “only,” even though influential analyses still assign ne/ce a weaker conventional exhaustive effect.
Compare:
| Hausa | Safest interpretation |
|---|---|
| Musa ne ya kawo makullin. | Musa is the identified key-bringer; influential analyses treat the identification as exhaustive within the live set. |
| Musa kaɗai ne ya kawo makullin. | Musa alone brought the key; other relevant people are explicitly excluded. |
| Musa ma ya kawo makulli. | Musa also brought a key; at least one additional alternative is included. |
Nonexhaustive and additive focus
The additive particle ma explicitly signals that the named alternative is not alone.
Amina ma ta taimaka wajen shirya ɗakin.
Amina also helped prepare the room.
Ma’aikatan dare ma sun ga matsalar.
The night workers saw the problem too.
These clauses keep ordinary word order and, in the plural example, plain completive sun. They are not canonical fronted clefts. Ma adds Amina or the night workers to alternatives already true, so an exhaustive “and nobody else” reading would contradict the additive meaning.
Fronting can also occur without overt ne/ce, and it need not claim exclusivity:
Littattafai muka saya; mun kuma sayi kayan rubutu.
Books are what we bought; we also bought stationery.
Relative muka shows that littattafai is fronted focus, while the second clause expressly adds another purchase. This is why “fronted focus always means only” is too strong. The discourse can highlight books without excluding stationery.
In ordinary conversation, in-situ focus may also leave the focused phrase in its usual position and use plain TAM. Its interpretation relies more on context and prosody, which ordinary boko does not fully represent. For production, use ma for a clearly additive meaning and kaɗai for a clearly exclusive one.
Relative TAM marks the dependency, not exhaustivity
Fronted completive and continuative focus selects the relative paradigms whether the resulting interpretation is strongly exhaustive or merely contrastive.
| Neutral clause | Fronted focus |
|---|---|
| Mun sayi littattafai. | Littattafai ne muka saya. |
| Sun kawo kujeru. | Kujeru ne suka kawo. |
| Muna neman manaja. | Manajan ne muke nema. |
| Suna gyara motar. | Motar ce suke gyarawa. |
The changes mun → muka, sun → suka, muna → muke, and suna → suke indicate the fronted focus relation. They do not mean “only.” Particleless same-predicate focus can be explicitly additive:
Motar suke gyarawa; babur ɗin ma suke gyarawa.
They are repairing the car; they are repairing the motorcycle too.
Relative suke marks each fronted dependency, while the absence of ne/ce permits the additive continuation. Relative TAM therefore diagnoses fronting, not exhaustivity.
English speakers often rely on nuclear stress—“They repaired the CAR”—and expect the listener to infer the intended alternative set. Hausa can also use discourse prosody, but canonical fronting uses overt word order and relative TAM. Stressing an English translation does not license plain sun/suna after a fronted constituent.
Presupposition does not equal exhaustivity
Focus often backgrounds an event proposition. Rahoton ne muka aika normally treats “we sent something” as accepted and identifies the thing as the report. That is a presuppositional effect. Exhaustivity asks a different question: does the sentence exclude our having sent anything else?
Rahoton ne muka aika da safe; hotunan kuma muka aika da yamma.
The report is what we sent in the morning; the photographs, on the other hand, we sent in the evening.
The first focus identifies the morning shipment without excluding a separate afternoon shipment. Backgrounding an event and exhausting an alternative set are therefore not the same operation.
By contrast, explicit kaɗai closes the relevant set:
Rahoton kaɗai ne muka aika da safe; ba mu aika hotunan ba.
The report was the only thing we sent in the morning; we did not send the photographs.
Information seeking, selection, and correction
An open question requests a value:
Wa yake karɓar baƙi yau?
Who is receiving the visitors today?
A selective question offers alternatives:
Musa ne yake kula da shagon, ko Bello?
Is Musa looking after the shop, or Bello?
A correction rejects one candidate:
Ba Musa ba ne yake kula da shagon; Bello ne.
It is not Musa who is looking after the shop; it is Bello.
The selective context and correction identify Bello exhaustively within the two-person candidate set for caretaker. Bello ne may still leave room for people outside that candidate set or for people present in a different role, but not for another equally relevant caretaker inside the same live set.
A natural dialogue
—Su wa suka kammala rahoton? —Amina da Bashir ne suka kammala shi. —Su kaɗai ne suka yi aikin? —A’a, Musa ma ya duba alƙaluman, amma Amina da Bashir kaɗai ne suka rubuta rahoton ƙarshe. —To, ba Amina kaɗai ba ce ta rubuta shi? —A’a, ita da Bashir ne.
—Who completed the report? —Amina and Bashir completed it. —Were they the only ones who did the work? —No, Musa also checked the figures, but only Amina and Bashir wrote the final report. —So Amina did not write it alone? —No, it was her and Bashir.
The first answer is naturally complete for “who completed it.” The follow-up separates the larger project from final authorship. Ma adds Musa nonexhaustively; kaɗai explicitly closes the author set.
Common Mistakes
1. Translating every ne or ce as “only”
⚠️ Amina ce ta kira.
Grammatical: Amina is the one who called. The mistake is translating ce mechanically as truth-conditional English ‘only,’ even though an influential analysis assigns it a conventional exhaustive effect.
✅ Amina kaɗai ce ta kira.
Only Amina called.
2. Using kaɗai for an additive meaning
❌ Musa kaɗai ne ya taimaka, Amina ma ta taimaka.
Contradictory in one unchanged context—Musa alone helped, but Amina also helped.
✅ Musa ya taimaka, Amina ma ta taimaka.
Musa helped, and Amina helped too.
3. Keeping plain TAM after fronted focus
❌ Littattafai ne mun saya.
Incorrect canonical fronted focus—mun is plain completive.
✅ Littattafai ne muka saya.
It was books that we bought.
4. Treating ne or ce as an agreeing verb
❌ Amina ce rubuta rahoton.
Incorrect—ce supplies neither subject agreement nor completive aspect.
✅ Amina ce ta rubuta rahoton.
Amina is the one who wrote the report.
5. Assuming intonation alone expresses the written contrast
❌ MUSA sun kawo kujerun.
Incorrect written form for canonical fronted subject focus; capitalization cannot replace Hausa relative TAM.
✅ Musa ne ya kawo kujerun; Bello kuma ya kawo teburan.
Musa brought the chairs; Bello, on the other hand, brought the tables.
Key Takeaways
- Exhaustive focus excludes other contextually relevant alternatives; nonexhaustive focus leaves room for more.
- Overt ne/ce is optional for focus, but influential analyses assign it an exhaustive identification within the relevant alternative set; kaɗai expresses explicit “only/alone,” while particleless focus can remain nonexhaustive.
- Use kaɗai when exclusion must be explicit and ma when inclusion of another alternative must be explicit.
- Relative muka/suka/muke/suke diagnoses fronted focus; it does not encode exhaustivity by itself.
- Presupposing an event and exhaustively identifying one value are related but separate discourse effects.
- Always state the relevant comparison set: exhaustivity is never an unrestricted claim about everything in the world.
