Chapter Objectives
By the end of this chapter, you will be able to:
- Interpret public health notices, advisories, and announcements at a connected-discourse level.
- Give and understand prohibitions using má in health and safety contexts.
- Express obligation and recommended action using ó yẹ kí and related modal frames.
- State conditions using bí and tí clauses in practical guidance.
- Explain cause and result using torí pé and nítorí náà in a health context.
- Recognize (receptively) how contrastive focus and relative clauses can sharpen a piece of public guidance, without being required to produce them independently in new forms.
- Write a short, accurate health information note using full tone marks and diacritics.
Opening Communication Scenario
A community health worker has posted a notice near the borehole that Adé's neighborhood recently repaired, reminding residents how to keep the water safe and what to do if someone falls ill. Your neighbor, who missed the meeting, asks you to explain the notice and tell them what they should and should not do.
- This chapter develops prohibitions, obligation, condition, and cause/result clauses already introduced earlier in the volume, now applied to public health and safety guidance.
- Contrastive focus, relative clauses with expanded structure, and complement clauses may appear for recognition only in this chapter's readings and listening passages; you are not expected to produce new forms of them independently yet.
- By the end of this chapter, you should be able to explain a piece of public health guidance clearly, including what to do, what to avoid, and why.
Core Vocabulary
The following vocabulary supports public health, safety, and advisory communication. Productive items are marked for active use; a small number of related items are receptive only at this stage.
| Yorùbá | English | Status |
|---|---|---|
| ìlera | health | Productive |
| àìsàn | illness; sickness | Productive |
| omi mímọ́ | clean water | Productive |
| ìṣọ́ra | caution; carefulness | Productive |
| ìkìlọ̀ | warning | Productive |
| ìwòsàn | treatment; healing | Productive |
| oníṣègùn | doctor; healer | Productive |
| ilé ìwòsàn | hospital; clinic | Productive |
| àjàrá / àjẹsára | vaccine; immunization | Productive |
| ìdílọ́wọ́ | prevention | Receptive |
| àkọsílẹ̀ ìlera | health record | Productive (recycled, Ch. 10) |
| ààbò | safety; protection | Productive |
Pronunciation Focus
Public announcements and warnings often use short, emphatic clauses with clear pauses between the prohibition, the reason, and the recommended action. Keep every tone mark accurate even when speaking with added emphasis; emphasis in Yorùbá is carried by rhythm, pausing, and volume, not by flattening or exaggerating tone.
- Practice the contrast between má (prohibition particle, low tone) and ma-initial words that are not the prohibition particle.
- Keep the dot-under vowels in ṣọ́ra, ẹ̀jẹ̀-type words, and ọjà-type words distinct and clear when reading a warning aloud.
- Read each sentence of the health notice below first slowly, phrase by phrase, then again at a natural announcement pace.
Grammar and Sentence Patterns
This chapter develops four connected systems already active in the volume — prohibition, obligation, condition, and cause/result — and applies them to public health guidance. No new particle or clause type is introduced for the first time; each pattern below builds on material already scheduled.
Prohibitions with má
Má (+ kí ó) + verb + object
má negates a command; it is distinct from the ordinary declarative negator kò and is used specifically for instructions and warnings.
Má mu omi tí kò mọ́.
Do not drink water that is not clean.
- Ẹ má fọwọ́ kan omi kànga náà kí ẹ tó fọ ọwọ́ yín. Do not touch the borehole water before you wash your hands. respectful plural prohibition + time clause (recycled)
Obligation with ó yẹ kí
- Ó yẹ kí gbogbo ènìyàn wẹ ọwọ́ wọn kí wọ́n tó jẹun. Everyone should wash their hands before they eat. obligation frame + purpose/time subordination (recycled from Ch. 7)
- Kò yẹ kí a fi omi tí a kò tíì sè fún àwọn ọmọdé. We should not give unboiled water to children. negated obligation frame
Condition with bí and tí
- Bí ara ẹnikẹ́ni bá gbóná jù, kí wọ́n lọ sí ilé ìwòsàn lẹ́sẹ̀kẹsẹ̀. If anyone's body becomes too hot (has a fever), they should go to the clinic immediately. bí conditional clause + obligation-style instruction
- Tí a bá tọ́jú kànga náà dáadáa, àìsàn yóò dín kù. If we take good care of the borehole, illness will decrease. tí-conditional + future-marked result clause
Cause and result with torí pé and nítorí náà
- Omi tí kò mọ́ máa ń fa àìsàn ikùn; nítorí náà, ẹ máa sè omi yín kí ẹ tó mu ún. Unclean water often causes stomach illness; therefore, boil your water before drinking it. habitual cause statement + nítorí náà result clause + prohibition-style recommendation
The listening and reading passages below contain a small number of contrastive focus phrases, a longer relative clause, and one complement clause after "wọ́n sọ pé" used only to make the health notice sound natural. These items remain receptive; you are not assessed on producing new instances of them in this chapter.
Model Dialogue
Ipò: Adé ń ṣàlàyé ìwé ìkéde ìlera tí a fi sí ẹ̀gbẹ́ kànga fún aládùúgbò rẹ̀.
Setting: Adé is explaining the health notice posted near the borehole to his neighbor.
Guided Practice
- Find one prohibition, one obligation statement, one condition, and one cause/result statement in the model dialogue.
- Rewrite the prohibition about touching the water so that it addresses a single person instead of a group.
- Combine a condition and an obligation into one sentence about what to do if someone has a fever.
- Identify the complement clause after "ó sọ pé" in Adé's second line and explain what it introduces.
Listening Practice
Ask an instructor, study partner, or qualified Yorùbá speaker to read the passage below aloud at a natural announcement pace, or read it aloud yourself and then cover it before answering.
If no speaker is available, this is a Listening Script for Independent Use. Machine text-to-speech must be checked by a qualified Yorùbá speaker before use as a pronunciation model.
"Ẹ ṣọ́ra, ará àdúgbò: kànga omi wa ti dára báyìí, ṣùgbọ́n ó yẹ kí gbogbo wa ṣọ́ ọ dáadáa. Ẹ má fọwọ́ kan omi náà pẹ̀lú ọwọ́ tí kò mọ́, kí ẹ sì máa sè omi náà kí ẹ tó fi fún àwọn ọmọdé mu, torí pé omi tí kò tíì sè lè fa àìsàn ikùn. Bí ẹnikẹ́ni bá ní ìgbẹ́ gbuuru tàbí bí ara wọn bá gbóná jù, kí a gbé wọn lọ sí ilé ìwòsàn àdúgbò lẹ́sẹ̀kẹsẹ̀, kì í ṣe kí a kọ́kọ́ gbìyànjú oògùn ilé fúnra wa.

1. What are residents told not to do with the borehole water, and why?
2. What should be done before giving water to children?
3. What should be done if someone has diarrhea or a high fever?
4. What did the doctor say about children who have not yet been vaccinated?
Iṣẹ́ rẹ — Your task: Answer the four questions above in complete Yorùbá sentences.
Speaking Practice
Tier 1 — Supported
Using the model dialogue as a guide, explain the health notice to a partner, including at least one prohibition and one obligation statement.
Tier 2 — Guided
Give spoken advice to a partner about a health or safety situation of your choice (for example, food safety, seasonal illness, or child safety), using at least one condition clause and one cause/result clause.
Tier 3 — Independent
Deliver a one-to-two-minute spoken public health announcement for your community, combining a prohibition, an obligation, a condition, and a cause/result statement, without reading directly from a script.
Reading Practice
Ìwé Ìkìlọ̀ Ìlera Àdúgbò
Sí gbogbo ará àdúgbò: omi mímọ́ ni kànga wa ń pèsè báyìí, ṣùgbọ́n ààbò rẹ̀ wà lọ́wọ́ gbogbo wa.

1. According to the notice, what must be done before giving the water to children, and why?
2. What condition-and-action pair does the notice give for diarrhea or high fever?
3. Identify the prohibition in the first sentence about touching the water, and restate it in your own words.
4. What responsibility does the notice place on "gbogbo wa" (all of us) at the end?
Iṣẹ́ rẹ — Your task: Answer the four questions above in complete Yorùbá sentences.
Writing Workshop
Write a short health information note of 60–100 words with full tone marks and dot-under letters throughout. Your note must include at least one prohibition, one obligation statement, one condition, and one cause/result statement, addressed to your community.
Include
- at least 1 prohibition with má
- at least 1 obligation with ó yẹ kí
- at least 1 condition clause (bí or tí)
- at least 1 cause/result pair (torí pé / nítorí náà)
Avoid
- producing new contrastive focus or relative-clause structures beyond recycled forms
- producing an independent new complement clause
- confusing má (prohibition) with kò (declarative negation)
- omitting tone marks or dot-under letters
- Every vowel that should carry a high or low tone mark has one.
- Every mid-tone syllable is left correctly unmarked.
ẹ,ọ, andṣare distinguished frome,o, andsthroughout.- The prohibition particle má is spelled and toned distinctly from the negator kò.
- No unscheduled grammar (new focus patterns, new relative-clause types, new particles) has been produced.
Culture and Communication
Public health guidance in many Yorùbá-speaking communities is often communicated as a shared responsibility rather than a set of individual instructions; notices frequently address "gbogbo wa" (all of us) and appeal to collective care for shared resources such as water sources. At the same time, it is common for health notices to explicitly recommend seeking care from a trained health worker or clinic rather than relying solely on home remedies for serious symptoms, while still respecting that home and traditional remedies remain part of everyday health practice for many families.
Common Mistakes
Error: Using the declarative negator in a prohibition, such as *Ẹ kò fọwọ́ kan omi náà when giving an instruction not to touch the water.
Correction: Use the prohibition particle for instructions and warnings: Ẹ má fọwọ́ kan omi náà ("do not touch the water"). Kò states that something is not the case; má instructs someone not to do something.
Error: Stating the recommended action without its triggering condition, such as *Kí a gbé e lọ sí ilé ìwòsàn alone, without saying under what circumstance this applies.
Correction: Keep the condition attached to the instruction: Bí ara ọmọ náà bá gbóná jù, kí a gbé e lọ sí ilé ìwòsàn lẹ́sẹ̀kẹsẹ̀ ("if the child's body becomes too hot, take them to the clinic immediately"). Without the condition, the guidance loses its practical meaning.
Chapter Summary
This chapter developed prohibition with má, obligation with ó yẹ kí, condition with bí and tí, and cause/result with torí pé and nítorí náà in the context of public health and safety guidance. Contrastive focus, an expanded relative clause, and a complement clause after "sọ pé" appeared for recognition only. Learners practiced interpreting, speaking, reading, and writing connected health information while maintaining full tone marking and dot-under orthography.
Chapter Review
Apá A — Ìṣàyẹ̀wò Gírámà (Grammar Check)
1. Explain the difference in function between má and kò, and give one example sentence for each.
2. Identify a sentence from this chapter that combines a condition clause with an obligation, and explain how the two parts work together.
Apá B — Ìṣàyẹ̀wò Ara Ẹni (Self-Check)
1. Which system (prohibition, obligation, condition, or cause/result) did you find easiest to use accurately in your own writing? Which was hardest?
2. Did you notice any of the recognition-only items (contrastive focus, longer relative clause, complement clause) in the reading or listening passage? What did they add to the meaning?
Ìfojúsí ẹkọ̀ tẹ́lẹ̀ — Cumulative review check
Before continuing to Chapter 12, confirm you can do the following:
- Form and understand prohibitions with má.
- Form and understand obligation statements with ó yẹ kí.
- Form and understand condition clauses with bí and tí.
- Form and understand cause/result statements with torí pé and nítorí náà.
- Combine these four systems into a single piece of practical guidance.
- Maintain full, accurate tone marking and dot-under orthography in health-related writing.
Practical Performance Task
Iṣẹ́ aṣeyọrí — Abala 11
Ìwé Ìkìlọ̀ Ìlera Mi — My Health Advisory
Produce a connected spoken and written health information note (based on the borehole scenario, or a real or invented health/safety topic of your choice) that includes a prohibition, an obligation, a condition, and a cause/result statement.
- Speaking: Deliver a one-to-two-minute spoken announcement (Speaking Practice, Tier 3).
- Writing: Submit your 60–100 word written health note (Writing Workshop).
- Self-review: Complete the Tone and Orthography Checkpoint for both your spoken notes and written note.
Assessment note: This task provides evidence of controlled use of prohibition, obligation, condition, and cause/result together. No new productive grammar beyond these four systems is assessed in this chapter.
Answer Key
Listening Practice Questions
- Residents are told not to touch the water with unclean hands, because contact with dirty hands can contaminate it.
- The water should be boiled before it is given to children to drink, because unboiled water can cause stomach illness.
- If someone has diarrhea or a high fever, they should be taken to the neighborhood clinic immediately, rather than trying home remedies first.
- The doctor said that children who have not yet been vaccinated should come to the clinic this week.
Reading Practice Questions
- The water must be boiled before it is given to children, because unboiled water can cause a serious illness.
- If someone begins to have diarrhea or a high fever, they should be taken to the clinic first, not treated at home.
- The prohibition is "ẹ má fi ọwọ́ tí kò mọ́ kan omi náà" ("do not touch the water with unclean hands"); restated, it means residents should keep their hands clean before touching the water.
- The notice places responsibility on everyone to stay alert and protect the borehole as shared property.
Guided Practice — Sample Responses
1. Prohibition: "ẹ má fọwọ́ kan omi náà kí ẹ tó fọ ọwọ́ yín"; obligation: "ó yẹ kí a sè omi náà kí a tó mu ún"; condition: "bí ara ọmọ náà bá gbóná jù..."; cause/result: "omi tí a kò sè lè fa àìsàn ikùn; nítorí náà..." 2. Sample singular form: "Má fọwọ́ kan omi náà kí o tó fọ ọwọ́ rẹ." 3. Sample combination: "Bí ara ẹnikẹ́ni bá gbóná jù, ó yẹ kí a gbé e lọ sí ilé ìwòsàn lẹ́sẹ̀kẹsẹ̀." 4. The complement clause "pé ìdọ̀tí lè bà á jẹ́" introduces what the notice states as the reason for the prohibition; it functions as the content of "ó sọ."
Chapter Review — Apá A
1. Kò negates a statement of fact (something is not the case); má negates a command or instruction (telling someone not to do something). Example with kò: "Omi náà kò mọ́" (the water is not clean). Example with má: "Ẹ má mu omi náà" (do not drink the water). 2. "Bí ara ọmọ náà bá gbóná jù, kí a gbé e lọ sí ilé ìwòsàn lẹ́sẹ̀kẹsẹ̀" combines a condition (a fever occurring) with an obligation-style instruction (taking the child to the clinic); the condition specifies when the obligation applies.
