A Hausa verb grade is a lexical morphophonological pattern: it associates a verb with a final termination, a tone melody, typical valency, object-conditioned forms, and often a broad meaning tendency. It is not a tense conjugation. Saya, sayi, and saye can all mean “buy” in the same completive time frame; their shape changes because of what follows the verb. The Grade 2 object page gives the core learner paradigm.
All unlabelled examples are neutral Nigerian Standard Hausa. Ordinary boko writes ɓ, ɗ, ƙ, ’y but not lexical tone or vowel length. Abstract H (high) and L (low) in technical tables describe spoken patterns; ordinary target examples remain unmarked.
One grade is a package of properties
Traditional Hausa grammar uses numbered grades, developed from Parsons’s classification and refined in later work. A grade can involve five linked facts:
- Termination: a final vowel such as -a, -e, -o, -u, or material such as Grade 5 -ar.
- Tone melody: a conventional high/low pattern over the verb.
- Valency: whether a verb is commonly transitive, intransitive, or changes the number and type of participants.
- Object environment: whether no object, a direct-object pronoun, a noun direct object, or an indirect object immediately follows.
- Lexical meaning: both a grade-wide tendency and the particular meaning established for that verb.
| Grade | Technical termination/tone sketch | Common tendency | Ordinary example |
|---|---|---|---|
| 1 | -a; H-L-(H) | often transitive; basic or derived | karanta “read” |
| 2 | A -a, B -e, C -i; mainly L-H patterns | variable-vowel transitive verbs | saya / saye / sayi “buy” |
| 3 | -a or other subpatterns; commonly L-H | mostly intransitive | varied lexical class |
| 4 | -e; H-L-(H) | transitive or intransitive; often total/resultative tendency | rufe “close” |
| 5 | -ar and related causative frames | causative/efferential tendency | sayar “sell” |
| 6 | -o; all H | ventive/allative or action oriented toward a deictic center | sayo “buy and bring” |
| 7 | -u; L-H | intransitive result or affected subject | sayu “be bought / sell” |
The labels are descriptive, not commands that generate every imaginable form. Some verbs are basic members of a grade; other grade forms are derived from a related base. Many roots do not have an ordinary, attested member in every grade.
Grade 2 makes the system visible in boko
The variable-vowel Grade 2 verb saya “buy” shows why the following environment matters. In a widely used technical convention, A means no following object, B a direct-object pronoun, C another direct object such as a noun phrase, and D an indirect object. Because letter conventions can differ across teaching traditions, the syntactic names matter more than the letters.
| Environment | Form | Example |
|---|---|---|
| No following object (A) | saya | Na saya. |
| Direct-object pronoun (B) | saye | Na saye shi. |
| Noun direct object (C) | sayi | Na sayi littafi. |
| Indirect object (D) | saya; verb-specific D-pattern | Na saya masa littafi. |
Na saya a kasuwa jiya.
I bought some at the market yesterday. (no following object)
Na sayi littafi a kasuwa jiya.
I bought a book at the market yesterday. (noun direct object)
Mun saye ta daga shagon kusa da gida.
We bought it from the shop near home. (feminine direct-object pronoun)
Na saya masa littafi a kasuwa jiya.
I bought him a book at the market yesterday. (indirect object immediately after the verb)
The completive marker na is identical in all four examples. The final vowel does not mark tense; it responds to the verb’s grade and syntactic environment.
Regular grades can hide the contrast in writing
Grade 1 karanta “read” and Grade 4 rufe “close” also have environment-sensitive tone and final-vowel length, but ordinary boko usually writes the same letters.
Na karanta kafin na kwanta.
I read before going to bed. (nothing follows the verb)
Na karanta rahoton kafin taro.
I read the report before the meeting. (noun object)
Na karanta shi sau biyu.
I read it twice. (direct-object pronoun)
Amina ta rufe shagon da wuri.
Amina closed the shop early.
Amina ta rufe shi da wuri.
Amina closed it early.
The spelling does not show every spoken distinction. A grade is therefore not merely “which final letter do I see?” Tone, length, syntax, and lexical behavior belong to the classification too.
A grade is not a productive tense conjugation
English changes buy to bought for past tense. Hausa normally changes the preverbal subject–TAM complex while retaining the appropriate grade form:
Na sayi kayan jiya.
I bought the goods yesterday.
Zan sayi kayan gobe.
I will buy the goods tomorrow.
Ina sayen kayan yanzu.
I am buying the goods now.
The noun-object form sayi appears in completive and future. The continuative uses a verbal-noun construction, sayen kayan, rather than selecting a “present-tense grade.” TAM choice and grade morphology interact, but they answer different grammatical questions.
A root can operate in more than one grade
A lexical family may have several grade members, each with a conventional meaning. With the say- family:
| Form | Grade | Established meaning tendency |
|---|---|---|
| saya / sayi / saye | 2 | buy |
| saye | 4 | buy up / buy completely |
| sayar | 5 | sell |
| sayo | 6 | buy and bring toward the relevant center |
| sayu | 7 | be bought; sell successfully |
Sun saye kayan duka kafin rana ta faɗi.
They bought up all the goods before sunset. (Grade 4 totality reading)
Mai shagon ya sayar da tsohuwar firij.
The shopkeeper sold the old refrigerator. (Grade 5 lexicalized causative/efferential form)
Don Allah ka sayo mana ruwa a hanyarka.
Please buy and bring us water on your way. (Grade 6 ventive form)
Kayan sun sayu da sauri.
The goods sold quickly. (Grade 7 affected/result reading)
The tendencies help memory, but there is no guarantee that every root forms every grade or that its meaning is perfectly compositional. Sayar is the ordinary lexical verb “sell”; learners should store that meaning, not calculate it anew each time.
Grade, extension, and verbal noun
Derived grades are sometimes called verbal extensions because they alter the base’s direction, valency, result structure, or participant roles. The continuative then normally uses a verbal noun associated with the selected verb: yana sayen kaya “he is buying goods,” yana sayar da kaya “he is selling goods.”
Verbal-noun shape is related to the verb’s morphology but is not always fully predictable. Dictionaries and attested usage remain essential. The grade system predicts many patterns; it does not replace lexical learning.
Practice: separate the two choices
For each example, identify (a) its TAM frame and (b) why the verb has that form.
Za mu sayi sabuwar mota shekara mai zuwa.
We will buy a new car next year. (future TAM; Grade 2 before a noun object)
Mun saye ta bayan mun gwada ta.
We bought it after testing it. (completive TAM; Grade 2 before a direct-object pronoun)
Muna sayen kayan daga Kano.
We buy / are buying the goods from Kano. (continuative TAM; verbal noun before a noun object)
Common Mistakes
1. Selecting a Grade 2 vowel by tense.
❌ Zan saya littafi gobe.
Incorrect in the intended noun-object frame — future tense does not license the no-following-object form.
✅ Zan sayi littafi gobe.
I will buy a book tomorrow.
2. Treating the citation form as invariant.
❌ Na saya shi jiya.
Incorrect standard Grade 2 form before a direct-object pronoun.
✅ Na saye shi jiya.
I bought it yesterday.
3. Generalizing Grade 2 alternation to Grade 1.
❌ Na karante shi sau biyu.
Incorrect — karanta is not made into an invented -e pronoun form.
✅ Na karanta shi sau biyu.
I read it twice.
4. Assuming every grade contributes one automatic meaning.
❌ Duk wani fi’ili zai zama na aji na shida idan an ƙara masa o.
Incorrect claim — adding o mechanically does not guarantee an attested Grade 6 verb or meaning.
✅ Za ka iya sayo mana madara daga shagon?
Can you buy and bring us milk from the shop? (attested sayo; addressing one male)
5. Using a direct-object form before an indirect object.
❌ Mun saye musu kayan aiki kafin taron.
Incorrect standard Grade 2 frame — musu is an indirect object.
✅ Mun saya musu kayan aiki kafin taron.
We bought them equipment before the meeting.
Key Takeaways
- A grade links termination, tone melody, valency, object-conditioned form, and lexical meaning.
- Grades are not tenses; subject–TAM marking carries most tense, aspect, mood, person, and polarity information.
- Grade 2 visibly uses -a with no following object, -e before a direct-object pronoun, and -i before a noun object.
- Grade 1 and Grade 4 environment differences may be audible but invisible in ordinary boko.
- Derived grade meanings are tendencies constrained by the lexicon, not automatic rules applying freely to every root.
- Learn each verb with its attested grade, frames, derived relatives, and verbal noun.
