One of the things that separates top-band IGCSE English Language writing from average writing is the ability to adapt register — to write in the right tone, vocabulary, and style for the specific audience and purpose the question asks for. A letter to a local council is different from a speech to Year 9 students is different from an article for a travel magazine. Here’s how to do it well.
What Is Register?
Register refers to the variety of language appropriate to a particular situation — formal or informal, technical or accessible, authoritative or personal, distant or intimate. It’s shaped by who you’re writing to, what you’re trying to achieve, and where the writing will appear. Getting register right is a sign of real linguistic awareness; getting it wrong — being too formal for a friendly article, too casual for a professional letter — signals a failure to read the task.
Read the Audience Clue in the Question
IGCSE directed writing questions always specify an audience. “Write a speech for your school’s Year 10 assembly.” “Write a letter to the editor of a local newspaper.” “Write an article for a magazine aimed at parents of young children.” Each of these implies a different register — and your job is to identify and maintain it consistently.
Ask yourself: How old is my audience? What do they already know about this topic? What is their relationship to me as the writer? What do they expect from this kind of writing? The answers shape everything from vocabulary level to sentence structure to tone.
Signals of Register
- Formality: Contractions (“don’t”, “it’s”) signal informality; full forms signal formality. Colloquial vocabulary signals informality; Latinate vocabulary signals formality.
- Address: “Dear Sir/Madam” vs “Hi everyone” vs “Ladies and gentlemen” — each places the relationship immediately.
- Sentence structure: Formal writing tends towards longer, more complex sentences; informal writing uses shorter, more conversational structures.
- Use of humour: Appropriate in some registers (a light feature article), inappropriate in others (a formal complaint letter).
Consistency Is the Key
The most common register mistake is inconsistency — starting formally and drifting informal, or mixing tones in a way that feels jarring. Once you’ve established a register, maintain it throughout. A speech to Year 10 students can be warm and engaging, but it shouldn’t suddenly become as casual as a text message. A formal letter can make a pointed argument, but it shouldn’t adopt the register of an opinion column.
Register, audience awareness, and directed writing technique are practised in every Thorogood English IGCSE English Language session. Join the waiting list for January 2027.
