Module 4.1: Grammar and Usage


1. ARRANGEMENT OF ADJECTIVES

Meaning of Adjectives

An adjective is a word that describes or modifies a noun or pronoun. It gives more information about size, colour, age, shape, origin, material, quantity, or quality.

When more than one adjective is used to describe a noun, they must follow a correct sequence or order. This order is important in English grammar and is commonly tested in the GTLE.


Standard Order of Adjectives

The generally accepted order of adjectives in English is:

  1. Opinion – what you think about something

  2. Size – how big or small

  3. Age – how old or new

  4. Shape – round, square, flat

  5. Colour – red, blue, black

  6. Origin – Ghanaian, African, British

  7. Material – wood, plastic, metal

  8. Purpose – sleeping (as in sleeping bag)

📌 Mnemonic:
OSASCOMP
(Opinion, Size, Age, Shape, Colour, Origin, Material, Purpose)


Explanation

When adjectives are placed in the wrong order, the sentence sounds unnatural and incorrect. Native speakers may not know the rule consciously, but they follow it naturally.


Examples

  1. Correct:

    • She bought a beautiful small new round brown Ghanaian wooden table.

  2. Incorrect:

    • She bought a wooden Ghanaian brown round new small beautiful table.

  3. Correct:

    • The teacher wore a smart long old white Nigerian cotton dress.


GTLE Tip

In exams, look out for:

  • Jumbled adjectives

  • Options that sound “odd”
    Choose the option that follows the OSASCOMP order.


2. CONCORD (AGREEMENT)

Concord refers to agreement between parts of a sentence, especially:

  • Subject–verb agreement

  • Pronoun–antecedent agreement


A. SUBJECT–VERB AGREEMENT

Meaning

Subject–verb agreement means that the verb must agree with the subject in number and person.

  • Singular subject → singular verb

  • Plural subject → plural verb


Key Rules and Explanations

Rule 1: Singular Subjects Take Singular Verbs

  • He teaches English.

  • The child likes reading.

Rule 2: Plural Subjects Take Plural Verbs

  • They teach English.

  • The children like reading.


Rule 3: Words like everyone, somebody, each are singular

  • Everyone is present.

  • Each of the pupils has a book.


Rule 4: Compound subjects joined by and take plural verbs

  • Ama and Kofi are teachers.

But when the compound subject refers to one idea, use singular:

  • Rice and beans is my favourite food.


Examples

  1. Correct:

    • The teacher explains the lesson clearly.

  2. Incorrect:

    • The teacher explain the lesson clearly.

  3. Correct:

    • All the students have written the test.


B. PRONOUN–ANTECEDENT AGREEMENT

Meaning

A pronoun must agree with its antecedent (the noun it replaces) in:

  • Number

  • Gender

  • Person


Explanation

If the antecedent is singular, the pronoun must be singular.
If the antecedent is plural, the pronoun must be plural.


Examples

  1. Correct:

    • Every student must submit his or her assignment.

  2. Incorrect:

    • Every student must submit their assignment. (formal exam context)

  3. Correct:

    • The teachers finished their work early.


3. SEQUENCE OF TENSE

Meaning

Sequence of tense refers to the logical relationship between tenses in a sentence, especially in reported speech and complex sentences.


Explanation

When the main clause is in the past tense, the verb in the subordinate clause usually changes to the past as well.


Common Patterns

Direct Tense Reported Tense
Present Past
Past Past perfect
Will Would

Examples

  1. Direct:

    • He says, “I am tired.”
      Reported:

    • He said that he was tired.

  2. Direct:

    • The teacher said, “The test has ended.”
      Reported:

    • The teacher said that the test had ended.

  3. Correct:

    • She knew that the pupils were ready.


GTLE Tip

Watch out for:

  • Mixed tenses in one sentence

  • Incorrect tense shifts


4. CONDITIONAL SENTENCES

Meaning

Conditional sentences express situations and their possible results. They usually contain:

  • An if-clause (condition)

  • A main clause (result)


TYPES OF CONDITIONAL SENTENCES


A. ZERO CONDITIONAL

Used for general truths and scientific facts.

Structure:
If + present tense, present tense

Examples:

  1. If you heat ice, it melts.

  2. If students study hard, they perform well.


B. FIRST CONDITIONAL

Used for real and possible future situations.

Structure:
If + present tense, will + base verb

Examples:

  1. If you revise well, you will pass the exam.

  2. If it rains, the match will be cancelled.


C. SECOND CONDITIONAL

Used for unreal or unlikely present situations.

Structure:
If + past tense, would + base verb

Examples:

  1. If I were the headteacher, I would improve discipline.

  2. If she studied harder, she would pass.


D. THIRD CONDITIONAL

Used for imaginary past situations.

Structure:
If + past perfect, would have + past participle

Examples:

  1. If he had studied, he would have passed.

  2. If they had arrived earlier, they would have met the principal.


5. ACTIVE AND PASSIVE VOICE


A. ACTIVE VOICE

Meaning

A sentence is in the active voice when the subject performs the action.

Structure:
Subject + Verb + Object


Examples

  1. The teacher explained the lesson.

  2. The pupils cleaned the classroom.


B. PASSIVE VOICE

Meaning

A sentence is in the passive voice when the subject receives the action.

Structure:
Object + auxiliary verb + past participle (+ by agent)


Examples

  1. The lesson was explained by the teacher.

  2. The classroom was cleaned by the pupils.


Explanation

Passive voice is often used when:

  • The doer of the action is unknown

  • The action is more important than the doer


More Examples

  1. Active:

    • The headteacher punished the students.
      Passive:

    • The students were punished by the headteacher.

  2. Active:

    • Someone stole my book.
      Passive:

    • My book was stolen.


GTLE Tip

You may be asked to:

  • Change active to passive

  • Identify voice errors

  • Choose correct auxiliary verbs (is, was, were, has been)
