A speech act is something a person does in speaking or writing, not merely the information that a sentence describes. ‘Could you send me the corrected page?’ normally performs a request. ‘I promise to return the book on Friday’ can undertake a commitment when used sincerely in an appropriate situation. ‘The session is cancelled’ may function as an announcement, but whether it officially changes the schedule depends on who says it and the relevant procedure.
Vocabulary becomes a practical technology when we recognise these actions. A learner can distinguish asking from ordering, informing from authorising, proposing from agreeing and apologising from explaining. The right words help people coordinate responsibilities and avoid treating a friendly suggestion as a compulsory rule or a casual remark as formal approval. The sentence’s grammar is not enough: context, speaker, authority, timing and the recipient’s understanding can alter its force.
This guide explains what speech acts are, why they matter and how to inspect them. It covers the classic distinctions introduced by J. L. Austin and developed by John Searle, then brings the idea into English comprehension, school notices, group work, digital messages and everyday decisions. Its original case studies and practice questions show how to ask what a statement does, what conditions make that action appropriate and which next response it makes relevant.

1. A sentence can perform an action
Suppose a classmate says, ‘Please close the window.’ This is normally a request directed at someone who can close it. The sentence has a grammatical form and literal meaning, but it is also being used to do something in the conversation: ask another person to act.
Contrast ‘The window is closed.’ This typically reports a state of affairs. The same broad subject matter—a window—does not imply the same speech act. Ask the practical question, ‘What action is the speaker trying to perform with these words?’
A simple worksheet can record the words spoken, the likely act, the intended recipient and the evidence for that interpretation. This is a starting analysis, not a guarantee that the speaker’s inner intentions are observable.
2. Why the theory belongs in vocabulary
Traditional word lists help a student recognise and recall expressions. Speech-act vocabulary adds an action layer: request, offer, refuse, promise, warn, report and authorise name different things people can do with language.
The Stanford Encyclopedia of Philosophy guide to Speech Acts explains the historical argument that people use utterances to perform actions beyond representing truth. These ideas have influenced philosophy, pragmatics, linguistics and applied analysis.
For learners, the point is not memorising a taxonomy. It is being able to identify what a particular message commits anyone to and what response would make sense next.
3. Words, force and outcome are three different things
J. L. Austin’s classic analysis distinguishes aspects often called locutionary, illocutionary and perlocutionary. The locutionary level concerns what is said; illocutionary force concerns the action performed in saying it; perlocutionary consequences concern effects produced by speaking.
If someone says ‘Be careful of the wet floor’, the words describe or indicate a danger and may perform a warning. The listener may become cautious, ignore the advice or misunderstand the location. The resulting behaviour is a distinct question.
Do not report that a warning succeeded simply because a warning was uttered. The occurrence of an act and its practical effect can diverge.
4. Locution: what words were actually used?
A fictional instruction reads, ‘The corrected file is on the class folder.’ Before inferring anything about the speaker’s intention, identify the content, the grammatical relations and the possible referents.
Which file is corrected? Which folder is intended? The literal description may be incomplete for the recipient even if its words are grammatical.
Accurate transcription and interpretation matter because a mistake at this stage changes the basis for deciding which speech act was performed. Reconstruct the words faithfully before analysing what the speaker meant to do.
5. Illocution: what is the speaker doing?
The same utterance can have different forces. ‘The door is still open’ may be an observation to one listener, a complaint in a cold room, or an indirect request to close it when addressed to someone by the door.
The force depends on the setting and shared expectations. The words alone do not provide a universal label.
Ask for contextual clues: who speaks, to whom, what activity is underway and how the next turn responds. If several interpretations remain plausible, record the ambiguity rather than invent one certain intention.
6. Perlocution: what effect followed?
A warning may frighten someone, persuade them to change direction, or have no observed effect. These are potential consequences, not simply different spellings of the warning itself.
A teacher who says ‘Please check the units’ has made a request or instructional prompt. Whether the learner checks them correctly is a performance question requiring observation of the next action.
This distinction protects accurate progress reporting. A message sent, a message understood and a task completed should not be entered as the same event.
7. Direct speech acts and grammatical form
‘Close the notebook’ is conventionally an imperative that can perform a directive. ‘Did you close the notebook?’ is interrogative and commonly asks for information about the event.
Grammatical form offers an important clue, but actual acts depend on use. An imperative can be a gentle instruction, a command or part of a quoted example. An interrogative can be used for more than asking a literal yes-or-no question.
Identify the ordinary form first, then inspect its function. A student should not infer that every question mark means the speaker genuinely wants a factual answer.
8. Indirect requests
‘Could you lower the volume?’ is grammatically a question about ability but usually functions as a polite request in everyday conversation.
A literal answer ‘Yes, I could’ might address the grammatical question without responding to the intended practical action. When the context is unclear, the listener may legitimately clarify.
Teach learners to consider both the surface meaning and the intended action. This makes reading dialogue and responding to ordinary instructions more reliable.
9. Request versus order
‘Would you mind moving the chair?’ commonly functions as a request. ‘Move the chair now’ may carry stronger directive force, especially when spoken by someone with relevant authority.
Tone, roles, urgency and established rules matter. A student cannot determine the full force of an utterance from the presence or absence of please alone.
For an English exercise, write a realistic context for each utterance. Ask whether the listener may decline, what authority applies and what the speaker is expecting.
10. An order does not become legitimate just by being phrased strongly
A fictional pupil says to a classmate, ‘I order you to change the marks.’ The verb order does not give the pupil legitimate authority over assessment records.
A speech-act analysis should separate the act someone attempts to perform from whether its necessary institutional conditions are satisfied.
Do not teach learners that confident language creates authorisation. Check the real procedure and the person entitled to make a consequential decision.
11. Promise versus prediction
‘I will return the book on Friday’ may be a prediction, statement of intention or promise, depending on context. ‘I promise to return the book’ makes the undertaking more explicit.
A promise ordinarily involves a commitment by the speaker to a future action and relevant conditions of sincerity and social convention. The Stanford Encyclopedia of Philosophy entry on Promises reviews the relationship with speech-act theory.
Students should not treat every future-tense sentence as a binding promise. Ask what the speaker undertook, to whom, under what circumstances and with what legitimate understanding.
12. The words I promise do not guarantee sincerity
A student can utter ‘I promise’ insincerely or without the intention to carry out the proposed action. The phrase makes a commitment explicit but does not allow an observer to read the speaker’s mind.
People may evaluate promises using later conduct and relevant evidence. The original utterance and the eventual fulfilment remain distinct.
Use an invented low-stakes example, such as returning a borrowed classroom book. Avoid teaching that saying a formula can establish every legal or moral consequence by itself.
13. Offer versus acceptance
‘Would you like to use my spare ruler?’ makes an offer in an ordinary classroom context. The listener can accept, decline or ask for clarification.
The offer does not prove that the ruler has already been transferred. Acceptance may establish a new interactional expectation, but the practical handover remains another event.
This distinction is helpful when reading narratives: a character’s offer, another character’s response and the resulting action should not be merged into one unobserved event.
14. Invitation versus announcement
‘We are meeting after school’ may announce a planned activity. ‘Would you like to join us after school?’ invites the recipient to participate.
The two expressions can concern the same event but generate different next responses. An invitation can be accepted or declined; an announcement might need acknowledgement or a factual check.
Ask the learner to write one fitting reply to each act and explain what the reply treats as relevant.
15. Advice versus requirement
‘You should practise these examples’ may be advice, guidance or an obligation depending on the source and institutional context. ‘You must submit them by Friday’ more explicitly states a requirement in ordinary task language.
The difference matters when a parent plans a child’s work. A recommendation can be valuable without being compulsory, and a requirement can be invalid if misreported or issued without authority.
See Semantic Features for the contrast between required, recommended and optional.
16. A warning is different from a threat
‘The path is slippery’ may function as a warning about a condition. ‘Do this or I will harm you’ can function as a threat. Their interpersonal roles and legitimacy differ even if both refer to an unwanted future event.
Not every unwanted prediction is a threat. Distinguish the relevant evidence, speaker’s agency and intended action, and avoid inferring a person’s motives from a fragment without context.
The aim is to identify the communicative function accurately, not make allegations from ambiguous wording.
17. Apology versus explanation
‘I am sorry for sending the wrong file’ can perform an apology. ‘I sent the old file because I misunderstood the version label’ provides an explanation. A speaker may combine both acts.
Explaining why an error occurred is not automatically the same as accepting responsibility, and apologising does not itself correct the practical problem.
A useful handover adds a remedy: identify the correct version and send it through the agreed channel. Vocabulary can separate social repair from technical correction.
18. Complaint and request can overlap
‘There is too much noise in this room’ might report a fact, express dissatisfaction or indirectly request that someone lower the volume. The intended act depends on context.
One utterance can be treated as doing more than one thing at once. A listener may respond by acknowledging the problem and offering a remedy.
Instead of assigning a single forced label to every sentence, ask which next action the participants make relevant in the particular interaction.
19. A statement can be true but pragmatically misplaced
A student answers ‘Two plus two equals four’ when asked where an assignment was uploaded. The mathematical statement is true but does not perform the expected responsive act.
Meaningful communication depends partly on what the current conversation needs. Truth alone does not establish relevance to the question.
The Discourse Marker and Common Ground guides develop related tools for following the interaction.
20. Performative expressions
Some utterances name the act being performed: ‘I apologise’, ‘I promise’ or, under appropriate procedures, ‘I declare the meeting open’. These are familiar examples of explicit performative wording.
Austin’s work showed that some acts are evaluated by whether their conventions and circumstances are appropriate, not only by truth or falsity.
Merely printing a performative sentence on a worksheet does not make the described institutional change occur. Quoting and performing an expression are different activities.
21. Authority and institutional declarations
An authorised organiser may announce a scheduled event cancelled through a recognised process. A random observer saying ‘The event is cancelled’ need not have the power to make it so.
The speech-act distinction asks what action is attempted, who can perform it and what conditions apply. These rules come from the actual institution or task.
The Stanford Speech Acts entry uses appointment and opening proceedings among examples requiring an appropriate authority. Our fictional scenarios do not create real legal or administrative powers.
22. Felicity conditions: what makes an act appropriate?
An act may depend on the right people, circumstances, intention or conventions. Promising an impossible action or issuing an order without relevant authority raises questions about the success or appropriateness of the attempted act.
Philosophers use felicity conditions to analyse when acts are successfully performed and when they misfire or are abused. The details differ across kinds of acts and theoretical accounts.
For an everyday task, ask three questions: Is the speaker entitled to do this? Is the proposed action clear? Are the relevant conditions and recipient established?
23. Saying versus quoting
A teacher writes ‘I hereby open the meeting’ on a grammar worksheet. The words are being quoted or used as an example, not used to begin the teacher’s actual meeting.
Quotation context changes how the sentence functions. This matters when readers encounter a promise in a story or a command within a hypothetical dialogue.
Have learners distinguish the narrator’s statement about an utterance from the act performed by the fictional speaker inside the scene.
24. Intent is not identical to uptake
A speaker may intend to invite someone to a study session, but the listener may hear only a factual description of a timetable. The act intended and the response received can diverge.
Theoretical accounts differ on exactly which recognition or uptake conditions are required for some speech acts. A classroom guide should not declare that every misunderstanding completely nullifies the speaker’s act.
Practically, check whether the intended recipient understood the relevant commitment or next action. A clarification request can be more useful than assuming successful communication.
25. A speech act can be misunderstood
A student says ‘I can help after lunch’ intending an offer. The recipient interprets it as a firm promise to complete the entire project alone.
The reply ‘Do you mean you are available to review one section or that you will take the whole task?’ repairs the difference in intended commitment.
Read Conversational Repair for ways to identify and resolve this kind of action misunderstanding.
26. Promises and permissions need different replies
An organiser says ‘You may use the room after three.’ That can communicate permission under the local rules. It does not necessarily promise that every desired piece of equipment will be available.
A student replies ‘Thank you, I will check the room booking.’ This acknowledges the permission while reserving the practical check.
Distinguish allowed, available, required and promised. Each term changes the listener’s justified next action.
27. What silence does and does not do
A group proposes a change to the draft and receives no reply. Silence may be interpreted differently across settings; it is not automatically an agreement.
If the project requires explicit approval, a lack of response leaves that condition unresolved. If a specific legitimate procedure defines another default, use that rule rather than a personal assumption.
Treat shared work with appropriate clarity: ‘The revision is awaiting approval’ is often safer than ‘Everyone agreed’ when nobody responded.
28. Indirect refusals are possible
An invitation receives the reply ‘I have a lesson at that time.’ The listener may understand this as a reason for declining, even though the word no is absent.
The speaker could also be inviting a discussion about a different time. We should not claim that one indirect phrase always performs the same act.
A useful practice task asks what response the first speaker might offer, such as ‘Would another time work?’ This tests the function without forcing the class to guess invisible intentions as facts.
29. Different languages may realise acts differently
Languages and communities have different conventions for politeness, directness, greetings and the formulation of requests. One-to-one translation of grammatical form may not preserve the intended act.
A translator should identify the actual request, apology, offer or permission and express it naturally in the target situation. Formality and social relationships may require care.
Do not reduce communities to stereotypes such as ‘people from this language are indirect’. Interactional norms are varied and depend on context and individual participants.
30. Digital buttons can encode intended acts
A button labelled Submit asks the system to perform an operation. A button labelled Request Approval initiates another workflow. Their labels should match the actual action and possible response.
Pressing Submit does not prove that the record was received. An acknowledgement, completion message or current state may need separate checking.
The State Transition guide distinguishes attempted actions, events and confirmed outcomes.
31. A notification is not the same as approval
‘Your request has been received’ performs an acknowledgement of receipt in an appropriate system. ‘Your request has been approved’ makes a different claim about the recorded decision.
A learner may mistakenly treat the former as permission to proceed. The vocabulary difference is operational, not cosmetic.
Ask what state the recipient is in after each message and what further evidence is needed before the next step.
32. English comprehension: identify what the character does by speaking
In an invented story, Mira says, ‘I will keep your place while you ask the librarian.’ The reader must decide whether the line is merely a prediction or a commitment to help in that conversation.
Details about the relationship, response and subsequent action may support an interpretation. A strong answer distinguishes the spoken undertaking from its later fulfilment.
Do not add an unseen internal motive when the question only asks what speech act is performed. Use the line and context as evidence.
33. English writing: select an act that fits the purpose
A student writing a polite request to borrow a resource needs a specific action and an identifiable recipient. ‘I would appreciate your assistance’ is courteous but may not tell the reader what is requested.
A stronger message says ‘Could I borrow the science model for our Tuesday lesson? I will return it afterward.’ The addressee now knows the object, date and intended act.
Useful vocabulary supports a clear real request rather than merely making the sentence sound more formal.
34. Science writing: statements versus instructions
‘The solution was heated’ reports a step that the writer claims occurred. ‘Heat the solution’ instructs a reader to perform an action. Mixing these acts can confuse a report with a procedure.
Actual science practicals involve safety requirements and supervision not supplied by this fictional language example. Follow the authorised task and protocols rather than treating a classroom rewrite as permission to conduct an experiment.
Ask students whether the text aims to describe past observations, communicate a safe approved procedure or explain a scientific relationship.
35. Mathematics: assumptions and commands
‘Let x represent the number of notebooks’ establishes a local variable convention for a problem. ‘Find x’ instructs the learner to calculate it. ‘Therefore x=5’ asserts a mathematical consequence.
The same lesson contains several communicative actions. Each has different standards: a definition must be clear, a directive must specify the task, and an inference must be justified.
Analysing their functions helps readers understand why a complete solution includes more than a final number.
36. A project handover: request, acceptance, confirmation
An invented group asks Kai to review the script. Kai replies ‘Yes, I can review the introduction tonight.’ The acceptance is limited to a particular section and time.
Another member should not report ‘Kai has approved the full script’. The request, acceptance of work and approval decision are separate acts.
A short status record can identify who accepted which task and what still requires review. This prevents a promise to try from being converted into a reported outcome.
37. Worked case: a false approval chain
An editor sends a draft to the reviewer with ‘Can you check the sources?’ The reviewer replies ‘Received.’ The editor records ‘Sources approved’ and publishes the draft. The error lies in interpreting acknowledgement as evaluation.
Rewrite the exchange to include distinct acts: request review; acknowledge receipt; report findings; issue explicit approval when authorised. If the reviewer discovers a missing source, the status must remain unresolved or changes requested.
Have learners identify which sentence performed each act and which imagined conclusion was not supported. The mistake is not fixed by adding the word please; it requires accurate action labels.
38. Worked case: a polite sentence with two functions
A tutor says to a student, ‘Would you show your working?’ Grammatically this resembles a question about willingness, but in context it may perform a request to display or explain the steps.
The tutor may also be checking whether the student understands the method. The learner can answer by providing the work or asking what part should be shown.
A thoughtful reading recognises plausible overlapping purposes without treating either as certain without context.
39. Worked case: apology versus remedy
A student uploads the wrong report and writes, ‘Sorry for the mistake.’ The message performs an apology in context but does not complete the required correction.
A fuller response identifies the error, sends the correct file where permitted and confirms the current status. The social act and the task repair are related but different.
The lesson is to preserve the role of courtesy while ensuring it does not conceal the missing practical action.
40. A practical five-question speech-act check
Write five headings: Words; Intended Act; Relevant Roles; Required Conditions; Observed Response. Use them with a short invented dialogue before attempting a complex real example.
For ‘Could you review page two?’, the likely act is a request. The recipient needs access to the page and enough information about the requested review. The observed response might accept, decline, ask for clarification or perform another action.
Do not enter intended completion under Observed Response. The form is an aid to separating speech from effect, not a licence to infer someone else’s understanding.
41. Diagnostic: identify the action and the limit
Case A: ‘The session starts at four’ may be an announcement; verify the current timetable if action depends on it. Case B: ‘I promise to return it’ undertakes a future commitment if used appropriately; fulfilment remains a later question.
Case C: ‘Do not enter’ may communicate a prohibition under relevant authority; its legitimacy depends on context. Case D: ‘That room is noisy’ may be a report, complaint or indirect request; more context is needed.
Case E: ‘Received, thanks’ acknowledges a message without certifying that the work was reviewed. Ask which additional act the listener still needs.
42. Twelve practice questions with short answers
1. Does every sentence merely describe facts? No. 2. Can a question function as a request? Yes. 3. Is a promise the same as a prediction? Not necessarily. 4. Does uttering a warning guarantee that someone takes precautions? No.
5. Is grammatical form always sufficient to identify the act? No. 6. Can an apology coexist with an explanation? Yes. 7. Does authority matter for institutional declarations? Yes. 8. Is quoting an order the same as issuing it? No.
9. Does ‘received’ entail ‘approved’? No. 10. Can one utterance have several plausible functions? Yes. 11. Can a misunderstanding be repaired? Often through clarification. 12. What is the central question? What action does this utterance perform in this context?
43. Frequently asked questions
Is a speech act always spoken? Written messages can perform many communicative acts too. Is speech-act theory just etiquette? No. It concerns linguistic actions, commitments, conventions and effects. Do words themselves create authority? No.
Can a child use the idea? Yes, through familiar contrasts such as ask, promise, warn and tell. Does a speech act have to succeed? Different notions of success include performing the act under its conditions, recognition and later effects; these should be distinguished.
Why is it a vocabulary technology? Knowing the action associated with an utterance helps people select the right reply, verify commitments and coordinate work.
44. Research, limitations and what to practise next
Primary references: Stanford Encyclopedia of Philosophy, Speech Acts; John Langshaw Austin; Pragmatics; and Promises. They establish the theoretical distinctions; they do not report outcomes for the fictional eduKate teaching cases above.
Austin, Searle and later theorists differ on particular definitions and the role of intentions, conventions and uptake. This guide uses the concepts to ask better questions, not to settle every philosophical disagreement or supply legal advice.
Choose three messages you encounter today. For each, identify the likely act, the relevant participant, one condition for its legitimate performance and the reply it makes appropriate. If the exercise prevents even one confusion between a request and an approval, the vocabulary has become an action tool.
