Some Hausa words visibly repeat material but no longer have a meaning that speakers calculate afresh each time. Forms such as kala-kala “of various kinds,” iri-iri “of various types,” daban-daban “different from one another / various,” and sannu-sannu “slowly, little by little” are conventional pieces of the vocabulary. Their repeated shape still contributes an idea such as variety, plurality, or gradual progression, but their exact use must be learned.
This is the boundary between productive grammar and the lexicon. A productive pattern lets speakers create a form whose meaning is predictable in context; a lexicalized form has become established enough that its meaning, category, collocations, or spelling is partly stored. The boundary is gradual, not a switch.
Transparent shape, conventional meaning
Three common formations remain semantically transparent:
| Base | Established repeated form | Usual contribution |
|---|---|---|
| kala “kind; colour” | kala-kala | many different kinds or colours |
| iri “kind, type” | iri-iri | various types |
| daban “separate, different” | daban-daban | various; mutually different |
| sannu “gently; an expression of greeting or sympathy” | sannu-sannu | slowly; little by little |
Shagon yana sayar da yadudduka kala-kala.
The shop sells fabrics of many different colours and kinds.
Mun tattauna hanyoyi iri-iri na rage kuɗin aiki.
We discussed various ways of reducing operating costs.
Ra’ayoyinmu daban-daban ne, amma mun cim ma matsaya ɗaya.
Our views are different, but we reached one conclusion.
These are transparent because the repeated shape and the notion of multiplicity still match. They are lexicalized because speakers do not treat every synonymous noun or adjective as freely replaceable in the same template. English can say “all kinds,” “various,” or “different,” but it gives no reliable clue as to which Hausa base has an established repeated form.
The repeated form can change category or function
The base kala is a noun, while kala-kala commonly functions as a modifier or manner-like expression. Sannu occurs independently in greetings and expressions of sympathy, but sannu-sannu is a conventional adverb meaning “slowly” or “little by little.” The output therefore need not preserve the English grammatical category associated with the base.
Wannan kala ya fi dacewa da ɗakin.
This colour suits the room better.
An yi wa ɗakunan fenti kala-kala.
The rooms were painted in various colours.
The pair contrasts the base kala with the established repeated form kala-kala. In the first sentence, kala identifies one colour. In the second, kala-kala describes diversity across rooms. It is not simply the plural of kala.
Sannu da aiki, Hajiya Amina.
Well done with the work, Hajiya Amina.
Ka juya murfin sannu-sannu kada ya karye.
Turn the lid slowly so that it does not break.
English “slowly” is an adverb derived with -ly. Hausa does not preserve that English category-building method: the whole repeated expression supplies the adverbial meaning. This is why translating the pieces separately can mislead.
Lexicalized does not mean fully predictable
The form sannu-sannu is the clearest blocked case on this page. Once it means “slowly, gradually,” a learner cannot infer that any greeting or sympathy formula may be doubled to produce an adverb. Nor does sannu-sannu mean “many greetings.” Its conventional adverbial use must be stored as a unit.
Sannu-sannu aka gyara tsohuwar makarantar, ba a rana ɗaya ba.
The old school was renovated little by little, not in a single day.
The interpretation here is gradual progression. Repetition of sannu is not being created online to count separate instances. The same caution applies to daban-daban: its common meaning is “various / different from one another,” not mechanically “twice separate.”
This does not prevent wordplay. In (literary) prose or advertising, a writer may exploit the visible relationship between a base and a repeated form. Such creativity depends on the established lexical meaning; it does not prove that unrestricted reduplication is available for every word.
How lexicalization differs from productive distribution
Productive distributive reduplication answers questions such as “how many per person?” or “in what sequence?” Thus biyu-biyu means “two each / in twos,” and gida-gida can mean “house by house.” The numeral or count noun supplies a value that remains clearly recoverable.
Daliban sun shiga biyu-biyu.
The students entered two at a time.
Jami’an lafiya sun zagaya gida-gida.
The health workers went around house by house.
By contrast, iri-iri and kala-kala conventionally describe variety. They do not assign one iri or one kala to each participant. Compare the productive patterns on reduplication for distribution with the vocabulary-centered patterns here.
Phonological identity and written form
In the forms covered here, the second member normally repeats the ordinary boko form: iri-iri, kala-kala, daban-daban, sannu-sannu. A hyphen marks the close repeated relationship. Hausa tone and vowel length help distinguish words in speech, but ordinary boko does not mark them; this page therefore does not invent tone marks from spelling.
The hyphen is not a pause instruction. In fluent speech, kala-kala is one tight prosodic expression. Nor should a writer remove the hyphen because English writes “various” as one word. Hausa orthographic convention, not English appearance, controls the form.
An kawo kayan ado iri-iri domin bikin.
Various kinds of decorations were brought for the celebration.
Limits on coinage
Speakers can extend reduplicative patterns in suitable discourse, but acceptability depends on the input category, the intended reading, and convention. A numeral readily supports a distributive reading; an adjective may support intensity in an appropriate construction; a noun does not automatically gain the lexical meaning “various kinds of X” merely by being copied.
That restriction matters for advanced reading. Encountering two similar syllable sequences does not prove synchronic reduplication either. A historically repeated form may have become opaque, and an accidental recurring segment may never have involved copying. Productivity must be demonstrated by contemporary contrasts and possible new formations, not guessed from visual resemblance.
Common Mistakes
1. Separating an established reduplicated expression.
❌ Shagon yana sayar da yadudduka kala kala.
Incorrect standard spelling here — the conventional repeated form is hyphenated.
✅ Shagunan nan suna sayar da kaya kala-kala.
These shops sell goods of many different kinds.
2. Treating a lexicalized form as an ordinary plural.
❌ Kala-kala sun yi tsada.
Incorrect for ‘the colours are expensive’ — kala-kala is not the regular plural noun required here.
✅ Launuka sun yi tsada.
The colours are expensive.
3. Reading sannu-sannu as repeated greetings.
❌ Ya yi mini sannu-sannu biyu.
Incorrect for ‘he greeted me twice’ — sannu-sannu has the conventional adverbial meaning ‘slowly.’
✅ Ya gaishe ni sau biyu.
He greeted me twice.
4. Copying any noun to mean “various.”
❌ Mun sayi kujera-kujera.
Incorrect for the intended meaning ‘we bought various chairs’ — this coinage is not licensed by the lexicalized pattern.
✅ Mun sayi kujeru iri-iri.
We bought various kinds of chairs.
5. Preserving an English category instead of using the Hausa unit.
❌ Ya buɗe ƙofar cikin slow.
Incorrect code-mixed structure in neutral Hausa — use the established Hausa adverbial expression.
✅ Ya buɗe ƙofar sannu-sannu.
He opened the door slowly.
Key Takeaways
- Kala-kala, iri-iri, daban-daban, and sannu-sannu have recognizable repeated shapes but conventional meanings and functions.
- A repeated form is not automatically a plural; it may express variety, contrast, gradualness, intensity, or distribution.
- Sannu-sannu is lexically restricted: its meaning “slowly / little by little” cannot be generated by freely doubling comparable expressions.
- Standard boko hyphenates these close reduplicated units.
- Contemporary evidence must establish productivity; visual repetition alone does not justify a new Hausa word.
