Yoruba verbs are remarkably straightforward in form. A Yoruba verb does not change its shape for person, number, tense, or aspect. The verb jẹ (to eat) is jẹ whether the subject is I, you, he, we, or they, and whether the action happened yesterday, is happening now, or will happen tomorrow. This is a profound contrast with English, where verbs change form for tense (eat, ate, eaten), number (eats, eat), and person (am, is, are). The simplicity of Yoruba verb morphology is a gift to learners who have struggled with conjugation in European languages.
What Yoruba does use is a set of pre-verbal aspect and tense markers. These small words come between the subject pronoun and the verb, telling the listener whether the action is ongoing, completed, habitual, or future. Combined with serial verb constructions, a hallmark feature of Yoruba grammar, these markers allow speakers to express a rich array of meanings without ever modifying the verb itself.
This reference covers the principal tense and aspect markers: ń for continuous, ti for perfect and perfective, máa and yóò for future, kì í for habitual negation, and others. It also introduces serial verb constructions, negation, and the overall structure of the Yoruba verb phrase. By the end of this chapter, learners should be able to understand and construct Yoruba sentences in all major tense-aspect configurations.
The Bare Verb: Simple Completed Action
A Yoruba verb with no aspect marker in front of it typically refers to a completed past action or to a general truth. This is the unmarked baseline from which all other aspect-marked forms depart.
| Yoruba | Translation |
|---|---|
| Mo jẹun. | I ate. |
| Ó lọ. | He/she went. |
| Wọ́n wá. | They came. |
| A ra ọjà. | We bought goods. |
| Ẹ ṣe é. | You all did it. |
The bare verb can also express a present statement of general fact or habitual truth in certain contexts: Ó mọ̀ (He/she knows) without continuous marking expresses a current state, not "he/she is knowing." Verbs of mental state and sensory perception behave this way, parallel to English "stative" verbs which resist progressive forms.
The Continuous Marker ń
The syllabic nasal ń, pronounced as a high-tone n that forms its own syllable, marks ongoing action. It is placed between the subject and the verb.
| Yoruba | Translation |
|---|---|
| Mo ń jẹun. | I am eating. |
| Ó ń kọrin. | He/she is singing. |
| A ń kọ́ èdè Yorùbá. | We are learning Yoruba. |
| Wọ́n ń ṣiṣẹ́. | They are working. |
| Ẹ ń kà ìwé. | You all are reading a book. |
The particle ń is pronounced with a full high tone. It is not silent and should not be elided even in rapid speech. In informal text it is sometimes written as n without the tone mark, but this is non-standard.
Past Continuous with ti and ń
To express an action that was ongoing in the past ("I was eating"), combine the past marker ti with the continuous marker ń in a specific order.
| Yoruba | Translation |
|---|---|
| Mo ti ń jẹun nígbà tí ó dé. | I was eating when he arrived. |
| Ọmọ náà ti ń sọkún. | The child had been crying. |
| Wọ́n ti ń ṣiṣẹ́ láti àárọ̀. | They had been working since morning. |
The combination ti ń is common and expresses "was V-ing" or "had been V-ing" in context.
The Perfect Marker ti
The marker ti placed before the verb indicates that the action is complete relative to a reference point. It is often translated as English "have V-ed" or "had V-ed" depending on context.
| Yoruba | Translation |
|---|---|
| Mo ti jẹun. | I have eaten. |
| Ó ti lọ. | He/she has gone. |
| Wọ́n ti parí iṣẹ́. | They have finished the work. |
| A ti ra ilé tuntun. | We have bought a new house. |
| Ẹ ti rí i? | Have you seen it? |
The ti marker emphasizes completion and present relevance. Mo ti jẹun indicates that the eating event is finished and is relevant now (for example, refusing an offer of food: "I have eaten already, thank you"). Contrast with bare past Mo jẹun, which simply reports a past event without the present-relevance implication.
Perfect Progressive with ti ń
As noted in the continuous section, ti ń together marks an action that was ongoing at a reference point. The past perfect progressive.
The Future Markers: máa, máa ń, and yóò
Yoruba has several ways to express future action, differing in formality, certainty, and aspect.
Simple Future with yóò
The particle yóò (sometimes contracted to 'óò) marks simple future, predicting an action that will happen.
| Yoruba | Translation |
|---|---|
| Mo yóò lọ ní ọ̀la. | I will go tomorrow. |
| Ó yóò wá. | He/she will come. |
| Wọ́n yóò jẹun. | They will eat. |
| A yóò rí i. | We will see it. |
Yóò is more formal and is used in written and careful spoken registers.
Intentional Future with máa
The particle máa marks intentional or immediate future. It often translates as "going to" or "about to."
| Yoruba | Translation |
|---|---|
| Mo máa lọ ní báyìí. | I am about to go now. |
| Ó máa jẹun lẹ́sẹ̀kẹsẹ̀. | He/she is going to eat right away. |
| Wọ́n máa ra á. | They are going to buy it. |
Habitual Future with máa ń
Combining máa with the continuous ń produces the habitual aspect, expressing regular or repeated future action.
| Yoruba | Translation |
|---|---|
| Mo máa ń jẹun ní aago mẹ́fà. | I usually eat at six o'clock. |
| Wọ́n máa ń wá ní ọjọ́ Ẹtì. | They usually come on Fridays. |
| Ẹ máa ń kọrin níbẹ̀. | You all always sing there. |
The habitual máa ń is productive and covers what English expresses with "usually," "always," "habitually," or the simple present of routine.
Negation Patterns
Negation in Yoruba uses the particle kò (not), which comes between the subject and the aspect marker (if any).
Simple Negative
| Yoruba | Translation |
|---|---|
| N kò jẹun. | I did not eat. |
| Kò lọ. | He/she did not go. |
| Wọn kò wá. | They did not come. |
| A kò rí i. | We did not see it. |
| Ẹ kò mọ̀. | You all did not know. |
Note that in the first person singular, mo often elides or changes form in the negative, commonly appearing as N or mi.
Negative Continuous
The negative of the continuous is formed with kò plans plus a changed form of the verb phrase. The particle ń is often dropped in the negative, with the sense of non-continuation expressed by other means.
| Yoruba | Translation |
|---|---|
| N kò jẹun. (Can mean I am not eating or I do not eat.) | I am not eating / I do not eat. |
| Kò ń lọ. | He/she is not going. |
Negative Habitual with kì í
The habitual negative uses the particle kì í, which expresses "never" or "does not habitually."
| Yoruba | Translation |
|---|---|
| N kì í jẹ ẹran. | I do not eat meat. (I never eat meat.) |
| Kì í mu ọtí. | He/she does not drink alcohol. |
| Wọn kì í wá níbí. | They do not come here. |
The kì í construction is strongly habitual: it marks a characteristic or rule-governed negation, not a one-time failure to do something.
Negative Perfect
The perfect is negated with kò plus tí (a different particle from ti).
| Yoruba | Translation |
|---|---|
| N kò tí ì jẹun. | I have not eaten yet. |
| Kò tí ì dé. | He/she has not arrived yet. |
| Wọn kò tí ì parí. | They have not finished yet. |
The "yet" meaning comes from the combination kò tí ì.
Serial Verb Constructions
One of the most distinctive features of Yoruba is the serial verb construction, in which two or more verbs appear in sequence with a single subject and a single time reference, expressing what English typically encodes in a single verb or in a verb plus preposition.
| Yoruba | Literal | Idiomatic Translation |
|---|---|---|
| mú wá | take come | bring |
| gbà lọ | take go | take (away) |
| rí gbà | see accept | encounter |
| gé kúrò | cut remove | cut off |
| fi sí | put place | put into |
| ta sọfọ́ | throw lose | waste (throw away) |
Serial Verbs in Sentences
| Yoruba | Translation |
|---|---|
| Mo mú ìwé wá. | I brought a book. (I took a book and came.) |
| Ó gbé ọmọ lọ sí ilé-ìwé. | He/she took the child to school. |
| Ẹ mú omi wá fún mi. | Bring water for me. |
| Wọ́n lọ ra ọjà. | They went and bought goods. |
| A dé ilé tán. | We arrived home finally. |
Serial verb constructions are productive; new combinations can be generated freely. The key point is that each verb is a full verb contributing its meaning, but together they form a single event expression. English speakers sometimes try to translate each verb separately, producing clumsy prose; the idiomatic translation fuses them.
Why Serial Verbs Matter
Many meanings that English expresses through prepositions or particles are expressed in Yoruba through serial verbs. "To" and "at" in spatial expressions often correspond to lọ (go), "with" corresponds to pẹ̀lú (with) but also to fi (use, take) in some constructions, and "for" can be expressed with fún (give).
Learning common serial verb combinations as fixed expressions is an efficient way to expand expressive range.
Stative Versus Dynamic Verbs
Some Yoruba verbs describe states rather than actions. Stative verbs typically appear without the continuous marker ń even when expressing a currently true meaning.
| Yoruba | Translation |
|---|---|
| Ó mọ̀. | He/she knows. |
| Mo fẹ́ ọ. | I love you. |
| Ó tóbi. | It is big. |
| Ara mi dá. | I am well. (My body is sound.) |
Adding ń to a stative verb forces a dynamic reading: Ó ń mọ̀ would mean "He is coming to know" or would be ungrammatical, rather than "He knows."
Adjectival meanings in Yoruba are often expressed by verbs. Ó tóbi literally means "It bigs" or "It is big." There is no copula "be" with predicate adjectives in most cases; the adjective-like word is itself the verb.
Example Sentences Across Tense-Aspect
To see the full system in action:
| Yoruba | Translation |
|---|---|
| Mo jẹun. | I ate. |
| Mo ń jẹun. | I am eating. |
| Mo ti jẹun. | I have eaten. |
| Mo ti ń jẹun. | I was eating / I had been eating. |
| Mo máa jẹun. | I will eat (soon, intentionally). |
| Mo yóò jẹun. | I will eat. |
| Mo máa ń jẹun ní aago mẹ́fà. | I usually eat at six. |
| N kò jẹun. | I did not eat / I am not eating. |
| N kì í jẹ ẹran. | I do not eat meat (habitually). |
| N kò tí ì jẹun. | I have not eaten yet. |
A single verb jẹ yields this entire range with small particle changes.
Common Mistakes
Treating Yoruba like English for tense. English speakers expect the verb itself to signal tense. Yoruba speakers expect the particle to signal it. Forgetting the particle or putting it in the wrong position is the most common error.
Omitting the continuous marker ń. Without ń, the sentence Mo jẹun is past or habitual, not progressive. To say "I am eating right now," you must include ń.
Confusing ti and tí. The perfect marker ti has mid tone; the complementizer tí (that, which, who) has high tone. They look similar but have different functions.
Translating serial verbs word by word. Mú wá is not "take come" in English; it is "bring." Learning serial verb combinations as units is essential.
Using ń with stative verbs. Stative verbs like mọ̀ (know) and tóbi (be big) do not take ń in normal contexts. Forcing them into the continuous produces ungrammatical sentences.
Forgetting to adapt the first person in negatives. Mo jẹun becomes N kò jẹun, not Mo kò jẹun. This alternation is memorized with practice.
Wrong order with double particles. Ti ń (past continuous) has a fixed order; reversing to ń ti is ungrammatical. Practice the combinations as whole patterns.
Ignoring the distinction between máa and yóò. Both mean "will" but in different registers and with different shades of intention. Using them interchangeably without thought produces slightly awkward style.
Quick Reference
Bare verb: simple past or general truth (Mo jẹun = I ate). ń: continuous (Mo ń jẹun = I am eating). ti: perfect (Mo ti jẹun = I have eaten). ti ń: past continuous (Mo ti ń jẹun = I was eating). máa: intentional or immediate future. máa ń: habitual (Mo máa ń jẹun = I usually eat). yóò: simple or formal future. kò: basic negator. kì í: habitual negator (never). kò tí ì: not yet perfect. Serial verbs: two or more verbs together expressing one event. No conjugation for person or number. No passive voice; use third person plural instead.
FAQ
Why does Yoruba have no past tense ending on the verb?
Many languages of the world lack morphological tense on the verb. Mandarin Chinese and many languages of Southeast Asia and West Africa express time through particles, adverbs, and context rather than through verb endings. This is a different but equally effective way of encoding time.
How do I know when a bare verb means past versus present?
Context. Adverbs of time (ní àná = yesterday, lónìí = today, ní ọ̀la = tomorrow) disambiguate. Stative verbs default to present; dynamic verbs default to past when unmarked. Habitual contexts default to habitual present.
Are serial verbs the same as compound verbs?
No. A compound verb in languages like German or Hungarian combines verbal elements into a single fused form. Yoruba serial verbs remain separate words, each capable of standing alone. They simply occur together to express a single complex event.
Can any two verbs form a serial verb construction?
No. There are conventional combinations that speakers recognize and use, and novel combinations that may be grammatical but sound odd. Learning a stock of common serial verbs (like mu wá, mu lọ, gbé lọ, rí gbà) is the practical approach.
How do I express the English present perfect ("have been V-ing")?
Use ti ń: Mo ti ń kọ́ èdè Yorùbá fún ọdún méjì (I have been learning Yoruba for two years). The combination captures both the completion at a reference point and the ongoing nature.
What about modals like can, should, must?
These are expressed with auxiliary-like verbs and particles: lè (can, be able to), gbọdọ̀ (must), yẹ (should), fẹ́ (want). They appear before the main verb similarly to aspect markers. For example, Mo lè ṣe é (I can do it), Ó yẹ kí o wá (You should come).
Do Yoruba speakers distinguish simple past from present perfect as carefully as English speakers?
Not quite as often. The distinction exists in Yoruba grammar (bare verb vs. ti), but in everyday speech the perfect is used somewhat less frequently than English present perfect. Context often supplies the relevant information without requiring explicit marking.

Frequently Asked Questions
Do Yoruba verbs conjugate?
Yoruba verbs do not conjugate for person or number. The same verb form is used with every subject. Tense and aspect are marked by pre-verbal particles rather than by changing the verb's shape.
How is the present continuous formed in Yoruba?
Place the particle ń (high tone syllabic nasal) between the subject pronoun and the verb: Mo ń jẹun (I am eating). The ń is pronounced as a full syllable with high tone.
What is a serial verb construction?
A serial verb construction is a string of verbs in a row that together express a single complex event. For example mu wá (bring) literally combines mu (take) and wá (come). Serial verb constructions are a hallmark of Yoruba grammar.
How do I form the past tense in Yoruba?
Yoruba bare verbs without any marker are typically interpreted as simple past or completed action: Mo jẹun means I ate. For a perfect or resultative meaning, add ti: Mo ti jẹun (I have eaten).
What is the difference between máa and yóò?
Both mark future tense. Máa expresses a habitual or generic future and sometimes immediate intention. Yóò expresses a simple or predictive future. Yóò is more formal and literary; máa is more conversational.
How is negation formed?
The negator kò precedes the verb and follows the subject: Mo jẹun (I ate) becomes N kò jẹun (I did not eat). Different aspect markers combine with kò in specific patterns covered in this reference.
Is there a passive voice in Yoruba?
Yoruba does not have a grammaticalized passive voice like English. Passive meaning is expressed with the generic third person plural (they) or by rephrasing. The structure Wọ́n pa á means they killed him, which often translates as he was killed.
