The derived grades give Hausa speakers recognizable semantic resources: Grade 4 often profiles totality or separation, Grade 5 is commonly causative, Grade 6 is ventive, and Grade 7 presents an affected result or capacity. Yet frequent derivatives can acquire meanings that are narrower, broader, or more abstract than those labels predict. Such a form is lexicalized when speakers must know its conventional meaning and argument frame as part of the word, an extension of the principle introduced under lexical exceptions to grade predictions.
All unlabelled examples are (neutral Nigerian Standard Hausa). Ordinary boko omits tone and vowel length. In (academic) descriptions below, Grade 4 has an H-L-(H) melody and final -e, Grade 5 is all High with -ar or related object forms, Grade 6 is all High with long -o, and Grade 7 has final -u with preceding Low and final High tone. Those technical patterns help classify a word; they do not constitute a word-for-word translation.
Productive pattern and lexical entry are two layers
A grade meaning can be transparent, metaphorically extended, or strongly conventionalized. These are points on a continuum, not three mechanically separable boxes.
| Extended verb | Grade | Established meaning | Relation to the broad grade meaning |
|---|---|---|---|
| shanye | 4 | drink up, consume completely | transparent totality |
| jawo | 6 | pull toward; cause, bring about | spatial use plus conventional metaphor |
| tuno | 6 | recall, remember | bringing something back to mind |
| faru | 7 | happen, occur | lexicalized event coming about |
| gamu da | 7 | meet, encounter | lexicalized and obligatorily framed with da |
| yiwu | 7 | be possible | strongly conventionalized possibility predicate |
Ya shanye ruwan kwalbar kafin ya hau mota.
He drank all the water in the bottle before getting into the car. (transparent Grade 4 totality)
Tsarin da bai kammala ba ya jawo tsaiko mai tsawo.
The incomplete plan caused a long interruption. (conventional abstract Grade 6 jawo)
Ban tuno da sunan otal ɗin ba sai da muka isa tashar.
I did not remember the hotel's name until we reached the station. (lexicalized sociative Grade 6 tuno da)
Me ya faru bayan wutar lantarki ta ɗauke?
What happened after the electricity went out? (lexicalized Grade 7 faru)
English does the same kind of lexical work with grasp an idea or run a company: the metaphor is intelligible, but speakers still learn the established expression. The difference is that Hausa also packages the derivative in a recurrent tone-and-final-vowel pattern.
One lexicalized extension in four environments
Grade 6 jawo retains long -o and its all-High melody across object environments. What changes is the syntax and, sometimes, which established sense sounds natural.
| Environment | Example | Reading |
|---|---|---|
| no following object | Mun yi hasara; jinkirin ne ya jawo. | We made a loss; the delay caused it. |
| noun direct object | Jinkirin ya jawo matsala. | The delay caused a problem. |
| direct-object pronoun | Jinkirin ya jawo ta. | The delay caused it. (feminine referent) |
| indirect object | Ya jawo mini kujerar. | He pulled the chair over for me. |
Mun yi asara; jinkirin jigilar ne ya jawo.
We made a loss; it was the shipping delay that caused it. (no following object; effect recovered from discourse)
Jinkirin jigilar ya jawo matsala ga shagunan yankin.
The shipping delay caused a problem for the shops in the area. (noun object)
Matsalar ta ƙaru, amma jinkirin bai jawo ta shi kaɗai ba.
The problem grew, but the delay alone did not cause it. (direct-object pronoun)
Don Allah ka jawo mini kujerar nan.
Please pull that chair over for me. (indirect object mini)
The abstract “cause” sense is natural in the first three. The literal pulling sense makes the beneficiary in the fourth especially clear. This is not a different paradigm: one lexeme can retain related senses whose preferred objects and scenes differ.
A derivative can outlive or obscure its base relation
Some derivatives are so frequent that learners encounter them before any related lower-grade form. Kawo is the ordinary verb “bring”; describing every token as a freshly formed ventive counterpart of a base is synchronically unhelpful. Grade 7 faru means “happen,” not simply “be begun,” despite its historical and morphological relationship with fara. Grade 4 binne “bury” is likewise an established verb, not an instruction to calculate “total burial” from an independently active basic partner.
Ta kawo mana magani daga asibiti.
She brought us medicine from the hospital. (ordinary lexical kawo)
An shirya a fara taron da ƙarfe tara, amma bai faru ba sai bayan dogon jinkiri.
The meeting was scheduled to begin at nine, but it did not take place until after a long delay. (fara versus lexicalized faru)
Calling such verbs lexicalized does not mean their morphology has vanished. Kawo still behaves like Grade 6, and faru is still intransitive like Grade 7. The label means that morphology alone does not yield the whole modern meaning.
Valency can be the most lexical part
Grade 7 consistently lacks a direct object, but individual verbs select different complements. Gamu requires da for the person or thing encountered; rabu uses da for what someone parts from; faru normally has the event as subject. English transfer is dangerous because English meet someone has a direct object.
Na gamu da ita a wajen taron, ba a ofis ba.
I met her at the conference venue, not at the office.
Kamfanonin biyu sun rabu da tsohuwar yarjejeniyar.
The two companies abandoned the old agreement.
No object-conditioned final vowel can tell you to choose da. The complement must be stored with the lexeme: gamu da, rabu da, but simply faru.
Grade 5 supplies a parallel warning. Its causative association is strong, but frequent forms such as sanar da “inform” and koyar da “teach” have conventional translations and frames. The particle da is part of the ordinary object construction; it is not optional just because English uses a bare object.
Hukumar ta sanar da ma’aikata sabon tsarin da safe.
The authority informed the employees of the new arrangement in the morning.
Malamai suna koyar da Hausa ga ɗaliban musanya.
The teachers teach Hausa to exchange students.
Lexicalization does not freeze TAM or verbal nouns
The final vowel belongs to the lexical grade, not to tense. Jawo occurs after completive, future, and subjunctive markers. In a continuative construction with no local object, its weak verbal noun is jawowa; before a local object, the weak -wa is absent.
Wannan matakin zai jawo ƙarin kuɗi a shekara mai zuwa.
This measure will cause additional expense next year.
Hayaniyar tana jawowa tun safe.
The noise has been causing trouble since morning. (effect understood; weak verbal noun jawowa)
Hayaniyar tana jawo mana matsala tun safe.
The noise has been causing us a problem since morning. (local indirect and direct objects; no weak -wa)
The verbal noun can also develop conventional nominal meanings, but do not assume that every noun resembling an extended verb is synchronically assembled in the same way. Historical relationship, present morphology, and current lexical meaning answer different questions.
How to test an unfamiliar extension
First identify the attested form, including tone and length from a marked source. Then check its subject and complements in several real sentences. Finally compare its meaning with the proposed base. If the connection is transparent, it may support productive analysis; if the frame or meaning is unexpected, preserve that lexical information rather than forcing a literal derivation.
This method also prevents a common analytical mistake: finding -o, -u, or -e and declaring a source verb without evidence. Shared consonants and a familiar ending can suggest a relationship, but accidental similarity and historical opacity exist.
Practice
Classify these as transparent, metaphorically extended, or strongly lexicalized: shanye ruwa “drink up water”; jawo kujera “pull over a chair”; jawo matsala “cause a problem”; tuno da suna “recall a name”; faru “happen”; gamu da mutum “meet someone.” Then write the lexical frame, not just the gloss: gamu da, rabu da, sanar da, koyar da.
Common Mistakes
1. Translating the extension label instead of the lexical verb.
❌ Jinkirin ya jawo matsala = jinkirin ya ja matsalar zuwa nan a zahiri.
Incorrect analysis—jawo matsala conventionally means ‘cause a problem,’ not necessarily physically pull it here.
✅ Rashin sadarwa ya jawo ruɗani a taron.
The lack of communication caused confusion at the meeting.
2. Giving gamu a direct object because English does.
❌ Na gamu shi a tashar jirgin ƙasa.
Incorrect—lexicalized Grade 7 gamu selects da.
✅ Na gamu da shi a tashar jirgin ƙasa.
I met him at the railway station.
3. Treating a final vowel as a tense ending.
❌ Jawo na nufin abin da ya riga ya faru ne kawai.
Incorrect claim—Grade 6 -o is not a past-tense suffix.
✅ Matakin zai jawo muhawara idan aka sanar da shi gobe.
The measure will provoke debate if it is announced tomorrow.
4. Inventing an extension because its meaning seems plausible.
❌ Za a iya ƙara o ga kowane fi’ili a sami kalmar Hausa tabbatacciya.
Incorrect—semantic plausibility does not prove that an imagined Grade 6 form is established.
✅ Sun samo ɗaki kusa da kasuwa bayan dogon nema.
They managed to find a room near the market after a long search. (established samo)
Key Takeaways
- Grade semantics organize the lexicon, but conventional meanings and complement frames remain word-specific.
- Lexicalized forms retain real grade morphology: jawo stays Grade 6 and gamu stays intransitive Grade 7.
- Learn prepositions and particles with the verb: gamu da, rabu da, sanar da, koyar da.
- A lexicalized final vowel is not selected by TAM.
- Historical relatedness and productive modern derivation are separate claims; verify both instead of inferring either from spelling alone.
