Some Hausa plurals repeat part of a noun: jaka → jakunkuna “bag(s),” bashi → basussuka “debt(s),” and littafi → littattafai “book(s).” Linguists call this reduplication. The copied material may be only a consonant-and-vowel sequence, and sound rules can disguise what was copied, so the result is rarely as simple as saying the whole singular twice.
These patterns are neutral in Nigerian Standard Hausa. They are valuable for recognizing related forms, but they are not a productive instruction that learners can apply to every noun.
What reduplication looks like
The most useful division is between partial reduplication, where only part of the stem is repeated, and full reduplication, where a whole form is repeated. Partial reduplication is much more important in the inherited plural system.
| Singular | Gender | Plural | Meaning | Visible pattern |
|---|---|---|---|---|
| jaka | feminine | jakunkuna | bag(s) | partial repetition with -una |
| bashi | masculine | basussuka | debt(s) | partial repetition with -uka |
| cuta | feminine | cututtuka | illness(es) | partial repetition with -uka |
| gari | masculine | garuruwa | town(s) | partial repetition with -uwa |
| ƙashi | masculine | ƙasusuwa | bone(s) | partial repetition with -uwa |
| littafi | masculine | littattafai | book(s) | internal repetition plus -ai |
Na ɗauki jaka ɗaya; sauran jakunkuna suna cikin mota.
I took one bag; the other bags are in the car.
Basussuka sun yi yawa, don haka ya fara biyan su a hankali.
The debts became numerous, so he began paying them gradually.
Likita ya ce waɗannan cututtuka ana iya kare kai daga gare su.
The doctor said that these illnesses can be prevented.
The repeated portion is not always transparent in modern pronunciation. Historical sound changes can turn an expected sequence into a doubled consonant or another surface shape. That is why bashi → basussuka and ƙashi → ƙasusuwa resemble each other without being produced by a simple spelling rule.
Reduplication can accompany different endings
English-speaking learners often imagine that repetition itself is “the plural ending.” In Hausa, repetition commonly works together with a plural vowel pattern or suffix. Littattafai combines internal repetition with a final -ai shape; jakunkuna combines partial repetition with -una; cututtuka combines it with -uka.
Na sayi littafi ɗaya, amma ɗan’uwana ya sayi littattafai uku.
I bought one book, but my brother bought three books.
Garuruwa da yawa sun samu ruwan sama a daren jiya.
Many towns received rain last night.
There is no rule saying that every noun of the same length must choose the same combination. Riga “gown” has riguna, without the internal repetition seen in jaka → jakunkuna. Gida “house” has gidaje, not a reduplicated plural. The noun’s lexical class selects the whole formation.
Full repetition is a limited pattern
Full repetition also occurs, especially with some loans and lexicalized formations: scholarly descriptions cite joji → joji-joji “judge(s).” Other repeated noun forms can have distributive or sequential meanings rather than being ordinary plurals. For example, gida-gida means “house by house,” while the normal count plural of gida is gidaje. The page on multiple plurals and meaning differences separates those constructions.
This distinction matters: a hyphenated repeated form is not automatically the plural of any Hausa noun. Full repetition is a limited lexical pattern (neutral where established) and a productive source of distributive expressions; those are different grammatical facts.
Gender and agreement
Reduplication changes number, not the stored gender of the singular. Jaka and cuta are feminine singular; bashi, gari, ƙashi, and littafi are masculine singular. Their plurals all use the common plural agreement series.
Wannan jaka ce, amma waɗannan jakunkuna ne.
This is a bag, but these are bags.
Wannan littafi ne; waɗannan littattafai ne.
This is a book; these are books.
The English meaning cannot tell you Hausa gender. “Bag” has no grammatical gender in English, but Hausa jaka controls feminine singular agreement. Once plural, jakunkuna takes waɗannan, sun, and ne, just like plurals whose singulars are masculine.
Definite and linked forms
The definite or genitive-linked plural uses the plural -n series. In analysis one may show a boundary, such as jakunkuna + -n. Ordinary boko joins the result: jakunkunan.
| Bare plural | Definite/linked form | Natural linked phrase |
|---|---|---|
| jakunkuna | jakunkunan | jakunkunan ɗalibai “the students’ bags” |
| basussuka | basussukan | basussukan kamfani “the company’s debts” |
| cututtuka | cututtukan | cututtukan yara “children’s illnesses” |
| garuruwa | garuruwan | garuruwan Arewa “northern towns” |
| littattafai | littattafan | littattafan makaranta “schoolbooks” |
Jakunkunan ɗalibai suna kusa da ƙofar aji.
The students’ bags are near the classroom door.
Littattafan makaranta sun iso da safe.
The schoolbooks arrived in the morning.
The stem’s final shape determines how the joined form surfaces. Jakunkuna → jakunkunan is straightforward, but littattafai → littattafan loses the final i before -n. Reduplication and linker phonology are separate layers; neither can be guessed from English.
Indefinite introduction and definite return
An kawo wasu jakunkuna zuwa ofis. Jakunkunan suna ɗauke da takardun jarabawa.
Some bags were brought to the office. The bags contain the examination papers.
The first mention wasu jakunkuna introduces an unidentified set. The second mention jakunkunan points back to that discourse-given set. Reduplication supplies plural number; joined -n supplies the definite reading. One does not replace the other.
Common Mistakes
1. Confusing a similar-looking lexical plural with the required one.
❌ Na sa tufafi cikin jakuna.
Incorrect for the intended meaning — jakuna means ‘donkeys,’ not ‘bags.’
✅ Na sa tufafi cikin jakunkuna.
I put the clothes in bags.
2. Omitting the repeated material.
❌ Basuka sun yi yawa.
Incorrect here — the standard plural of bashi is basussuka.
✅ Basussuka sun yi yawa.
The debts are numerous.
3. Keeping feminine singular agreement after pluralization.
❌ Waɗannan jakunkuna ce.
Incorrect — jakunkuna is plural and takes ne.
✅ Waɗannan jakunkuna ne.
These are bags.
4. Leaving the plural unlinked before a possessor.
❌ littattafai yara
Incorrect for ‘the children’s books’ — a linker is required.
✅ littattafan yara
the children’s books
Key Takeaways
- Hausa partial reduplication usually works together with another plural pattern: jaka → jakunkuna, cuta → cututtuka, littafi → littattafai.
- Sound history can obscure the copied material, so spelling alone cannot generate a reliable plural.
- Full repetition is limited as ordinary plural formation and may instead signal distribution, as in gida-gida “house by house.”
- The singular keeps lexical gender, while all plurals take common plural agreement and plural -n for definiteness or linking.
