Hello, AngloPassers, how are you today?

Now, you probably didn’t stop to think about the grammar in that question. You didn’t analyse how how connects to are, or how are connects to you. You recognised the whole phrase immediately and understood it without effort.

That is because Hello, how are you today? is not processed as separate words but as one familiar unit of language. Linguists call this kind of unit a chunk. In simple terms, a chunk is a group of words that speakers store and use together as one piece. We do not rebuild these phrases each time we use them. We recognise them, understand them, and produce them as a whole.

Chunks can be everyday expressions, such as on my way or by the way. They can also be longer sentence patterns, such as it is widely believed that…. Although these chunks look different, they work in the same way. They are familiar patterns that help speakers and writers communicate clearly and efficiently.

This is how fluent English works. Instead of building sentences word by word, we combine known patterns and create meaning chunk by chunk.

Where the Idea of Chunks Comes From?

The idea of using language in chunks comes from corpus linguistics, a field that studies large collections of real English texts. One of its key figures was Professor John McHardy Sinclair (1933–2007), whose analysis of real language data first showed that people rely on these fixed and familiar patterns rather than creating new sentences from scratch each time. He called this the idiom principle.

These findings later influenced language teaching, and in the 1990s, Michael Lewis developed them into a practical approach for the classroom, focusing on teaching chunks to help students think in patterns instead of rules. He found it an effective way of helping students get past the 'intermediate plateau' and move towards advanced English.

Why this Matters for IELTS Writing?

This is especially important for IELTS Writing. Most IELTS candidates lose marks in Writing Task 2 even when their grammar is mostly correct. Their sentences often sound slow, unnatural, or unclear because they are being built one word at a time under exam pressure.

Examiners penalise this because IELTS writing is not only about accuracy. It is about clarity, control, and organisation. This is why many candidates with good ideas remain stuck at Band 6 or 6.5.

If your score is stuck at Band 6 or 6.5, the problem is often not your ideas and not your grammar knowledge. The problem is that you are trying to invent sentences during the exam instead of relying on familiar language patterns.

How AngloPass Applies this Idea?

At AngloPass, this principle sits at the centre of our Copy → Practise → Create method. In the Copy stage, you notice useful IELTS language and write it down. This helps your brain recognise the patterns that appear again and again in high-scoring writing. In the Practise stage, you reuse these patterns many times. You keep the structure, but change the key ideas. With repetition, the language becomes faster and more automatic. In the Create stage, you combine the chunks you have learned with new topics and your own opinions.

At this point, you are beginning to use familiar patterns flexibly and confidently,

and many students say this is the point where writing starts to feel easier. IELTS introductions, topic sentences, and conclusions stop feeling confusing and start to feel manageable.

With regular practice, your writing becomes clearer, more natural, and better organised. This is exactly what IELTS examiners are trained to reward.

Final Thought and Next Step

Fluent IELTS writing isn’t built in one jump. It’s built chunk by chunk, through repeated, focused practice. If you’re serious about moving beyond Band 6 or 6.5, the next step is simple: start collecting the right chunks and start using them properly.
