A restrictive relative helps identify which person or thing is meant: ɗaliban da suka ci jarabawa “the students who passed the examination.” A nonrestrictive, or appositive, relative assumes that its antecedent is already identifiable and adds a parenthetical comment: Hauwa, wadda ta ci jarabawa, ... “Hauwa, who passed the examination, ...”. Hausa expresses this difference through the whole noun phrase, prosody, TAM, and discourse status—not through commas or one relative marker alone. Restrictives can use compact linked head + da or a bare/indefinite head followed by agreeing wanda/wadda/waɗanda; nonrestrictives normally use the agreeing form.
All unlabelled examples are (neutral Nigerian Standard Hausa). Ordinary boko uses ɓ, ɗ, ƙ, ’y but does not mark tone or vowel length.
The component parts of the compact pattern are introduced in the relative clauses with da overview.
Restrictive relatives narrow the reference
The canonical compact restrictive construction has linked head + da + relative clause. The clause contributes information needed to select the intended member or subset.
Mutumin da ya kawo fam ɗin yana jiran amsa.
The man who brought the form is waiting for an answer.
Macen da take kula da shagon ta tafi banki.
The woman who looks after the shop has gone to the bank.
Ma’aikatan da suka kammala horon za su fara aiki ranar Litinin.
The employees who completed the training will start work on Monday.
The linked heads mutumin, macen, ma’aikatan mark masculine singular, feminine singular, and plural noun phrases. The following da never changes form. The relative TAM agrees with the understood subject: ya, take, suka.
Restrictive object relatives follow the same noun-phrase pattern, but their overt internal subject controls TAM:
Na ajiye takardun da lauya ya aiko mana.
I filed the documents that the lawyer sent us.
Masculine lauya controls ya; plural takardun is the direct-object gap after aiko. The clause identifies which documents were filed.
A second restrictive frame uses an agreeing relative form
Restrictive meaning is not limited to invariant da. With a bare or indefinite head, an agreeing complex relative form can introduce the selecting clause:
Wani mutum wanda ya zo daga Katsina yana jiranka a waje.
A man who came from Katsina is waiting for you outside. (addressing one male)
Wata mace wadda take aikin jinya ta taimaka mana.
A woman who works as a nurse helped us.
Compare compact mutumin da ya zo / macen da ta zo with wani mutum wanda ya zo / wata mace wadda ta zo. In the second frame, the lexical head is not given the joined restrictive linker before wanda/wadda. The agreeing form can therefore introduce a headed restrictive relative, stand headlessly, or introduce a nonrestrictive relative; form alone does not settle the interpretation.
Many speakers distinguish restrictive and nonrestrictive agreeing forms through tone and prosody. Ordinary boko does not display tone, so discourse status, phrasing, TAM, and the referent’s identifiability remain essential evidence.
Nonrestrictive relatives continue an established discourse referent
A proper name, demonstratively identified noun phrase, or contextually unique role may already be enough to identify its referent. An appositive relative then adds a side comment. Agreeing wanda, wadda, waɗanda is especially clear in careful speech and writing.
Bello, wanda ya dawo daga Maiduguri jiya, zai halarci taron.
Bello, who returned from Maiduguri yesterday, will attend the meeting. (careful speech or writing)
Hauwa, wadda take kula da asusun, tana son ganin rasit ɗin.
Hauwa, who manages the account, wants to see the receipt. (careful speech or writing)
Bello da Hauwa, waɗanda suka wakilci ƙungiyar, sun gabatar da rahoto.
Bello and Hauwa, who represented the association, presented a report. (careful speech or writing)
In speech, a pause and a separate intonational phrase support the parenthetical interpretation. In writing, commas conventionally represent that phrasing, but punctuation cannot turn an unidentified common noun into an established referent by itself.
The agreeing form is not invariant da with gender morphology attached. Wanda/wadda/waɗanda are full relative forms used in headed restrictions, headless relatives, and nonrestrictive relatives. With an established antecedent and parenthetical phrasing, they make the appositive relation especially transparent.
The interpretation changes truth conditions
Restrictive and nonrestrictive readings do more than change style. Compare the following classroom report:
Ɗaliban da suka kawo kati sun shiga ɗakin.
The students who brought a card entered the room. (only the card-bearing subset is asserted to have entered)
Ɗaliban, waɗanda suka kawo katunansu, sun shiga ɗakin.
The students, who brought their cards, entered the room. (the already identified students are all described as card-bearing)
The first sentence leaves open what happened to students without cards. The second presents card-bearing as supplementary information about the whole established group. English makes a similar distinction, but Hausa does not simply copy English comma placement: the noun's discourse status, prosody, relative frame, and TAM all matter.
Quantifiers make the contrast especially important. Ma’aikatan da suka samu horo selects trained employees. By contrast, a parenthetical about an already fixed group makes the added property apply to that group rather than creating a smaller subset.
TAM in canonical restrictions and appositives
Canonical affirmative restrictive relatives select relative completive muka/kuka/suka/aka and relative continuative nake/kake/.../suke/ake:
Rahoton da muka karanta ya bayyana matsalar sosai.
The report that we read explained the problem clearly.
Compare the same proposition as an independent assertion:
Mun karanta rahoton, kuma ya bayyana matsalar sosai.
We read the report, and it explained the problem clearly. (plain independent clause)
The restriction has relative muka, while the main assertion has plain mun. Appositive relatives permit more variation. Relative TAM is fully acceptable in Bello, wanda muka gani jiya, ...; some speakers also use a plain-TAM clause after agreeing wanda/wadda/waɗanda, especially when it feels like a loose discourse continuation. A visible plural contrast is waɗanda suka... versus variant waɗanda sun.... Do not extend that variation to the canonical compact restrictive pattern.
Gaps and resumptives do not determine restrictiveness
Both interpretations can contain direct-object gaps or overt resumptive material. A restrictive locative relative may resume its head:
Mun koma gidan da muka taɓa zama a cikinsa.
We returned to the house in which we once lived.
An appositive possessor relative does the same kind of work:
Audu, wanda motarsa ta lalace a hanya, ya iso da bas.
Audu, whose car broke down on the road, arrived by bus. (careful speech or writing)
Masculine -sa in motarsa resumes Audu, while feminine mota controls ta. These internal relations say nothing by themselves about whether the clause restricts or merely comments. That distinction comes from the larger discourse configuration.
Ambiguity and editorial choices
Some definite descriptions can be used either to select or to refer uniquely in context. Shugaban da ya yi jawabi normally means “the leader who gave a speech,” selecting one leader. If the organization has one salient leader and the speech is parenthetical news, careful prose can prefer shugaban ƙungiyar, wanda ya yi jawabi, .... This is not a purely mechanical alternation because the second noun phrase contains a possessive identification and presents the person as established.
In fast (informal) speech, pauses may be weak and listeners rely heavily on context. In edited (formal) prose, choose the construction and punctuation that make the intended scope explicit. Do not rely on a comma to rescue an otherwise contradictory noun phrase.
Common Mistakes
1. Leaving the restrictive head unlinked
❌ mota da muka saya tana wurin gyara
Incorrect compact restrictive frame—mota needs joined -r.
✅ motar da muka saya tana wurin gyara
The car that we bought is at the repair shop.
2. Mixing the linked da frame with the complex relative-pronoun frame
❌ macen wadda take kula da ofishin
Incorrect mixture for the intended compact restriction—linked macen belongs with invariant da.
✅ macen da take kula da ofishin
The woman who manages the office.
Use either macen da... or a coherent indefinite frame such as wata mace wadda..., not a blend of the two.
3. Using plain TAM in a canonical restriction
❌ mutanen da sun halarci taron
Incorrect canonical restrictive relative—sun is plain completive.
✅ mutanen da suka halarci taron
The people who attended the meeting.
4. Treating punctuation as the only difference
❌ Wata ma’aikaciya, da ta kira ni, za ta dawo.
Incorrect careful appositive packaging—bare da after this indefinite antecedent does not establish the intended parenthetical relation.
✅ Zainab, wadda ta kira ni, za ta dawo.
Zainab, who called me, will return. (careful speech or writing)
5. Repeating an object in a reduced relative-TAM appositive
❌ Rahoton, wanda muka karanta shi jiya, ya yi tsawo.
Incorrect canonical object relation—the final shi repeats the direct-object gap.
✅ Rahoton, wanda muka karanta jiya, ya yi tsawo.
The report, which we read yesterday, was long. (careful speech or writing)
This reduced relative-TAM pattern has an object gap. Looser appositive clauses with plain TAM may retain an overt object pronoun for some speakers, so the warning is not a ban on every resumptive object in every appositive construction.
Key Takeaways
- Restrictive relatives help identify a referent; nonrestrictive relatives add information about one already established.
- A compact restriction uses linked head + invariant da + relative TAM; a second restrictive frame uses a bare or indefinite head plus agreeing wanda/wadda/waɗanda.
- Agreeing wanda/wadda/waɗanda can introduce a headed restriction, stand headlessly, or package an appositive continuation.
- The distinction affects interpretation and scope, not just punctuation or formality.
- Gaps and resumptives express grammatical roles inside either type; they do not decide restrictiveness.
- Plain-TAM variants reported in appositives do not license plain TAM in canonical restrictive relatives.
