Cleft Sentences and Emphasis in Yoruba

In Brief

To give one part of a Yoruba sentence special emphasis, place that element first, add ni, and follow it with a clause: Adé ni ó wá means “It is Ade who came.” The element before ni is the focus—the person, thing, place, or time presented as the important or contrasting information.

Overview

A cleft sentence divides a message into two parts so that one part stands out. English often does this with “It is/was … who/that …”: “It was tomorrow that they chose.” Yoruba does not need an empty English-style “it.” Instead, the focused expression comes first, ni marks it as the focus, and the rest of the message follows.

Compare the neutral statement Adé wá (“Ade came”) with Adé ni ó wá (“It is Ade who came”). The first sentence simply reports an event. The second identifies or contrasts Ade: perhaps someone asked who came, or perhaps the speaker is correcting the claim that Bọ́lá came.

This B2 pattern builds on general Yoruba focus constructions. It matters in answers, corrections, contrasts, storytelling, and ordinary conversation. English speakers usually understand the meaning quickly, but they may copy English word order, insert an unnecessary equivalent of “it,” or leave the focused element in its normal position as well as putting it before ni.

How It Works

The basic frame

The most useful pattern is:

focused element + ni + clause

A clause is a group of words containing a predicate—that is, the part that says what happens or what is true. In the examples below, brackets show the focused element:

• [Adé] ni ó wá. — It is Ade who came.
• [Owó] ni ó nílò. — It is money that he or she needs.
• [Ọ̀la] ni wọ́n máa ṣe é. — It is tomorrow that they will do it.

The translation “It is/was …” is a natural English way to express the contrast. It does not mean that Yoruba contains a separate word corresponding to the introductory English “it.” Time is normally understood from the verb phrase and context rather than from a change in ni.

Focusing the subject

The subject is the person or thing that performs the action or is in the state described. When the subject is focused, it appears before ni, and the following clause normally still begins with a subject pronoun:

Adé ni ó wá.

Here Adé is focused, while ó is the third-person singular subject pronoun in the following clause. English does not repeat the reference in “It is Ade who came,” so this Yoruba structure needs deliberate practice.

The pronoun agrees with the focused subject:

Yoruba	English	Note
Èmi ni mo ṣe é.	I am the one who did it.	mo refers back to Èmi
Ìwọ ni o pè mí.	You are the one who called me.	o refers back to Ìwọ
Adé ni ó wá.	It is Ade who came.	ó refers back to Ade
Àwọn ọmọ ni wọ́n ń kọrin.	It is the children who are singing.	wọ́n refers back to the children

The independent pronouns èmi (“I”) and ìwọ (“you”) are suitable as focused forms. The shorter forms mo and o belong inside the following clause.

Focusing an object

An object is the person or thing affected by the action. In a neutral sentence, it usually follows the verb:

• Mo ra ìwé. — I bought a book.

To focus the object, move it before ni:

• Ìwé ni mo ra. — It is a book that I bought.

Do not repeat the same object after the verb. The missing object position in the second clause is understood from the focused expression. This is one of the clearest differences between subject focus and object focus: subject focus retains a subject pronoun in the clause, while a focused object normally leaves an understood gap after the verb.

This also applies when the English translation uses “what” or “the thing that”:

• Ohun tí mo fẹ́ ni ìwé náà. and other identification structures belong to a broader system of focus and relative clauses. For the core cleft pattern here, learn Ìwé ni mo fẹ́: “It is the book that I want.”

Focusing a place, destination, or time

A location, destination, or time expression can occupy the focus position. The clause then gives the event associated with it:

• Ilé ni mo ń lọ. — It is home that I am going.
• Ọ̀la ni wọ́n máa ṣe é. — It is tomorrow that they will do it.
• Lánàá ni ó ti ṣẹlẹ̀. — It was yesterday that it happened.

Natural English may prefer “I’m going home,” “They’ll do it tomorrow,” or “It happened yesterday,” with vocal stress on the important word. The fuller cleft translations show the Yoruba information structure more clearly.

Focus is not merely stronger pronunciation

English can often emphasise a word only by stressing it: “ADE came,” or “I bought the BOOK.” Yoruba may also use intonation in discourse, but the X ni clause construction marks the focus grammatically. The word order and ni matter; louder pronunciation alone does not produce this cleft construction.

ni as a focus marker

In this pattern, ni follows the complete focused expression. That expression may be one word or a longer noun phrase (a noun and its modifiers):

• Adé ni … — It is Ade …
• Ìwé tuntun náà ni … — It is that new book …
• Ọ̀la ni … — It is tomorrow …

Yoruba ni also appears in identifying sentences, such as expressions equivalent to “X is Y.” The uses are related, but analyse the present construction by looking for a fronted element followed by a clause containing an event or state. In Adé ni ó wá, the clause ó wá makes the focus structure visible.

Examples in Context

The English translations below are intentionally natural. Depending on context, an English speaker might use an “it-cleft,” vocal stress, or a short identifying answer.

Yoruba	English	Note
Adé ni ó wá.	It is Ade who came.	Person as focused subject
Èmi ni mo ṣe é.	I am the one who did it.	Focused first-person subject
Àwọn ọmọ ni wọ́n ń kọrin.	It is the children who are singing.	Focused plural subject
Ìwé ni mo ra.	It is a book that I bought.	Focused object
Owó ni ó nílò.	It is money that he or she needs.	Focused object; ó is the subject
Oúnjẹ ni a ń ṣe.	It is food that we are preparing.	Focused object with an ongoing action
Ilé ni mo ń lọ.	It is home that I am going.	Focused destination
Ọjà ni wọ́n lọ.	It is the market that they went to.	Focused destination
Ọ̀la ni wọ́n máa ṣe é.	It is tomorrow that they will do it.	Focused future time
Lánàá ni ó ti ṣẹlẹ̀.	It was yesterday that it happened.	Focused past time
Ní òwúrọ̀ ni a máa pàdé.	It is in the morning that we will meet.	Focused time phrase
Ìwé tuntun náà ni mo fẹ́.	It is that new book that I want.	A whole noun phrase is focused

These sentences are naturally contrastive. Owó ni ó nílò may correct the idea that the person needs advice; Ọ̀la ni wọ́n máa ṣe é may correct someone who expected the action today.

Common Mistakes

Copying the English “it” into Yoruba

• Wrong: Ó jẹ́ Adé ni ó wá.
• Right: Adé ni ó wá.
• Why: The ordinary Yoruba cleft starts directly with the focused element. Do not build it word for word from “It is Ade who came.”

Omitting the subject pronoun after a focused subject

• Wrong: Adé ni wá.
• Right: Adé ni ó wá.
• Why: With subject focus, the clause normally contains the corresponding subject pronoun, here ó.

Repeating a focused object

• Wrong: Ìwé ni mo ra ìwé.
• Right: Ìwé ni mo ra.
• Why: Ìwé has moved into the focus position. Its ordinary object position after ra is left unspoken.

Putting ni before the focused expression

• Wrong: Ni Ọ̀la wọ́n máa ṣe é.
• Right: Ọ̀la ni wọ́n máa ṣe é.
• Why: In this construction, ni follows the expression receiving focus.

Treating every fronted word as neutral word order

• Misleading: “Ìwé ni mo ra simply means the same thing in the same way as Mo ra ìwé.”
• Better: Mo ra ìwé reports “I bought a book”; Ìwé ni mo ra presents the book as the answer, correction, or contrast.
• Why: The event may be the same, but the listener is guided toward different information.

Dropping tone marks while learning

• Hard to read: Ola ni won maa se e.
• Clear: Ọ̀la ni wọ́n máa ṣe é.
• Why: Yoruba tone marks and underdots distinguish words and pronunciation. Informal digital writing may omit them, but learners should practise the fully marked forms.

Usage Notes

Clefts are common when answering an implicit or explicit question. If the question is “Who came?”, Adé ni ó wá identifies Ade. If the issue is when something will happen, Ọ̀la ni wọ́n máa ṣe é identifies tomorrow. The construction therefore does more than add emotion: it organises information structure, meaning the way a speaker separates what is already under discussion from what is presented as the key answer.

Use a cleft when there is a reason to select, correct, or contrast. If no contrast is intended, a neutral sentence is often more natural. Saying Mo ra ìwé merely reports a purchase; Ìwé ni mo ra sounds appropriate when the identity of the purchased item matters.

English translations can make Yoruba clefts look unusually formal because repeated English “It is … that …” structures may sound heavy. Do not assume the Yoruba construction has exactly the same stylistic weight. Depending on the conversation, English may render it with stress—“I bought the BOOK”—or as a brief answer, “A book.”

The spelling ni stays after the focus, while the pronouns and aspect markers in the following clause still do their normal jobs. Thus ń marks an ongoing action in Ilé ni mo ń lọ, and máa contributes future or expected meaning in Ọ̀la ni wọ́n máa ṣe é. Focus does not replace tense, aspect, or subject marking inside the clause.

Beyond the Basics / Advanced Use

Clefts and focus questions

Yoruba focus questions use the same broader focus system. Kí ni o ṣe? means “What did you do?” The question word kí occupies the position whose value is being requested, and ni marks that focus. An answer can mirror the structure:

• Kí ni o rà? — What did you buy?
• Ìwé ni mo ra. — It was a book that I bought.

This question–answer pairing is an effective way to hear why the fronted element matters: the answer supplies exactly the missing focused information.

Focused subjects and focused objects behave differently

The contrast between Adé ni ó wá and Ìwé ni mo ra is structural, not accidental. In the first, the focused person is interpreted as the subject of wá, and ó resumes that subject inside the clause. In the second, mo is already the subject; the focused book is understood as the object of ra, so it is not repeated.

Yoruba	English	What happens in the clause
Adé ni ó wá.	It is Ade who came.	A subject pronoun refers back to Ade
Ìwé ni mo ra.	It is a book that I bought.	mo is “I”; the object position is understood
Àwọn ọmọ ni wọ́n ń kọrin.	It is the children who are singing.	wọ́n refers back to the children
Owó ni ó nílò.	It is money that he or she needs.	ó means “he/she”; money is the understood object

This distinction prevents a frequent reading error: in Owó ni ó nílò, ó does not refer to the money. It is the person who needs the focused money.

Longer focused expressions

The whole phrase before ni, not just its first noun, receives focus. In Ìwé tuntun náà ni mo fẹ́, the choice is “that new book.” Keeping modifiers such as tuntun (“new”) and náà (“that/the particular one”) together lets the speaker identify a precise alternative.

Clefting can also create a chain of contrasts in careful speech or writing: one sentence can establish who acted, another what they acted on, and another when. That is rhetorically powerful, but repeated clefts can sound insistent. Use them where the contrast genuinely helps the listener.

Negating an identification

To reject a proposed identification, Yoruba commonly uses a broader negative identifying pattern with kì í ṣe (“it is not”). Its exact continuation depends on the sentence and discourse. At this level, the safest productive strategy is to master affirmative X ni clause clefts and recognise kì í ṣe X as a way of denying X before learning more elaborate negative focus patterns from complete examples.

Practice Tips

1. Build neutral–focus pairs. Start with five simple sentences such as Mo ra ìwé. Ask what you want to contrast, then produce Ìwé ni mo ra. Say both aloud and explain the difference in one English sentence.
2. Practise question–answer matching. Use Kí ni o rà? — Ìwé ni mo ra. Then replace the object, person, place, and time. This makes focus a meaningful answer rather than an abstract word-order exercise.
3. Track the clause subject. Underline the element before ni, then circle mo, o, ó, a, ẹ, or wọ́n in the clause. Ask whether it refers back to a focused subject or is a different subject acting on a focused object.
4. Keep the diacritics. Copy fully marked examples and read them with audio from a trusted Yoruba source or speaker. Focus grammar is easier to recognise when pronouns and words are not blurred by missing tones and underdots.
