Most Hausa derivatives display the ending and tone of one grade at a time: a word cannot normally end simultaneously in Grade 4 -e and Grade 6 -o. A small but important set nevertheless preserves evidence of extension stacking, where one derivational layer builds on another and the outer layer supplies the surface grade shape. This refines the basic account of what a Hausa verb grade is. The clearest standard example is the family ja → janye → janyo: “pull,” “pull away/withdraw,” and “draw toward the center or attract.”
All unlabelled examples are (neutral Nigerian Standard Hausa). Ordinary boko has no tone or vowel-length marks. Technical marked forms in older linguistic sources use different transcription conventions; this page therefore states tone patterns with H and L rather than copying historical spellings into ordinary examples.
What “stacking” does and does not mean
In a simple derivative, a base combines with one extension. In a stacked analysis, a derivative itself becomes the input to another extension.
| Stage | Form | Contribution | Status |
|---|---|---|---|
| basic verb | ja | pull, draw | high-frequency lexical base |
| first extension | janye | pull away, withdraw, remove | established Grade 4 relative |
| outer extension | janyo | draw toward; attract; bring about | established form with Grade 6 surface shape |
The inner Grade 4 contribution is visible not as a surviving final -e, but in the expanded stem jany-. The outer Grade 6 contribution supplies long -o and the all-High melody. This is why stacking is clearest with monosyllabic roots and other formations that retain extra consonantal material: if both extensions were represented only by tone and one final vowel, the surface word could not display both independently.
Ka ja akwatin zuwa gefen bango.
Pull the box toward the wall. (basic ja)
Jami’in ya janye takardar bayan ya gano kuskure.
The official withdrew the document after discovering an error. (Grade 4 janye)
Sabon shirin ya janyo hankalin matasa da yawa.
The new program attracted the attention of many young people. (stacked/extended janyo)
The three forms are related, but none is just an inflection of another. Janye is not a past form of ja, and janyo is not selected merely because the object is nearby.
Janyo across four object environments
Because the outer layer has Grade 6 shape, janyo is formally stable with no following object, a noun object, a direct-object pronoun, and an indirect object.
| Environment | Example | Analysis |
|---|---|---|
| no following object | Na riƙe igiyar, shi kuma ya janyo. | the rope is understood |
| noun direct object | Ya janyo kujerar zuwa inuwa. | kujerar is the moving theme |
| direct-object pronoun | Ya janyo ta zuwa inuwa. | ta replaces a feminine noun |
| indirect object | Ya janyo mini kujerar. | mini is beneficiary; kujerar is theme |
Na riƙe ƙarshen igiyar, shi kuma ya janyo a hankali.
I held the end of the rope, and he pulled it toward himself slowly. (no following object)
Ya janyo kujerar zuwa ƙarƙashin bishiyar.
He pulled the chair into the shade under the tree. (noun direct object)
Kujerar ta yi nauyi, amma ya janyo ta shi kaɗai.
The chair was heavy, but he pulled it over by himself. (direct-object pronoun)
Da aka fara ruwa, ya janyo mana kujerun zuwa cikin rumfar.
When it began to rain, he pulled the chairs into the shelter for us. (indirect object mana)
The same form also has a conventional abstract use, especially in collocations such as janyo hankali “attract attention,” janyo matsala “cause a problem,” and janyo asara “cause a loss.” That lexicalization does not erase the layered morphology.
Further evidence—and why it needs labels
The classic linguistic description records other combinations, including a Grade 4 totality layer followed by Grade 7, and causative or reversive material followed by Grade 6. Forms in the literature include a counterpart of shanye “drink up” with final -u, meaning roughly “be completely drunk/consumed,” and forms in the maida/maido “return, restore/bring back” family. Some of the cited reversive formations are (regional or historical) rather than safe Nigerian Standard production models.
Modern maido is common, but a learner should store its attested senses and frames rather than assume that its entire history is synchronically transparent.
Kotun ta bayar da umarnin a maido da rajistar ƙungiyar.
The court ordered that the organization's registration be restored. (formal/news register)
Ki maido mini littafin idan kin gama karantawa.
Bring the book back to me when you finish reading it.
The visible -o supports a ventive analysis: the item or state is restored toward a relevant center. The preceding material is connected with a return/restoration family. However, speakers do not have to construct the word by consciously applying two rules whenever they say it.
Historical descriptions also mention “double causatives.” Those forms are valuable evidence that derivation can apply to derived input, but some belong to older or dialect-specific systems. They should not be presented beside ordinary modern forms without labels, and they should never be used as a recipe for inventing a new Nigerian Standard verb.
Why unrestricted stacking is impossible on the surface
Grades 4, 6, and 7 normally express themselves through integrated tone plus a final vowel. If Grade 4 applies and then Grade 6 applies, the Grade 6 melody and final vowel override the Grade 4 surface ending. Only residual stem material, lexical meaning, or comparison with a related form can reveal the inner layer.
This creates a methodological problem. A sequence that appears to contain two extensions may have several analyses:
- a synchronically layered derivative;
- a formerly layered word now stored as one lexeme;
- a historically related family whose intermediate step is no longer active;
- an accidental resemblance.
The spelling alone cannot decide. Janyo is a strong case because ja and janye are both established and the semantic path is coherent. A newly imagined chain without dictionary or corpus evidence is not comparable.
Stacking is derivation, not object inflection
Object-conditioned A/B/C/D forms operate inside the surface grade. They do not add another grade. In ya janyo ta, the direct pronoun ta selects the pronoun-object environment, but janyo remains the invariant Grade 6-shaped lexeme. In ya janye takardar, by contrast, choosing janye instead of janyo changes the derivative and the event construal.
Kamfanin ya janye tayin bayan an ƙi sharuddan.
The company withdrew the offer after the conditions were rejected.
Tayin ya janyo ce-ce-ku-ce a tsakanin ma’aikata.
The offer provoked controversy among the employees.
Nor does TAM select a layer. Completive ya janyo, future zai janyo, and continuative yana janyo matsala contain the same lexical derivative.
Wannan sauyin zai janyo ƙarin aiki ga ma’aikatan.
This change will create additional work for the employees.
Sauyin yana janyo mana matsala a kullum.
The change causes us problems every day.
With no local object, the weak verbal noun is janyowa: yana janyowa “he is pulling it over.” Before a local object, -wa is absent: yana janyo kujera. That -wa alternation belongs to the verbal-noun construction; it is not a third stacked lexical extension.
Productivity is lexical and uneven
The grade system makes semantic combinations imaginable: totality plus ventive, causation plus ventive, totality plus result. Actual Hausa realizes only some combinations, and even those may be conventionalized. Phonological room, semantic coherence, lexical frequency, dialect, and historical survival all matter.
English-speaking learners may expect derivation to behave like a transparent sequence of particles—pull + away + here. Hausa often compresses the result into one word and lets the outer pattern replace the inner ending. The gain is morphological compactness; the cost is that the layers are not always recoverable without lexical evidence.
Practice
For ja, janye, janyo, identify the event contribution at each step. Then change only the object environment of janyo: ya janyo; ya janyo kujera; ya janyo ta; ya janyo mini kujera. Finally, contrast lexical choice under the same completive TAM: ya ja igiyar, ya janye takardar, ya janyo hankali. The preverbal marker stays the same while derivation and valency change.
Common Mistakes
1. Reading janye and janyo as tense forms of ja.
❌ Janye shi ne lokacin da ya wuce na ja, janyo kuma shi ne na gaba.
Incorrect—janye and janyo are lexical derivatives, not past and future forms.
✅ Gobe zai janye takardar idan sharuɗɗan ba su canza ba.
Tomorrow he will withdraw the document if the conditions do not change.
2. Treating stacking as free concatenation.
❌ Ana iya jera kowace Grade 4, 5, 6, da 7 ba tare da duba amfani ba.
Incorrect claim—extension combinations are restricted and lexically attested.
✅ Sabon talla ya janyo hankalin kwastomomi.
The new advertisement attracted customers' attention. (established janyo)
3. Keeping the inner final vowel before the outer extension.
❌ Ya janye-o kujerar zuwa nan.
Incorrect invented form—the outer Grade 6 pattern yields janyo, not a sequence of two written endings.
✅ Ya janyo kujerar zuwa nan.
He pulled the chair over here.
4. Calling weak -wa another lexical extension.
❌ Yana janyowa kujera, domin wa ita ce Grade ta uku a jeri.
Incorrect—the weak verbal-noun -wa is omitted before a local object and is not a stacked grade.
✅ Yana janyo kujera zuwa cikin ɗaki.
He is pulling a chair into the room.
Key Takeaways
- Extension stacking exists, but it is exceptional and lexically constrained rather than freely combinable.
- Ja → janye → janyo is the clearest attested teaching family: base, separation/totality relative, then ventive outer shape.
- The outer extension determines surface tone and final vowel; retained stem material and meaning may reveal the inner layer.
- Object environments and weak verbal-noun -wa are not additional lexical grades.
- Regional, historical, and rare stacked forms require explicit labels; never create a new derivative from semantic plausibility alone.
