Hausa duk/duka presents a set or quantity as complete: duk yaran “all the children,” yaran duka “all the children,” and duniya duka “the whole world.” It does not agree for gender or number. Instead, the noun phrase determines whether the clause is masculine singular, feminine singular, or plural, while position and context determine whether English prefers all, the whole, or occasionally every.
All unlabelled forms and examples here are (neutral Nigerian Standard Hausa). Both duk and duka are ordinary across conversation and writing; some fixed expressions favor one position or form.
The two basic positions
The most useful beginner pattern is duk + noun phrase before the noun and noun phrase + duka after it:
| Position | Pattern | Example | Meaning |
|---|---|---|---|
| before the noun phrase | duk + NP | duk yaran | all the children |
| after the noun phrase | NP + duka | yaran duka | all the children |
| after a possessed phrase | possessed NP + duka | ’ya’yansa duka | all his children |
| with a pronominal set | duk + linker + pronoun | dukansu | all of them |
Duk yaran sun shiga aji.
All the children went into the classroom.
Yaran duka sun shiga aji.
All the children went into the classroom.
The two sentences have essentially the same truth conditions in a neutral context: no member of the relevant group was left out. Post-nominal duka can make the completed set feel especially clear, but it is not a gender or plural ending.
’Ya’yansa duka suna zaune a Kano.
All his children live in Kano.
Na kira su, kuma dukansu sun amsa.
I called them, and all of them answered.
In dukansu, the sequence is written as one word. It refers back to a known plural group. Comparable forms include dukanmu “all of us” and dukanku “all of you.”
That is a strong production pattern, not an absolute division into two different words: duka can also occur before a noun phrase. For reliable neutral learner usage, start with duk + NP and NP + duka, then learn wider pre-nominal duka from exposure.
Definiteness decides which set is complete
Hausa has no separate article directly parallel to English the. A bare plural with duk can make a general statement or receive a contextually restricted reading. A definite or demonstrative phrase explicitly identifies a known set.
| Phrase | Typical interpretation |
|---|---|
| duk yara | all children generally, or all relevant children by context |
| duk yaran | all the known children |
| yaran nan duka | all these / those salient children |
| duk waɗannan yara | all these children, explicitly selected |
A makaranta, duk yara suna da haƙƙin koyo.
At school, all children have the right to learn.
Duk yaran sun dawo daga makaranta.
All the children have returned from school.
Yaran nan duka sun karɓi littattafai.
All these children received books.
In yaran nan duka, yaran nan is already a complete demonstrative noun phrase: linked plural yaran plus nan. Post-nominal duka quantifies over that whole selected set. Do not remove the linker from yaran nan merely because another word follows.
The linked pre-nominal form dukkan is also common with a delimited set: dukkan yaran “all of the children.” It contains the -n linker, with the resulting kk written as part of the same word; it is not a gender or plural agreement form.
An yi wa dukkan yaran rigakafi.
All the children were vaccinated.
Plural sets, mass quantities, and bounded wholes
With a plural count noun, duka normally includes every member of the set. It also exhausts a mass quantity. Some singular nouns conventionally construed as total domains or sums of parts—notably duniya “world” and jiki “body”—allow a post-nominal whole reading. This does not make duka a mechanical translation of English whole before or after every singular count noun.
| Noun phrase | Number/gender | Agreement | Interpretation |
|---|---|---|---|
| jikinsa duka | masculine singular whole | ya / yana | his whole body |
| duniya duka | feminine singular totality | ta / tana | the whole world |
| gidajen duka | plural | sun / suna | all the houses |
Jikinsa duka ya cika da kuraje.
His whole body was covered in a rash.
Duniya duka ta ji labarin.
The whole world heard the news.
Gidajen duka sun samu wutar lantarki.
All the houses got electricity.
For an ordinary concrete singular, gaba ɗaya is often the safer whole expression: gidan gaba ɗaya “the whole house,” motar gaba ɗaya “the whole car.” Number and the lexical construal of the noun matter; do not build every English whole N phrase by adding duka.
Mass nouns also allow complete-quantity readings:
Yaran sun sha ruwan duka.
The children drank all the water.
Here there are not separate countable waters. Duka exhausts the contextually available amount.
Collective completion versus individual distribution
Duk/duka is especially natural when the group acts collectively or when the sentence simply says that the whole set participated. This differs from kowane/kowace, which considers members one by one.
The individual-by-individual pattern is developed on kowane and kowace.
Duk ɗaliban sun taru a gaban makaranta.
All the students gathered in front of the school.
Gathering is a group event. It cannot normally be predicated of one student at a time with the same meaning. By contrast, kowane ɗalibi ya kawo littafi “each student brought a book” distributes the action to individuals.
The plural agreement in duk ɗaliban sun taru belongs to ɗaliban, not to duk. The quantifier itself never changes to match masculine, feminine, or plural nouns.
When English every appears
Some Hausa expressions with duk are naturally translated with English every, especially repeated times or the emphatic frame duk wani/wata “each and every / any.” That does not make duk a gender-agreeing determiner.
Yana kiran mahaifiyarsa duk ranar Juma’a.
He calls his mother every Friday.
Za mu binciki duk wata takarda kafin mu yanke shawara.
We will examine every single document before making a decision.
In duk wata takarda, feminine wata agrees with takarda; duk remains unchanged. The ordinary distributive equivalent is kowace takarda. The duk wani/wata construction is stronger and often means “every single” or “any whatsoever,” depending on context.
Scope under negation: not all is not none
When negation has scope over a duk phrase, the normal meaning is “not all.” At least one member may still satisfy the positive statement.
Ban karanta duk littattafan ba.
I did not read all the books.
This does not say that no book was read. To make “none” explicit, Hausa uses a different negative strategy rather than assuming that duk changes meaning.
Ba duk baƙin ne suka zo ba.
Not all the guests came.
The focus frame makes the scope clear: the complete set did not participate. Some guests may have come.
A short exchange about a complete set
A: Yaran sun dawo? B: Eh, dukansu sun dawo. A: Har da Aisha? B: Eh, yaran duka suna gida yanzu.
A: Have the children returned? B: Yes, all of them have. A: Including Aisha? B: Yes, all the children are at home now.
The first question establishes a definite group. Dukansu retrieves that group pronominally, and yaran duka states its complete inclusion. The exchange, not an English article, supplies the reference set.
Common Mistakes
1. Making duka agree with a feminine noun.
❌ duniya dukar
Incorrect — duka does not take feminine agreement.
✅ duniya duka
The whole world.
2. Using singular clause agreement because duk is a single word.
❌ Duk yaran ya dawo.
Incorrect — the quantified noun is plural.
✅ Duk yaran sun dawo.
All the children returned.
3. Using duk with a bare singular count noun as the neutral phrase for every.
❌ duk littafi
Not the neutral noun phrase for ‘every book’ — ordinary individual distribution uses kowane.
✅ kowane littafi
Every book.
For emphatic “each and every child,” use duk wani yaro, not bare duk yaro as the beginner default.
4. Omitting the linker inside a demonstrative set.
❌ yara nan duka
Incorrect — post-nominal nan requires the linked plural form.
✅ yaran nan duka
All these children.
5. Interpreting a negative duk sentence as none.
❌ Ban duba duk takardun ba.
Incorrectly interpreted as ‘I checked none of the documents’ — the sentence means that the checking did not cover the whole set.
✅ Na duba wasu takardu, amma ban duba dukansu ba.
I checked some documents, but I did not check all of them.
Key Takeaways
- Duk commonly precedes a noun phrase; duka commonly follows it.
- The quantifier is invariant. The noun controls masculine, feminine, or plural agreement.
- With a plural, the meaning is usually “all members”; certain singular totalities allow a conventional “whole” reading.
- Bare, definite, and demonstrative noun phrases define different reference sets.
- Duk/duka allows collective readings; kowane/kowace is distributive.
- Under ordinary negation, “not all” does not mean “none.”
