I was sitting in my office last Tuesday, staring at a pile of Cambridge exam scripts, when I saw it again: another student losing a full mark because they treated a complex structure like a math equation instead of a tool for emphasis. Most textbooks will give you a dry, twenty-page lecture on the mechanics of grammar, but they completely fail to explain how cleft sentences work in a real, high-stakes composition. They teach you the formula, but they don’t teach you the rhythm. If you try to force these structures into your writing without understanding their purpose, you won’t sound sophisticated; you’ll just sound like you’re trying too hard.
I am not here to give you a theoretical lecture that you’ll forget the moment you walk into the exam hall. My promise to you is much simpler: I am going to show you how to use these structures to command attention and shift focus exactly where you want it. We are going to move past the textbook definitions and focus on the practical application that actually lands the marks. I’ve seen these same mistakes more than fifty times, and I’m going to make sure you aren’t one of them.

Mastering the Grammatical Structure of Clefts
When we look at the grammatical structure of clefts, I want you to stop thinking about them as “extra” grammar and start seeing them as tools for precision. At its simplest, a cleft sentence is just a way of breaking a single, plain sentence into two parts to highlight a specific piece of information. If you are transforming sentences into clefts, you are essentially taking a standard subject-verb-object pattern and splitting it with a focal point. This is where most students stumble; they try to force the structure without understanding where the weight of the sentence actually lies.
You will primarily encounter two types: it-cleft vs pseudo-cleft sentences. The it-cleft is your quick fix for immediate emphasis (It was the manager who called), while pseudo-clefts—often starting with “what”—allow for a more sophisticated, rhythmic flow (What we need is more time). In my nineteen years of marking, I’ve seen far too many candidates lose marks because they used a pseudo-cleft where an it-cleft was required for the specific context. Mastering this distinction is the difference between sounding like a textbook and sounding like a proficient user of English.
Using Cleft Sentences for Emphasis Without Errors
When we talk about using cleft sentences for emphasis, the goal isn’t just to sound fancy; it’s about precision. In my nineteen years of teaching, I’ve seen so many students try to force a cleft structure only to end up with a sentence that feels clunky or, worse, grammatically broken. The trick is knowing exactly what you are trying to highlight. If you want to draw the examiner’s attention to the subject, you use an it-cleft. If you are focusing on the object or the action, you’ll likely need a pseudo-cleft.
The most frequent error I see in my “list of fifty” is a failure to manage the relative clauses in cleft sentences correctly. Students often lose the connection between the introductory phrase and the actual focus of the sentence. For example, they might start with “What I need is…” and then fail to provide a coherent noun phrase to follow. If you want to land those top marks, you must ensure that the sentence focus and emphasis remain sharp and that the grammatical link stays unbroken. Don’t just transform sentences into clefts for the sake of it; do it because you have something specific to say.
Five ways to stop losing marks on cleft structures
- Watch your relative pronouns like a hawk; the most common error I see in my classroom is students using ‘that’ when they absolutely must use ‘who’ for people.
- Don’t forget the ‘be’ verb; a cleft sentence isn’t a cleft sentence without its structural anchor, and leaving out the verb is a quick way to signal to an examiner that you haven’t mastered the pattern.
- Keep your focus tight; the whole point of a cleft is to highlight one specific piece of information, so if your sentence becomes cluttered with extra clauses, you’ve defeated the purpose and lost the emphasis.
- Check your subject-verb agreement after the ‘it is/was’ construction; just because you’ve shifted the focus doesn’t mean the grammatical rules of the original sentence have changed.
- Avoid overusing them; while I want you to use clefts to show off your range, using them in every other sentence feels forced and unnatural—aim for precision, not repetition.
Final Thoughts on Mastering the Cleft
We have covered a lot of ground today, from the mechanical “it is… that” construction to the more sophisticated “what” clauses. Remember, the goal isn’t just to make your sentences longer or more complex; the goal is to use these structures to direct the reader’s attention exactly where you want it. If you can master the distinction between a standard declarative sentence and a cleft, you move away from the repetitive, predictable patterns that examiners see a thousand times a day. Don’t let a misplaced “that” or a broken connection between your subject and verb undo all your hard work. Precision is your best friend when you are trying to shift focus without losing grammatical control.
I know that studying these nuances can feel overwhelming, especially when you are staring down an exam date. But I want you to remember why we do this: we are turning rules into natural habits. When you stop thinking about the formula and start feeling the emphasis, you have truly succeeded. You aren’t just memorizing a template to pass a test; you are refining your ability to communicate with clarity and intent. Keep practicing, keep refining those structures, and don’t be afraid to make mistakes in your drafts—that is exactly how we identify the ones we need to fix. You can do this.
Frequently Asked Questions
If I use a cleft sentence to emphasize a specific part of my sentence, am I at risk of making my writing sound too formal or unnatural for the exam?
That is a perceptive question, and it’s one I hear often. The short answer is: yes, if you overdo it. Cleft sentences are like salt; a little enhances the flavor, but too much ruins the dish. If every paragraph relies on them, your writing will feel heavy and performative. Use them strategically to highlight a key point or a contrast, but let your natural, direct prose do the heavy lifting elsewhere. Balance is everything.
How can I tell whether I should use a "what-cleft" or an "it-cleft" when I'm trying to highlight a particular piece of information?
Think of it this way: use an it-cleft when you want to correct a misconception or single out one specific person or thing from a group. “It was John who called,” not “It was the phone.” Use a what-cleft when you want to focus on the action or the entire concept itself. “What I need is a coffee.” One isolates a subject; the other highlights a whole idea. Choose wisely; the distinction matters for your score.
Are there specific punctuation errors I should watch out for when I'm restructuring a sentence into a cleft form?
Honestly, the biggest trap is the comma. I see students try to “help” their cleft sentences by inserting a comma after the introductory phrase—something like, “What I need, is a coffee.” Don’t do it. A cleft sentence is a single, continuous grammatical unit. Adding that comma breaks the flow and, frankly, shows a lack of control. Keep it clean: no commas between the subject and the verb. Let the structure do the work.
