Revise the key ideas

Words and phrases

  • Word classes — A word class describes a word's grammatical behaviour. Identify its job in a particular sentence: “paint” is a noun in “the paint dried” but a verb in “we paint doors”. Meaning alone is not a reliable test.
  • Nouns — Nouns can name people, places, objects, ideas or processes. Justice and arrival are nouns even though you cannot touch them. Words such as the often come before nouns: “the arrival”. Many nouns also have plurals. Uncountable nouns name things not normally counted as separate items, such as furniture, so “furnitures” is not a useful test. Use several clues.
  • Proper and common nouns — A proper noun names a particular person or place, such as Hermia or Athens, and normally begins with a capital. A common noun names a category, such as daughter or city. Capitalisation alone does not explain a word's role.
  • Determiners — Determiners introduce noun phrases and help specify reference or quantity: “the letter”, “this letter”, “some letters”. “A” and “an” are articles used before singular count nouns; choose between them by the following sound, as in “an hour”.
  • Pronouns and reference — Pronouns can stand in place of noun phrases: “Hermia read the letter. She folded it.” Make clear who “she” and what “it” refer to. “It” can also have a grammatical role without referring to an object, as in “It is raining”.
  • Adjectives — Adjectives often modify nouns or follow a linking verb: “the anxious messenger”; “the messenger seemed anxious”. They can express judgements as well as physical qualities. Adding many adjectives does not automatically make description precise.
  • Verbs beyond action — Verbs can express actions, events or states: run, happen, know and be. Several verbs can work together: in “She has been waiting”, the verb phrase is has been waiting, not just waiting. Find the whole group when asking when something happens and how the event is presented, for example as continuing. These choices are explored under tense and aspect below.
  • Auxiliaries and modals — Auxiliary verbs help form constructions: “has arrived”, “is waiting”, “was sent”. Modal verbs such as might, must and should express possibility, obligation or judgement. “Might return” makes a weaker commitment than “will return”.
  • Adverbs and adverbials — Adverbs can modify verbs, adjectives or other adverbs: “spoke softly”, “very quiet”. An adverbial is a function giving circumstances such as time or place; “after the meeting” is a phrase functioning as an adverbial, not a single adverb.
  • Prepositions — Prepositions head phrases such as “under the bridge”, “after dinner” and “because of the delay”. They express relationships including place, time and cause. A preposition is not simply any word telling us where something is.
  • Conjunctions — Coordinating conjunctions link equal parts: in “Lysander waited and Hermia listened”, and joins two main clauses that could each be a sentence. Subordinating conjunctions introduce clauses that depend on another part: “although Lysander waited” needs something such as “Hermia left”. However links ideas but cannot normally join two main clauses with only a comma: use “Lysander waited. However, Hermia left.”
  • Phrases and heads — A phrase is organised around a head word. “The frightened young messenger” is a noun phrase with messenger as its head. A phrase may contain just one word; expanded noun phrases add useful detail rather than changing the head's class.
    The phrase the anxious messenger has determiner the, adjective anxious and head noun messenger. All belong to one noun phrase.

Clauses and relationships

  • Clauses — A clause is a grammatical unit built around a verb and usually a subject. In “Hermia waited”, Hermia is the subject and waited is the verb. Commands such as “Wait here” normally leave the subject you unspoken. A clause may need another clause to complete the meaning, as with “because Hermia waited”; having a verb does not automatically make a complete sentence.
  • Subject and object — In “Puck carried the message”, Puck is the subject and the message is the object. Subjects are grammatical roles, not always people doing actions: “The message was carried” makes the message the subject.
    In Puck carried the message, Puck is subject, carried is verb and the message is object. Roles differ from word classes.

  • Main clauses — A main clause can function as a complete sentence: “The gate opened.” A sentence may contain several clauses. Find its finite verb and subject, then check which other units depend on it.
  • Subordinate clauses — A subordinate clause depends on another part of a sentence. “Because the gate opened” leaves the reader expecting the main clause. Attach it: “Because the gate opened, we entered.” The reason is now connected to an event.
    Because it rained is a subordinate clause giving a reason. We waited is the main clause. Together they form a complex sentence.

  • Relative clauses — Relative clauses modify nouns: “The letter that arrived yesterday was damaged.” The clause “that arrived yesterday” identifies the letter. In “The letter, which arrived yesterday, was damaged”, commas present the arrival as additional information.
  • Finite and non-finite verbs — A finite verb places a clause in the past or present and can form a complete verb phrase: “she waits”; “she waited”. Non-finite forms, such as to wait and waiting, do not do this on their own. In “she is waiting”, is is finite and waiting is non-finite. “Waiting by the gate, Hermia heard footsteps” contains a non-finite clause whose understood subject is Hermia.
  • Simple sentences — A simple sentence contains one main clause, even if it has a long noun phrase or several modifiers: “The frightened young messenger beside the old bridge waited patiently.” Simple does not mean short or easy.
  • Compound sentences — A compound sentence links main clauses, often with and, but or or: “The gate opened, but nobody entered.” Each clause can stand alone. Joining two nouns with and does not by itself make a compound sentence.
  • Complex sentences — A complex sentence contains a main clause and at least one subordinate clause: “When the gate opened, we entered.” “I know that she left” is also complex. Judge the clause relationships, not sentence length.
  • Sentence functions — Sentences can be statements (“It is noisy”), questions (“Is it noisy?”), commands (“Be quiet”) or exclamations (“What a noise that was!”). An exclamation has a particular grammatical form; adding ! to a command does not change that form. Grammar and purpose can differ: “You are leaving?” has statement word order but can be spoken to ask a question.

Control and effect

  • Agreement — In Standard English, a singular subject usually takes a singular present-tense verb: “The list of names is missing.” The subject head list controls agreement, not the nearest plural noun names. Check the whole noun phrase.
  • Tense and time — Past and present verb forms help locate events, but tense and real time are not identical: “The train leaves tomorrow” uses present tense for a future event. Maintain a clear time frame unless a deliberate shift is needed.
  • Aspect — Aspect shows how a verb presents an event in relation to time. Progressive forms present it as in progress: “She was waiting when the bell rang.” Perfect forms look back from another time: “When I arrived, she had left” places her leaving before my arrival. Compare with “I arrived and she left”, which would normally suggest that she left after I arrived. Read the surrounding sentences to check the relationship.
  • Active and passive — In the active clause “The guard opened the gate”, the guard is the subject. In the passive clause “The gate was opened by the guard”, the gate is the subject and gets the first attention. The agent means whoever or whatever does the action: here, the guard. We can leave the agent out: “The gate was opened.” Choose the focus you need.
    The guard opened the gate is active. The gate was opened by the guard is passive. The event is similar but the subject changes.

  • Ambiguous modifiers — Place a modifying phrase next to what it describes. “Walking to school, the rain soaked me” wrongly suggests the rain was walking. “Walking to school, I was soaked by the rain” gives the opening clause a sensible subject.
  • Worked sentence revision — “The gate opened we ran” joins main clauses without a boundary. “The gate opened, so we ran” gives a causal connection; “When the gate opened, we ran” makes the opening a time condition. Choose the relationship you mean, not just a longer sentence.
  • Purposeful variation — A short sentence can mark a turning point, while subordination can establish cause, contrast or qualification. Neither length guarantees an effect. Explain how a specific sentence works in its context and vary structures without losing accuracy.
  • Grammar in reading — Compare “The crowd attacked him” with “He was attacked”. The second foregrounds the victim and leaves the agent unnamed. Grammar analysis should connect a precise construction to the presentation of events, not merely label it.
  • Subjunctive choices — The subjunctive appears in some formal demands and imagined situations. Compare “She is present” with “The committee requires that she be present”: be keeps the base form instead of changing to is. “If I were in charge” imagines a situation; “I was in charge” states a past situation. Choose these forms for their meaning and level of formality, rather than adding them everywhere.
