When words do things — Language, 14–17 years
Some utterances do more than convey information: they promise, order, apologise or name something. Speech-act theory helps us notice the action performed through language.
An utterance can be an action
When someone says “I apologise”, the words are not merely reporting an apology: saying them is the apology. “Please close the window” asks for an action, while “I promise” creates a commitment. Meaning includes what the speaker is doing.
The problem of hidden actions
If we treat every sentence as information, we miss why words can change relationships, permissions and duties. Philosophers studied speech acts because “The meeting is open” can announce a fact, while “I declare the meeting open” performs an official act.
A promise, step by step
Take the sentence “I’ll send you the notes tonight.” First, its words describe a future action. Second, the speaker presents that action as their responsibility. Third, saying it to the listener creates an expectation. If the speaker is joking, lacks control or is quoting someone else, the promise may not count.
The trap: looking only at grammar
A reasonable mistake is to label “Can you pass the salt?” as a question because it has question grammar. Literally, it asks about ability; in an ordinary meal, it functions as a polite request. Grammar gives clues, but situation and purpose decide the act.
Promises, permissions and warnings
Speech acts matter in school rules, contracts, interviews and online messages. “You may enter”, “I accept the terms” and “Watch out!” do different social jobs, even when they are short. Noticing the job helps you judge whether a statement gives permission, creates a duty or warns you.
