IB DP Language B – Conceptual understanding: audience, context, purpose, meaning and variation Study Guide

This study guide teaches the five conceptual understandings of IB Diploma Programme Language B: context, audience, purpose, meaning and variation. It is aligned to the IB Diploma Programme Subject Brief: Language B, first assessment 2020, which names these five in its curriculum model, and it applies them to reading and writing tasks set in three prescribed themes: human ingenuity, social organization and sharing the planet. The concepts are the same at SL and HL; HL asks you to use them with more complex language. It follows the IB Language B subject brief for first assessment 2020, which remains the examined course until the new syllabus is first assessed in May 2029, so it applies to the 2026, 2027 and 2028 sessions.

Use it with the conceptual understanding revision notes for quick recall and the conceptual understanding practice questions for original passages with worked answers. For the whole course, see the Language B course hub, the printable checklist, the syllabus guide, the subject guide, the exam preparation page and the assessment revision notes. Theme pages: Identities and Sharing the planet.

This page is in English and so are the model texts. Each section ends with what to check in your target language.

What this unit covers

Part of the brief	What you must be able to do	SL/HL
Context	Say where, when and in what medium a text is made and read, and how that shapes it	Both
Audience	Identify who a text is for and the relationship between writer and reader	Both
Purpose	Say why a text was written, and spot a second purpose behind the first	Both
Meaning	Explain what a text says directly and what it implies	Both
Variation	Recognise and produce different registers, tones and varieties of the language	Both
Complexity	Handle the same concepts with more complex language and structures in Paper 1	HL demands more

The brief says students become effective communicators “by considering the conceptual understandings of context, audience, purpose, meaning and variation”. Two assessment objectives point the same way: communicate “in a range of contexts and for a variety of purposes”, and use language “appropriate to a range of interpersonal and/or intercultural contexts and audiences”. So these concepts are not a separate topic. They are how every text you read or write is judged.

The five concepts

Context

Context is the situation around a text: where it appears, when, in what medium (a printed leaflet, a post, a speech) and in what culture. A notice on a noticeboard and a message in a group chat can carry the same news, but the context changes the layout, length and language.

When reading, ask: where would I find this text? What event or problem prompted it? When writing: fix the setting from the task before you start.

Audience

Audience is who the text is for and what the writer–reader relationship is: friend, stranger, official, a whole community. The audience decides how much you explain and how formally you write.

Ask: does the reader know the writer? Are they older, younger, in authority? What do they already know?

Purpose

Purpose is why the text exists: to inform, persuade, instruct, request, complain, thank, entertain or reflect. Many texts have two. A council leaflet about recycling informs, but it also wants to change behaviour.

Ask: what does the writer want the reader to know, feel or do after reading?

Meaning

Meaning is what a text communicates. Some is explicit: stated in words. Some is implicit: suggested by word choice, tone or what is left out. “Residents are reminded that bins must be inside by 8 p.m.” states a rule; the word “reminded” implies that some people have been breaking it.

Ask: what is said, and what is suggested? Which words carry the suggestion?

Variation

Variation is the way language changes with the other four concepts. It includes:

• Register: how formal the language is.
• Tone: the attitude the text shows (warm, urgent, ironic, apologetic).
• Medium: spoken language is usually looser than written; a text message is shorter than a letter.
• Regional variety: the same language differs between countries and regions in vocabulary, pronunciation and some grammar.

Target language check. Find out how your language marks formality. Many languages have a formal and an informal “you” (French tu/vous, Spanish tú/usted, German du/Sie). Some, such as Japanese and Korean, have whole levels of polite verb forms. Spanish shows regional variation too: vosotros is used for informal plural “you” in most of Spain, while Latin American Spanish uses ustedes for both formal and informal plural. Learn the forms your course uses and apply them consistently.

Register and tone

Register and tone are not the same thing. Register is how formal; tone is what attitude. A formal letter can be angry, grateful or cold; a text message can be cheerful or annoyed.

Register	Typical audience	Features in English	What to check in your target language
Formal	Officials, strangers, the public	Full sentences, no contractions, impersonal forms (“It has been decided”), precise vocabulary	Formal “you”, polite verb forms, set openings and closings
Semi-formal	Teachers, readers of a school magazine, a club	Clear structure, some direct address, few contractions, no slang	Which forms of address are acceptable for a teacher or editor
Informal	Friends, family, peers online	Contractions, questions, exclamations, fragments, humour	Informal “you”, everyday vocabulary, common abbreviations

Tone words worth learning in your target language: urgent, reassuring, enthusiastic, critical, sympathetic, humorous, ironic, neutral. Tone comes from choices you can point to: intensifiers (“absolutely”), modal verbs (“must” vs “could”), punctuation, and the balance of facts and feelings.

Worked example 1: reading a text through the five concepts

Original text written for Marlbridge:

NOTICE TO RESIDENTS: Riverside Road

From Monday 3 March, Riverside Road will be closed to motor vehicles between 7 a.m. and 7 p.m. on weekdays. This trial will last twelve weeks. Its aim is to reduce air pollution near the primary school and to make the route safer for cyclists. Residents who require vehicle access for medical reasons should contact the Transport Office. Your views are welcome and will be considered before any permanent decision is made.

Step 1: context. A printed notice from a local authority, before a change to a road. Theme: sharing the planet (the environment) and social organization (rules in a community).

Step 2: audience. People who live on or use the road. The writer is an authority; the readers have no personal link to it.

Step 3: purpose. Mainly to inform (“will be closed”, dates, times). Second purposes: to justify (“Its aim is to reduce air pollution”) and to reassure (“Your views are welcome”).

Step 4: meaning. Explicitly, a road closes for twelve weeks. Implicitly, “trial” and “before any permanent decision” suggest the closure may become permanent, and the authority expects objections.

Step 5: variation. Formal register: no contractions, passive forms (“will be closed”, “will be considered”), the impersonal “Residents who require”. Tone: neutral but careful, with no emotional words.

A weak answer says “The text is formal.” A strong answer says what makes it formal and why that suits the audience: an authority speaking to the whole public avoids personal language so the rule sounds fair.

Target language check. Find how your language makes impersonal or passive statements (a reflexive, an impersonal pronoun, a passive), and which is most natural in official notices.

Worked example 2: one message, three audiences

Human ingenuity. Your class has built a solar-powered phone-charging bench for the school yard. You need to tell three audiences.

To the head of school (formal email, purpose: request). “Dear Ms Rahman, I am writing on behalf of Class 12B to ask whether we may install the charging bench we have designed in the main courtyard. We would be grateful for a meeting to discuss safety checks.”

To the school magazine (semi-formal article, purpose: inform and interest). “Ever run out of battery before the bus home? Class 12B thinks it has the answer: a bench that turns sunlight into free charging.”

To a friend (text message, purpose: share news). “Bench is DONE!! Head says yes if it passes the safety check. Come see it tomorrow?”

What changes, and why:

Feature	Email	Article	Message
Opening	Formal greeting and title	Question to hook readers	None
Sentences	Complete, polite conditionals (“We would be grateful”)	Mix of question and statement	Fragments, exclamations
Vocabulary	“install”, “discuss”, “safety checks”	“the answer”, “free charging”	“DONE”, “come see”
Relationship	Pupil to authority	Writer to peers	Friend to friend

The content barely changes; register, tone and structure all move. That is variation in action, and it is what the assessment objectives mean by language appropriate to contexts and audiences.

Target language check. Rewrite each version with the correct form of “you” (formal singular for the head, plural or general for magazine readers, informal for the friend) and the polite forms for requests.

Worked example 3: decoding a writing task

Original task written for Marlbridge: “Your town plans to replace its weekly street market with a large supermarket. Write a text for your local newspaper’s letters page giving your view.”

Before planning content, extract the concepts:

• Context: a letters page in a local newspaper; a public debate about social organization and community life.
• Audience: the newspaper’s readers (adults, local, many undecided) and, indirectly, the town council.
• Purpose: to persuade, and to show you understand the other side.
• Text type: a letter to the editor: formal opening and closing, a clear position early, reasons with examples.
• Register and tone: formal; firm but polite. Sarcasm would weaken your case with undecided readers.

Only then write the points: small traders and local jobs; the market as a meeting place for older residents; the counterpoint that a supermarket offers longer opening hours and lower prices.

At HL, Paper 1 tasks require more complex language and structures and demand higher-order thinking, and the word range is higher. That means weighing arguments with concessions (“Although the supermarket would…, it would also…”) and precise, varied vocabulary. At SL, aim first for accuracy and a clear match between register and audience.

Using the concepts in Paper 2 and the oral

Paper 2 (receptive skills). Reading carries 40 marks and listening 25, each 25% of the course. Whatever a question asks, you read faster when you fix the text type, audience and purpose first. In listening, register is often audible: a radio interview sounds different from two friends talking. Tone words such as “surprised”, “doubtful” and “relieved” often decide an answer.

Individual oral (25%). At SL the stimulus is a visual image clearly relevant to one or more themes; at HL it is an excerpt from one of the two literary works studied. Treat the stimulus as a text: who made it, for whom, and why? A poster for a clean-up day has an audience and a purpose; a literary excerpt has a narrator, a reader and a tone. Saying so moves you from describing to interpreting.

Your teacher will share the assessment criteria and formats for each component. This page does not guess at them.

Common errors

• Naming the register (“formal”) without the features that show it.
• Mixing registers: a formal letter that ends “See ya”, or an informal blog full of impersonal passives.
• Switching between the formal and informal “you” in one text.
• Confusing tone with register: calling an angry formal complaint “informal”.
• Giving “everyone” as the audience when the text clearly targets a group (parents, cyclists, young voters).
• Stopping at the first purpose and missing the second (a notice that informs and also defends a decision).
• Treating implied meaning as fact: write “this suggests” or “this implies” for anything not stated.

Next, test yourself with the revision notes and try the practice questions.
