Word classes in context

GCSE
Identify word classes at GCSE depth: noun, verb, adjective, adverb, pronoun, preposition, conjunction, determiner
Video lesson: Word classes in contextComing soon
Context. A word's class depends on its job in the sentence, not only on its spelling. Read the model passage, and decide the class of each word by asking what it does: names something (noun), shows an action (verb), describes (adjective or adverb), replaces a noun (pronoun), or joins (conjunction).

Model passage: The letter (original, three paragraphs)

1The letter arrived on a Tuesday. Lena had been waiting for it since March, and she had almost stopped hoping. She opened it carefully at the kitchen table. The company had offered her a place on the training scheme, and it would begin in September. It was the first offer she had received in a year.

2She read the letter twice, then a third time. Her hands were shaking. Outside, a van was reversing down the lane. For a moment she did not move at all. The training would last two years, and she would be paid while she learned. Her brother had promised to celebrate with her, and she could already hear him laughing in the hall.

3"Tell me it is true," she whispered to the empty kitchen. Nobody answered, but the kettle clicked off, as if the house itself had heard. Lena smiled at the sound, feeling foolish and happy at once.

Key ideas

  • Noun: a naming word (letter, Tuesday, Lena).
  • Verb: an action or state (arrived, was shaking).
  • Adjective describes a noun (kitchen table is a noun phrase; empty kitchen uses an adjective).
  • Adverb describes a verb, adjective or adverb, often ending in -ly (carefully, twice).
  • Determiner comes before a noun (the, a, her).
Worked example 10.1.1
What word class is "carefully" in "She opened it carefully"? Write one word.

Method. Ask what the word describes.

  1. Find what it describes. Carefully describes how she opened it, which is a verb.
    opened
  2. Name the class. A word that describes a verb is an adverb.
    adverb
  3. Write the answer.
    adverb

Check. Carefully describes the verb opened. ✓

Worked example 10.1.2
Which word class is "the" in "the kitchen table"? Choose one: determiner, adjective or pronoun.

Method. Test each choice against the text.

  1. Read what the question asks for. Decide what the sentence or the text needs.
  2. Test the choice. The comes before a noun and introduces it.
    determiner fits
  3. Reject the other choices. The is not describing the noun, and it does not replace a noun.
    adjective and pronoun do not fit
  4. Write the answer.
    determiner

Check. The choice fits the text. ✓

Worked example 10.1.3
What word class is "and" in "Lena had been waiting, and she had almost stopped hoping"? Write one word.

Method. Look at what the word joins.

  1. Find what it joins. And joins two clauses.
    and she had almost stopped hoping
  2. Name the class. A word that joins clauses is a conjunction.
    conjunction
  3. Write the answer.
    conjunction

Check. And is a conjunction. ✓

10.2

Sentence types: simple, compound, complex and minor

GCSE
Identify simple, compound, complex and minor sentences; main, subordinate and relative clauses
Video lesson: Sentence types: simple, compound, complex and minorComing soon
Context. A simple sentence has one main clause. A compound sentence joins two main clauses with a conjunction such as and, but or so. A complex sentence has one main clause and at least one subordinate clause, which cannot stand alone. A minor sentence has no verb.

Key ideas

  • Simple: one main clause.
  • Compound: two main clauses joined by and, but or so.
  • Complex: a main clause and a subordinate clause (after when, although, because, as if).
  • Relative clause: a subordinate clause that begins with who, which, that or whose.
Worked example 10.2.1
Which sentence type is "The letter arrived on a Tuesday"? Choose one: simple, compound or complex.

Method. Test each choice against the text.

  1. Read what the question asks for. Decide what the sentence or the text needs.
  2. Test the choice. It has one main clause and no conjunction joining two clauses.
    simple fits
  3. Reject the other choices. It has no and or but, and no subordinate clause beginning with a joining word.
    compound and complex do not fit
  4. Write the answer.
    simple

Check. The choice fits the text. ✓

Worked example 10.2.2
Is "She opened it carefully at the kitchen table" simple or compound? Write one word.

Method. Count the main clauses.

  1. Find the verbs. The sentence has one main verb, opened.
    opened
  2. Count the clauses. There is one main clause and no joining conjunction.
    one main clause
  3. Name the type. One main clause makes a simple sentence.
    simple
  4. Write the answer.
    simple

Check. One main clause. ✓

Worked example 10.2.3
Name the subordinate clause in "The kettle clicked off, as if the house itself had heard."

Method. Find the clause that cannot stand alone.

  1. Find the joining word. As if begins a subordinate clause.
    as if
  2. Check it stands alone. As if the house itself had heard does not make sense alone.
    does not make sense alone
  3. Name it. The subordinate clause is as if the house itself had heard.
    as if the house itself had heard
  4. Write the answer.
    as if the house itself had heard

Check. The subordinate clause depends on the main clause. ✓

Tense, aspect and subject-verb agreement

GCSE
Use subject-verb agreement correctly; identify and use tense and aspect (past, present, future, progressive, perfect)
Video lesson: Tense, aspect and subject-verb agreementComing soon
Context. Tense shows when an action happens. Aspect shows how it happens: simple, progressive (was waiting) or perfect (had waited). The verb must agree with its subject: one subject takes a singular verb; two or more take a plural verb.
TenseFormExample
Present simpleverb (+s)She opens the letter.
Past simpleverb (-ed or irregular)She opened the letter.
Present progressiveam/is/are + -ingShe is opening the letter.
Past progressivewas/were + -ingShe was opening the letter.
Present perfecthave/has + past participleShe has opened the letter.
Past perfecthad + past participleShe had opened the letter.
Futurewill + verbShe will open the letter.

Key ideas

  • Past simple: she opened. Past progressive: she was opening. Past perfect: she had opened.
  • Agreement: the letter was (singular); the letters were (plural).
  • Each, every, either and neither take a singular verb.
  • With neither ... nor, the verb agrees with the nearer subject.
Worked example 10.3.1
What tense is "Her hands were shaking"? Write the tense name.

Method. Look at the auxiliary and the -ing form.

  1. Find the auxiliary. Were is the past of be.
    were
  2. Find the -ing form. Shaking shows the action in progress.
    shaking
  3. Name the tense. Past plus -ing is the past progressive.
    past progressive
  4. Write the answer.
    past progressive

Check. Were plus -ing is past progressive. ✓

Worked example 10.3.2
Which verb completes "Neither the pupils nor the teacher ___ ready"? Choose one: was, were or be.

Method. Test each choice against the text.

  1. Read what the question asks for. Decide what the sentence or the text needs.
  2. Test the choice. With neither ... nor, the verb agrees with the nearer subject, the teacher.
    was fits
  3. Reject the other choices. Were would agree with the pupils, but the nearer subject is the teacher.

Worked example 10.3.3
Choose the correct form: "Each of the letters ___ important." Write is or are.

Method. Each takes a singular verb.

    Each
  2. Check the rule. Each takes a singular verb.
    singular
  3. Choose. The correct form is is.

Mood and voice

GCSE
Identify mood (indicative, imperative, subjunctive in simple use) and active and passive voice; change between them
Video lesson: Mood and voiceComing soon
Context. Mood is the attitude of a verb. Most sentences are indicative (they state or ask). Imperatives give orders. The subjunctive appears in simple forms such as if I were you. Voice shows whether the subject does the action (active) or has it done to them (passive).
MoodWhat it doesExample
Indicativestates facts or asks questionsThe letter arrived.
Imperativegives an order or requestOpen the letter.
Subjunctive (simple use)expresses a wish, or a condition contrary to factIf I were you, I would wait.

Key ideas

  • Indicative: states facts or asks questions.
  • Imperative: gives an order or request, often without a subject: Tell me.
  • Subjunctive (simple use): If I were you; it is vital that he be there.
  • Active: Lena opened the letter. Passive: The letter was opened by Lena.
Worked example 10.4.1
What is the mood of "Tell me it is true"? Write one word.

Method. Look for a verb that gives an order.

Method. Test each choice against the text.

  1. Read what the question asks for. Decide what the sentence or the text needs.
  2. Test the choice. The subject, the letter, receives the action, with was opened.
    The letter was opened by Lena. fits

The effect of sentence type, tense and voice

GCSE
Explain the effect of sentence type, tense and voice on a reader
Video lesson: The effect of sentence type, tense and voiceComing soon
Context. Grammar choices create effects. A short sentence creates a pause. A present tense makes an event feel immediate. A passive voice can hide the doer. Ask: what does this choice do to the reader, and why did the writer choose it?

Key ideas

  • A short sentence creates a pause or tension.
  • Present tense creates immediacy; past tense creates distance or reflection.
  • Passive voice can hide or delay the doer, and can suggest that the action matters more than the doer.
  • Explain the effect in a full sentence: the choice + what it does + the effect on the reader.
Worked example 10.5.1
What effect does the short sentence "For a moment she did not move at all." create? Give one effect.

Method. Look at its length and what it describes.

  1. Look at the length. The sentence is short after longer ones.
    For a moment she did not move at all
  2. Explain the effect. The short sentence slows the pace.
    slows the pace
  3. Give the effect. It creates a pause and tension.
    a pause and tension
  4. Write the answer.
    a pause and tension

Check. Short sentences create pauses. ✓

Worked example 10.5.2
Which effect does the present tense in "Outside, a van is reversing" create? Choose one: immediacy, as if it is happening now, distance, as if it happened long ago or humour.

Method. Test each choice against the text.

  1. Read what the question asks for. Decide what the sentence or the text needs.
  2. Test the choice. The present tense places the reader in the moment.
    immediacy, as if it is happening now fits
  3. Reject the other choices. Distance would come from the past tense, and humour is not created by this tense.
    distance, as if it happened long ago and humour do not fit
  4. Write the answer.
    immediacy, as if it is happening now

Check. The choice fits the text. ✓

Worked example 10.5.3
Why might a writer use a passive sentence such as "The letter was opened"? Give one reason.

Method. Think about what the passive puts first.

  1. Find the focus. The passive places the letter first.
    The letter was opened
  2. Think about the doer. The doer is not named, so the focus stays on the action.
    not named
  3. Give the reason. The writer focuses on the letter rather than the person.
    focus on the letter
  4. Write the answer.
    to focus on the letter rather than the person who opened it

Check. The passive shifts the focus. ✓
