What is the informative function of language?
The informative function of language is the use of words to share information: facts, ideas, descriptions, explanations, and reports. When you say “The train leaves at nine,” you are using language mainly to tell someone something about the world.
Informative language is often described as language that can, at least in principle, be judged true or false. “Water boils at a lower temperature at high altitude” is a claim that can be checked. That is a useful rule of thumb, though not a perfect one. A sentence can be informative and still be wrong, uncertain, or a matter of opinion.
Informative language is usually discussed alongside two other common uses of language:
- Informative: to report or explain something.
- Expressive: to show feelings or attitudes.
- Directive: to get someone to do (or not do) something.
Informative examples in everyday sentences
Here are plain examples of the informative function. Each one mainly tells the listener or reader something.
- The library opens at 9 a.m. on weekdays.
- My sister lives in Toronto.
- Bees collect nectar from flowers.
- The meeting has been moved to Thursday.
- The bus was late because of road works.
- Tigers have stripes.
- The recipe uses three eggs and a cup of flour.
- She works as a nurse at the local hospital.
- The museum is closed on Mondays.
- The report says that sales rose in the second quarter.
None of these sentences asks for anything or mainly shows emotion. They give information, and a listener could ask, “Is that so?”
Informative language in different kinds of writing
Some text types lean heavily on the informative function. Typical examples include:
- News reports: “Two roads were closed after heavy rain on Tuesday.”
- Textbooks and encyclopedias: “Photosynthesis is the process by which plants make food using light.”
- Scientific and technical reports: “The sample was heated for ten minutes.”
- Summaries: “In the novel, a young woman moves to the city and takes a job at a newspaper.”
- Timetables, notices, and labels: “Contains nuts. Store in a cool place.”
- Everyday speech: “I got home around six.”
Writers of these texts usually aim to be clear and accurate (the first of our rules of writing), and they tend to avoid strong emotion or persuasion.
Can informative language be a question or a command?
Most informative sentences are declarative statements, but the function is about purpose, not just sentence form. Some sources point out that questions can also carry information when the speaker is not really asking for an answer. For example, “Isn’t it Wednesday?” can remind someone of a fact they already know. In that case the question is doing informative work.
In the same way, a sentence that looks informative can be directive. “The door is open” may simply report the state of the door, or it may be a hint to close it. Context decides.
Informative vs expressive vs directive language
| Function | Main purpose | Example |
|---|---|---|
| Informative | Share facts or ideas | “The film starts at 7:30.” |
| Expressive | Show feelings or attitudes | “What a wonderful evening!” |
| Directive | Get someone to act | “Please turn off your phones.” |
Poetry and personal writing often lean expressive. Recipes, manuals, and signs often lean directive. News reports and textbooks lean informative.
How to identify the informative function in a passage
Ask these questions about a sentence or passage:
- Is the main point to tell me something? If yes, it is likely informative.
- Could it be checked, or argued to be right or wrong? If so, that points toward informative.
- Is the writer mainly showing a feeling? If so, it is probably expressive instead.
- Is the writer trying to make me do something? If so, it is probably directive.
- Does the sentence do more than one job? Many do, and that is fine.
Compare these three sentences:
- “The pool closes at six.” (informative)
- “I love swimming here!” (expressive)
- “Please leave the pool before six.” (directive)

How many functions of language are there?
There is no single fixed number. Many introductory courses teach three (informative, expressive, directive). Other models list more. The linguist Roman Jakobson, for example, described six functions of communication: referential, emotive, conative, phatic, metalingual, and poetic. In that model, the referential function is close to what is called informative here.
Lists of “five functions” or “ten examples” found online often vary by source, so it helps to check which model a class or exam uses. A commonly taught extended list adds uses such as social or relationship-building talk (greetings, small talk) and ceremonial or performative speech (for example, “I now pronounce you married”).
Mixed functions in real communication
Real speech and writing rarely stick to one function. A charity letter might explain what a disease is (informative), tell a moving story (expressive), and then ask for a donation (directive). A weather forecast mostly informs, but a phrase like “Don’t forget your umbrella” adds a directive.
When you analyze a text, it usually helps to decide which function is dominant in each sentence or paragraph rather than looking for a single label for the whole text.
A related example of mixed functions is wording that makes an offer. Our page of offer examples in sentences shows informative and directive language working together.
Frequently asked questions
What is the informative function of language?
It is the use of language to communicate information, such as facts, descriptions, explanations, or reports.
Can you give some examples of informative communication?
Examples include a news report, a science textbook, a train timetable, and a sentence such as “The store closes at eight.”
Do informative statements have to be true?
No. An informative statement claims something about the world, and it may turn out to be true or false. The label describes the purpose of the sentence, not its accuracy.
Is informative language always formal?
No. Everyday remarks like “It’s raining” are informative too. Formal tone is common in reports and textbooks but is not required.
