Grade 4 has a strong regular core—H–L(–H) tone, final -e, and a short low C-form before a noun direct object—but its lexical families are not built by one mechanical “change the last vowel to e” rule. Some stems palatalize before -e, monosyllabic bases use -nye, many common Grade 4 verbs have no everyday lower-grade base, and some derived meanings have become independent lexical entries. These facts are manageable once “irregular” is separated into phonological alternation, morphological allomorphy, and lexical unpredictability. The same conservation principle is developed in lexical exceptions to grade predictions.
All unlabelled examples are (neutral Nigerian Standard Hausa). Tone and length appear only as abstract H/L descriptions. Normal examples use ordinary boko.
What remains regular
Before studying exceptions, keep the dependable object paradigm in view. Ajiye “put away, set down, deposit” is a basic Grade 4 verb: its modern meaning does not require learners to derive it from another everyday verb.
| Environment | Example | Grade 4 behavior |
|---|---|---|
| no following object | Amina ta ajiye. | long final -e; ordinary H–L–H melody |
| noun direct object | Amina ta ajiye littafin. | short final -e; final low tone |
| direct-object pronoun | Amina ta ajiye shi. | long base form before the pronoun |
| indirect object | Amina ta ajiye mini littafin. | long D-form before mini |
Amina ta ajiye, amma ban ga inda ta sa kayan ba.
Amina put them away, but I did not see where she put the things. (object understood)
Amina ta ajiye littafin a saman tebur.
Amina put the book on top of the table. (noun direct object)
Amina ta ajiye shi a wurin da yara ba za su kai ba.
Amina put it where the children cannot reach it. (direct-object pronoun)
Amina ta ajiye mini littafin a ofis.
Amina left the book for me at the office. (beneficiary immediately after the verb)
The same spelling does not mean that final -e has the same length and tone in all four sentences. Grade 4 irregularities sit on top of this regular object-conditioned system; they do not erase it.
Palatalization can hide the relation to the base
The front vowel -e historically and synchronically conditions familiar coronal alternations. In derived Grade 4 families, stem-final t commonly appears as c, d or z as j, and s as sh before the extension. The learner therefore cannot always recover a Grade 4 member by merely replacing a written final vowel.
The clearest everyday pair is ɓata “get lost, become spoiled” and Grade 4 ɓace “be completely lost, disappear.” Another is gudu “run away” and Grade 4 guje “avoid, run away from.” Their semantic relation is real, but it is not a simple tense alternation.
Makullin ya ɓata a cikin gida.
The key got lost inside the house. (intransitive base)
Makullin ya ɓace gaba ɗaya; har yanzu ba mu same shi ba.
The key disappeared completely; we still have not found it. (Grade 4 result/totality)
Yaron ya gudu lokacin da ya ji ƙarar.
The boy ran away when he heard the noise. (basic intransitive verb)
Direbobi suna guje wa wannan hanyar da dare.
Drivers avoid this road at night. (Grade 4 separative verb with wa complement)
Notice that guje wa has a lexically selected complement. A learner who sees English avoid this road may try to make hanyar an unmarked direct object, but the established Hausa frame contains wa. Grade membership predicts phonology; the individual verb determines its complement structure.
These alternations are regular sound relationships where they apply, but the existence and meaning of a derived verb remain lexical. Not every stem ending in t, d, z, or s has a current Grade 4 partner.
Monosyllabic bases use -nye
Grade 4 relatives of several monosyllabic verbs use -nye, not a bare -e attached visibly to the one-syllable form. Central examples are ci → cinye “eat → eat up,” sha → shanye “drink → drink up,” and ja → janye “pull → pull away, withdraw.” Their H–L–H Grade 4 shape and -e ending are regular at the level of the resulting verb, while -nye is the allomorph required by this small stem type.
Yaran sun ci abinci kafin su tafi makaranta.
The children ate food before they went to school. (basic ci)
Yaran sun cinye abincin da aka ajiye musu.
The children ate up the food that had been set aside for them. (Grade 4 cinye)
Ta sha rabin ruwan kawai.
She drank only half of the water. (basic sha)
Ta shanye ruwan duka saboda tana jin ƙishirwa.
She drank up all the water because she was thirsty. (Grade 4 shanye)
Ma’aikatan sun janye tsohuwar motar daga hanya.
The workers pulled the old vehicle away from the road. (Grade 4 janye)
Do not analyze the n and y as separate pronouns or TAM markers. They belong to the Grade 4 stem. The corresponding weak verbal nouns are regular cinyewa, shanyewa, janyewa in contexts that select the -wa formation.
Yana shanyewa a hankali saboda ruwan yana da zafi.
He is drinking it up slowly because the water is hot. (no following object; weak verbal noun)
Suna janye motocin da suka lalace daga kan hanya.
They are removing broken-down vehicles from the road. (verbal noun before an overt object)
Some Grade 4 verbs are basic or deeply lexicalized
The semantic labels “totality,” “completion,” and “separation” describe important Grade 4 tendencies, not a definition. Rufe “close,” gane “understand/recognize,” gode “thank,” and ajiye “put away” are ordinary Grade 4 lexemes whose everyday uses need not feel like productive extensions. Other forms historically related to a base have lexicalized: binne “bury,” garƙe “confine,” and kauce “deviate/avoid” must be learned with their own meanings and frames.
Na gane kuskurena bayan ta yi mini bayani.
I understood my mistake after she explained it to me.
Mun gode muku da taimakon da kuka ba mu.
We thanked you for the help you gave us.
An binne tsohon shugaban a garinsu.
The former leader was buried in his hometown. (neutral/formal report)
Motar ta kauce wa ramin da ke tsakiyar hanya.
The vehicle swerved around the pothole in the middle of the road.
Gode selects the recipient pattern gode wa mutum / gode masa, not a direct-object pronoun: mun gode masa, not an invented neutral mun gode shi. Kauce likewise normally takes wa for the entity avoided. These lexical frames are just as important as the final vowel.
The high-frequency verb ce sits at the edge of the pattern
The monosyllabic verb ce “say” has a falling-tone long vowel in careful pronunciation and patterns in several respects with regular high-tone verbs, but it is not a productive example of attaching Grade 4 -e to a visible base. Its verbal noun is cewa, and its complement can be a quotation or clause.
Musa ya ce zai dawo da yamma.
Musa said that he would return in the evening.
Tana cewa ba ta ga saƙon ba.
She is saying that she did not see the message.
With a recipient, use the established dative frame, for example ce masa “say to him/tell him,” rather than trying to create a regular noun-object C-form.
Na ce masa ya jira ni a ƙofar ofis.
I told him to wait for me at the office door.
This is an honest irregular corner: some descriptions call ce an irregular Grade 4 verb, while learner grammars group it with exceptional monosyllabic verbs. Either analysis yields the same practical instruction—memorize ce, cewa, ce masa, and its clause frames as established forms.
Variation does not license random forms
Descriptions of Standard Hausa record a variant in which some speakers retain long -e even before a noun object, where the baseline paradigm has short low -e. That is a genuine spoken variant, but boko does not reveal the contrast. Learners should acquire the locally dominant pronunciation from reliable speakers and keep the regular short C-form as the neutral pedagogical baseline.
Similarly, a speaker may know a lexicalized or regional Grade 4 form absent from another speaker’s everyday vocabulary. Label such forms (regional: specified area) only when the region is known; do not use “dialectal” as a way to excuse an unattested derivation.
Practice
Classify the special fact in each item. Cinye uses the monosyllabic -nye allomorph; ɓata → ɓace includes a coronal alternation before -e; gode masa has a lexical dative frame; ajiye is a basic Grade 4 lexeme; cewa is the verbal noun of exceptional ce. Then put ajiye into the four frames shown at the start: ta ajiye; ta ajiye littafin; ta ajiye shi; ta ajiye mini littafin.
Common Mistakes
1. Building Grade 4 by changing every final vowel to e.
❌ Duk fi’ilin da aka canja ƙarshensa zuwa e yana zama Grade 4.
Incorrect claim — attested derivation, stem shape, and lexical meaning all matter.
✅ Ci yana da tabbatacciyar sigar Grade 4 cinye.
Ci has the established Grade 4 form cinye.
2. Missing the stem alternation in an established family.
❌ Makullin ya ɓate gaba ɗaya.
Incorrect invented form for the intended Grade 4 meaning.
✅ Makullin ya ɓace gaba ɗaya.
The key disappeared completely.
3. Giving every Grade 4 verb a direct object.
❌ Mun gode shi bayan taron.
Incorrect — gode selects a dative recipient, not a neutral direct-object pronoun.
✅ Mun gode masa bayan taron.
We thanked him after the meeting.
4. Treating totality as the meaning of every member.
❌ Ajiye koyaushe yana nufin ‘ajiye kome gaba ɗaya.’
Incorrect claim — ajiye is the lexical verb ‘put away/set down,’ without obligatory totality.
✅ Ta ajiye takarda ɗaya a kan tebur.
She put one sheet of paper on the table.
5. Predicting the verbal noun from English.
❌ Tana ce da ba za ta zo ba.
Incorrect continuative formation for ce ‘say.’
✅ Tana cewa ba za ta zo ba.
She says that she will not come.
Key Takeaways
- The regular Grade 4 frame remains long -e in A/B/D and short low -e before a noun direct object.
- Stem alternations such as ɓata → ɓace accompany some derived members; they are not tense changes.
- Monosyllabic bases can use -nye: cinye, shanye, janye.
- Many common Grade 4 verbs are basic or lexicalized, and their complement frames must be learned individually.
- Exceptional ce has verbal noun cewa and should be memorized with its clause and recipient frames.
