Language Structures And Functions Notes, Quizzes & Revision

What this note covers

Clear, practical explanations of key language structures (words, phrases, clauses, sentence types) and the main functions (what language does: inform, instruct, persuade, etc.). Examples use Kenyan situations (school, market, matatu, weather).

1. Important terms (quick)

• Noun: name of person, place, thing or idea (e.g., teacher, Nairobi, chai).
• Verb: action or state (e.g., run, eat, is).
• Adjective: describes a noun (e.g., green, tall).
• Adverb: describes a verb/adjective (e.g., quickly, very).
• Pronoun: replaces a noun (e.g., he, they, it).
• Preposition: shows relation (e.g., in, on, at, near).
• Conjunction: joins words/clauses (e.g., and, but, because).
• Determiner: words like a, an, the, this, those.

2. Sentence structure basics

Every simple sentence needs a subject and a predicate (verb + rest).

3. Types of sentences

• Declarative — gives information. (e.g., "The market opens at 8 a.m.")
• Interrogative — asks a question. (e.g., "When does the market open?")
• Imperative — gives a command or request. (e.g., "Bring the receipts.")
• Exclamatory — expresses strong feeling. (e.g., "What a busy day at the boda boda stage!")

4. Phrases and clauses

Phrase: group of words without both subject and verb (e.g., "in the afternoon").

Clause: group of words with a subject and verb. Types:

• Main (independent) clause: can stand alone. ("She sold vegetables.")
• Subordinate (dependent) clause: needs main clause. ("because she woke up early")
• Common subordinate clauses: noun, relative, adverbial.

5. Tense, aspect and time

Tense shows time (past, present, future). Aspect shows how the action takes place (simple, continuous, perfect).

• Simple present: I sell vegetables. (habit)
• Present continuous: I am selling vegetables. (now)
• Simple past: I sold vegetables. (finished)
• Present perfect: I have sold vegetables. (past action with present effect)
• Future (will/going to): I will sell; I am going to sell.

6. Modality and tone

Modals express ability, permission, obligation, likelihood: can, may, must, should, might.

7. Active and passive voice

Active: subject performs action. Passive: subject receives action. Passive often used in formal or when doer is unknown.

8. Reported (indirect) speech

When we tell what someone said, we often change tense, pronouns and time words.

9. Cohesion and paragraphing

Use linking words to connect ideas: and, but, because, however, therefore, then. Keep one main idea per paragraph.

10. Functions of language — what language does

• To inform: news, reports, facts. ("The harvest is ready.")
• To instruct: directions, recipes, rules. ("Turn left at the bus stop.")
• To persuade: adverts, speeches. ("Buy fair-trade coffee.")
• To entertain: stories, jokes. ("Once upon a time...")
• To express feelings: emotive language. ("I am very happy today!")
• To socialize: greetings and small talk. ("How are you?")

11. Register and formality

Choose words and structures to match the situation:

• Formal: reports, letters to officials — use full sentences and polite modals. ("I would like to request...")
• Informal: friends, family — contractions and slang are okay. ("I'm going to the shop.")

12. Common errors for learners in Kenya (and how to avoid them)

• Subject–verb agreement: "She go" → "She goes". Check the subject (singular/plural).
• Tense consistency: Mixing past and present in one sentence. Keep the same time unless there is reason to change.
• Wrong prepositions: "Depend of" → "depend on". Learn common collocations (depend on, interested in).
• Articles: Omit or misuse 'a', 'an', 'the'. Use 'the' for specific items (the bus), 'a/an' for any one of many (a bus).
• Direct translation: Avoid translating phrases word-for-word from Kiswahili or a local language (structure differs).
• Double negatives: "I don't know nothing." → "I don't know anything." or "I know nothing."

13. Quick practice (short exercises)

1. Change to passive: "They harvest the tea in the morning." → Answer: "The tea is harvested in the morning."
2. Report this: Teacher says, "You must submit your essay on Friday." → Answer: The teacher said that we had to submit our essays on Friday / that we must submit our essays on Friday (use reported tense).
3. Identify function: "Please vote for cleaner water sources." → Answer: Persuade (appeal).
4. Correct the error: "He don't like ugali." → Answer: "He doesn't like ugali."

Practical tips for pupils (age_replace)

• Read short Kenyan news items or school notices to see sentence patterns.
• When writing, decide: what is my purpose? (inform, instruct, persuade) — then choose structure and tone.
• Practice speaking with classmates: convert direct speech to reported speech aloud.
• Use simple checklists: subject–verb agreement, correct tense, punctuation.
