Ipò, Ìdí, àti Ìmọ̀ràn
Chapter Objectives
By the end of this chapter, you will be able to:
- State a simple condition using bí ("if") and a simple time relationship using nígbà tí ("when").
- Give a simple reason using nítorí ("because") and torí náà ("so, therefore").
- Express obligation and necessity using gbọ́dọ̀ ("must") with independent control in familiar contexts.
- Express ability and permission using lè ("can, may") with independent control in familiar contexts.
- Give a warning or a prohibition using má, extended to safety and advice contexts.
- Write and speak a short piece of practical advice that combines a condition or reason with an obligation, ability, or prohibition.
Communication Scenario
Adé's neighbor, Ìyá Kúmọ́lá, is preparing to travel by bus to a nearby town for the first time in a while. She stops by to ask Adé's family for advice about the trip: what she must bring, what she should avoid, and what to do if something goes wrong along the way.
- Chapter 16 consolidated ni identification, subject focus, and object focus, and introduced clarification questions with ta ni, kí ni, and níbo ni.
- This chapter turns from identifying and clarifying facts toward giving advice: stating conditions, reasons, obligations, abilities, and warnings.
- Basic if/when/reason connectors are introduced here as controlled formulas. Gbọ́dọ̀ and lè move from formulaic to consolidated productive use, and prohibitions with má are developed beyond simple household commands into advice and safety contexts.
Core Vocabulary
This chapter adds vocabulary for advice, rules, safety, and obligations, and it assumes full control of the Chapter 1–16 vocabulary checkpoint, including the focus and clarification language from Chapter 16.
| Yorùbá | English | Notes |
|---|---|---|
| bí | if | conditional connector |
| nígbà tí | when | time connector, recycled from earlier chapters |
| nítorí | because | reason connector |
| torí náà | so, therefore | result connector |
| gbọ́dọ̀ | must, have to | obligation particle, now consolidated |
| lè | can, may, be able to | ability/permission particle, now consolidated |
| má | do not (prohibition) | negative-command particle, extended to advice/safety |
| ìṣọ́ra | caution, carefulness | advice and safety vocabulary |
| ìmọ̀ràn | advice | chapter theme word |
| ẹ̀rí ìdánimọ̀ | identification document | travel vocabulary |
| ọkọ̀ akérò | bus | travel vocabulary |
| ewu | danger | safety vocabulary |
All items are fully tone-marked and dot-underlined. Bí and nítorí are introduced as controlled connective formulas; full subordinate-clause analysis remains deferred to a later volume.
Pronunciation Focus
Warnings and advice in Yorùbá often rely on precise tone to distinguish urgency from ordinary statement. Two points deserve attention:
- The prohibition particle má carries a high tone and is typically spoken with a firmer, slightly slower delivery than an ordinary statement, without becoming harsh.
- Gbọ́dọ̀ and lè must keep their tone pattern steady even when spoken quickly in a string of advice; flattening their tone can blur the difference between "must" and "can."
Practice reading the Chapter 17 building-block examples aloud slowly first, then at a natural advice-giving pace, keeping tone steady throughout.
Grammar and Sentence Patterns
This chapter introduces basic if/when/reason connectors as controlled formulas, consolidates gbọ́dọ̀ and lè for independent productive use, and develops prohibitions with má into advice and safety contexts.
Conditions and time with bí and nígbà tí
Bí introduces a condition, and nígbà tí introduces a time relationship. Both connectors are used here as controlled formulas: learners state the condition or time clause, then follow directly with the result, without needing to master the full range of subordinate-clause structures yet.
- Bí o bá dé ibùdókọ̀, pe mí lẹ́sẹ̀kẹsẹ̀. If you arrive at the bus station, call me right away. bí...bá=if (conditional formula)
- Nígbà tí o bá ń múra sílẹ̀, mú ẹ̀rí ìdánimọ̀ rẹ pẹ̀lú. When you are getting ready, bring your identification with you. nígbà tí=when (time formula)
Giving reasons with nítorí and torí náà
Nítorí gives a reason for a statement that came before it. Torí náà introduces a result or a piece of advice that follows from a reason already given. Together they let learners build short, connected pieces of practical advice.
- Ẹ gbọ́dọ̀ dé ní kùtùkùtù, nítorí àwọn ọkọ̀ kì í dúró pẹ́. You must arrive early, because the buses do not wait long. nítorí=because (reason formula)
- Ọ̀nà náà le máa dí lálẹ́, torí náà, má lọ nìkan ṣoṣo lálẹ́. The road can get congested at night, so do not go alone at night. torí náà=so, therefore (result formula)
Obligation with gbọ́dọ̀ and ability/permission with lè
Gbọ́dọ̀ expresses necessity or strong obligation. Lè expresses ability or permission. Both particles are now consolidated for independent use: learners should be able to use them accurately in new, familiar-type advice situations without a model sentence to copy.
- Ẹ gbọ́dọ̀ ṣọ́ra pẹ̀lú àwọn nǹkan yín ní ọkọ̀ akérò. You must be careful with your belongings on the bus. gbọ́dọ̀=must (obligation)
- O lè jókòó ní ẹ̀gbẹ́ fèrèsé bí o bá fẹ́. You can sit by the window if you like. lè=can (ability/permission)
Warnings and prohibitions with má
Má was introduced earlier for simple household prohibitions. This chapter develops má further into advice and safety warnings, where it is used to caution someone about a real risk rather than to issue a simple household command.
- Má fi ẹrù rẹ sílẹ̀ láìsí àkíyèsí, torí ewu wà. Do not leave your luggage unattended, because there is danger. má=do not (safety prohibition)
- Má bẹ̀rù láti béèrè ìrànlọ́wọ́ bí ohunkóhun bá ṣẹlẹ̀. Do not be afraid to ask for help if anything happens. má=do not (advice, not a strict command)
Full negative-focus interaction, embedded conditional clauses, and advanced subordination remain deferred to a later volume; this chapter keeps condition, reason, obligation, ability, and prohibition at the level of controlled, connected advice-giving.
Model Dialogue
Ipò: Ìyá Kúmọ́lá wá sí ilé Adé láti bi ìmọ̀ràn nípa ìrìn àjò rẹ̀ lọ sí ìlú mìíràn.
Setting: Ìyá Kúmọ́lá comes to Adé's house to ask for advice about her trip to another town.
Guided Practice
- Write one sentence with a condition using bí.
- Write one sentence with a time clause using nígbà tí.
- Write one sentence giving a reason using nítorí, and one giving a result using torí náà.
- Write one sentence with obligation using gbọ́dọ̀ and one with ability or permission using lè.
- Write one warning or piece of safety advice using má.
- Combine a condition or reason with an obligation, ability, or prohibition in a single two-sentence piece of advice.
Listening Practice
Ask an instructor, study partner, or qualified Yorùbá speaker to read the following four lines at a natural conversational pace. For each, identify whether it is a condition, a reason, an obligation/ability statement, or a warning.
If no speaker is available, this is a Listening Script for Independent Use. Read each line aloud, cover it, then complete the task. Machine text-to-speech must be checked by a qualified Yorùbá speaker before use as a pronunciation model.
1. "Bí òjò bá rọ̀, má jáde lọ láìsí gbòngbò."
2. "Ọkọ̀ akérò lè pẹ́, nítorí ọ̀nà náà máa ń dí."
3. "O gbọ́dọ̀ mú owó tó tó."
4. "Má fi ẹrù rẹ sílẹ̀ láìsí àkíyèsí."
| Gbólóhùn | Condition / Reason / Obligation-Ability / Warning |
|---|---|
| 1 | ______ |
| 2 | ______ |
| 3 | ______ |
| 4 | ______ |
Speaking Practice
Pẹ̀lú alábàáṣepọ̀ — With a partner
One partner describes a trip, task, or event they are about to undertake (a journey, a first day at work, a visit to a clinic). The other partner gives advice using at least one condition or reason, one obligation or ability statement, and one warning. Switch roles with a new situation.
Fún àwọn tí ń kọ́ nìkọ̀ọ̀kan — Solo alternative
Record yourself giving advice to an imaginary traveler or first-time visitor, using a condition, a reason, an obligation or ability statement, and a warning.
Reading Practice
Àpẹẹrẹ — Ìmọ̀ràn Fún Ìrìn Àjò
Bí ẹnikẹ́ni bá fẹ́ rin ìrìn àjò lọ sí ìlú mìíràn, ó gbọ́dọ̀ múra sílẹ̀ dáradára. Ẹnìkan gbọ́dọ̀ mú ẹ̀rí ìdánimọ̀ rẹ̀ àti owó tó tó, nítorí ohun kan lè ṣẹlẹ̀ ní ọ̀nà tí a kò retí.

Gloss: If anyone wants to travel to another town, they must prepare well. One must bring one's identification and enough money, because something unexpected can happen along the way. When the bus is preparing to leave, one can ask the station workers for help if something goes wrong. Do not ever leave your luggage unattended, because there is danger. So, one must be careful, and one should speak to one's family when one arrives, so that they will not worry.
1. What two things must a traveler bring, according to the passage?
2. What can a traveler do if something goes wrong at the bus station?
3. Why should a traveler contact their family upon arrival?
Writing Workshop
Choose one real or invented situation in which someone needs practical advice (a trip, a new job, a medical appointment, a first visit to an office).
Iṣẹ́ rẹ — Your task: Write a short advice note of 60–80 words following the steps above.
- Every ẹ, ọ, and ṣ is correctly dot-underlined.
- Every required high and low tone is marked, including in gbọ́dọ̀, lè, and má.
- The note includes at least one condition or time clause.
- The note includes at least one reason and one result.
- The note includes at least one obligation, one ability/permission statement, and one warning.
Culture and Communication
In many Yorùbá-speaking communities, advice to someone preparing for a journey, a new responsibility, or an uncertain situation is commonly framed with care for the listener's wellbeing rather than as a list of blunt commands. Speakers often pair an obligation or warning with a reason, so that the advice sounds protective rather than controlling. Closing well-wishes, such as a short blessing for safe travel, commonly accompany practical advice of this kind, though the specific wording varies by family, region, and religious background.
Common Mistakes
Error: *O lè mú ẹ̀rí ìdánimọ̀ rẹ. when the intended meaning is a strict requirement, not an option.
Correction: O gbọ́dọ̀ mú ẹ̀rí ìdánimọ̀ rẹ. Gbọ́dọ̀ expresses a requirement or obligation, while lè expresses ability or permission; the two particles are not interchangeable, even though both come directly before the verb.
Error: *Fi ẹrù rẹ sílẹ̀ má láìsí àkíyèsí. inserting má in the middle of the verb phrase.
Correction: Má fi ẹrù rẹ sílẹ̀ láìsí àkíyèsí. Má must come directly before the main verb at the start of the prohibition, not after it or in the middle of the verb phrase.
Chapter Review
Apá A — Ìdámọ̀ Gbólóhùn (Sentence Identification)
1. For each of the four Listening Practice lines, identify whether it is a condition, a reason, an obligation/ability statement, or a warning.
Apá B — Ìmọ̀ràn àti Ìdí (Advice and Reasons)
1. Write two sentences giving advice about a trip or new task, each using a different connector (bí, nígbà tí, nítorí, or torí náà).
2. Write one sentence with gbọ́dọ̀ and one with lè about the same situation.
3. Write one warning using má that includes a reason using nítorí.
Ìfojúsí ẹkọ̀ tẹ́lẹ̀ — Cumulative review check
Before moving to Chapter 18, confirm you can still do the following using only Volume I and Chapters 1–17:
- Identify a person, thing, or place using ni, and ask a clarification question with ta ni, kí ni, or níbo ni.
- State a condition using bí and a time relationship using nígbà tí.
- Give a reason using nítorí and a result using torí náà.
- Express obligation using gbọ́dọ̀ and ability or permission using lè.
- Give a warning or safety caution using má.
Practical Performance Task
Iṣẹ́ aṣeyọrí — Abala 17
Fífún Ni Ìmọ̀ràn — Giving advice
Perform (live or recorded) a short exchange with a partner or listener in which one person asks for advice about an upcoming trip, task, or event, and the other gives advice using a condition or reason, an obligation or ability statement, and a warning. Afterward, complete the written task sequence below.
- Speaking: Perform the advice-giving exchange aloud, covering at least one condition/reason, one obligation/ability statement, and one warning.
- Written task 1: Write the advice note from the Writing Workshop.
- Written task 2: Answer the Reading Practice comprehension questions in complete Yorùbá sentences.
- Written task 3: Complete the Chapter Review, Apá A and Apá B, in full.
- Keep all writing fully tone-marked and dot-underlined throughout.
Assessment note: This chapter develops basic if/when/reason connectors as controlled formulas and evaluates independent, consolidated use of gbọ́dọ̀ and lè alongside advice- and safety-oriented use of má. It is evaluated on correct particle placement, accurate condition/reason connectors, clear distinction between obligation and ability, and sustained tone and orthographic accuracy across a spoken exchange and a written note.
