One of the most common errors students make in IELTS writing is trying to impress others by being overly ambitious with their grammar. This is due to many students’ misconceptions that all of their sentences must be ‘(IELTS Writing complex sentence)‘ (they do not!) and their lack of grasp of what constitutes a ‘difficult’ sentence. Attempting to construct unnecessarily elaborate phrases leads to grammar errors, which can result in lost marks in a variety of areas.

The following topics will be discussed in this article:

  • How many ‘Complex’ sentences each paragraph truly requires
  • The definition of a ‘complex’ sentence
  • How to construct complex sentences
  • Examples to help us understand and apply what we’ve learned in class to our own IELTS writing complex sentence.

Let’s begin to learn to construct IELTS writing complex sentence:-

What does the examiner expect?

If you want to make IELTS writing complex sentence. Firstly you have to know what does the examiner is expecting from you and what he wants?

According to the examiners’ marking scheme scheme, in order to receive a band 6 for grammar, we must:

  • Mix basic and sophisticated sentences in your writing.

The following is the information for band 7:

  • Make use of a wide range of complicated structures.

This clearly implies that we should utilize complicated sentences in our writing, but it does not imply that we should aim to make every sentence difficult. I’ve noticed a combination of basic and sophisticated sentences in every band 9 response I’ve seen. The key is to know when to utilize them, which we’ll discuss further down. However, we must first comprehend what a complex statement is.

What is a complex sentence in IELTS writing?

The term ‘complicated’ appears to be the major issue here. In this case, complex does not imply difficult, lengthy, or remarkable. This is a typical misunderstanding that causes pupils to write extremely long and grammatically incorrect sentences that are difficult to comprehend.

Consider the following scenario:

‘Global warming is one of the most prominent themes in the modern world, producing numerous environmental issues and challenging tasks as a result of its significant implications.’

This is a typical sentence from an essay that tries to be too complicated. This student attempted to condense four easy ideas into a single paragraph, but the outcome is a clumsy and incomprehensible sentence. They’ve lost control of the grammar, which has a negative impact on the meaning. When meaning is impacted, it prevents the reader from comprehending what is being said, which is extremely detrimental to your IELTS writing band scores.

‘Complex’ sentences are simply two or more simple sentences joined together. Putting them all together improves the essay’s coherence and consistency.

Let’s have a look at the first example once more. There are four simple ideas in the text above that we may convert into simple sentences:

1. These days, global warming is a hot topic.

2. Environmental issues are exacerbated by global warming.

3. Global warming poses a number of difficult difficulties.

4. Global warming has major ramifications.

We will lose marks in the IELTS exam if we write all of our phrases like this since they are too simple. All we have to do now is combine them to form complex sentences.

Complex Sentence Examples

Consider the following scenario:

Global warming is one of the most prevalent environmental difficulties, and it generates a slew of major consequences. There are significant obstacles involved with this topic, and its repercussions are extremely dangerous.

These lines, in my opinion, do not include anything ‘complicated,’ but rather simple thoughts that have been put together in a straightforward manner.

The term “complex” is merely a label, not a description.

I’ve taken each of the four simple sentences and combined them into two more complex sentences. As a consequence, you’ll have a grammatically correct and easily understandable text.

When should I use complex sentences?

When expressing major points, we should generally employ simple sentences, which are usually near the beginning of a paragraph. Then, when expanding on the main topic, such as when presenting a supporting example or illustrating your major thesis, we should employ complicated phrases.


This is a debate over whether ‘fast food’ or ‘junk food’ should be taxed more heavily than regular food.

‘Raising taxes would boost prices and reduce consumption.’ Fast food restaurants would pass these levies on to customers in the form of higher costs, causing individuals to be unable to buy junk food. Organic food, for example, has proven to be prohibitively expensive for most people. Despite this, many people in industrialized countries, where the problem is most severe, can afford price increases and will continue to consume high-fat foods.’

The first sentence is known as the ‘subject sentence,’ and it expresses the major idea. As a result, it’s fine if this is a basic sentence.

The second phrase elaborates on the main topic and uses the word ‘and’ to join two basic statements into a single complicated one.

The third sentence employs the linking phrase ‘for instance’ to give an example. The final statement is both a concession (showing the argument’s limitations) and a complex sentence (tying multiple ideas together).

This paragraph meets the marking criteria since it contains a combination of simple and sophisticated sentences.

How do I make a complex sentence?

Remember that a complicated statement is made up of more than one simple sentence strung together. As a result, we must study and practise employing the many grammatical structures that enable us to do so. Here are a few examples of how we might connect ideas in a statement.

We usually need two clauses to form a complex sentence: a dependent clause and an independent clause. A clause is a collection of words that includes a subject and a verb.

‘….because the weather was cold,’ for example, is an example of a dependent clause. Because it has a subject and a verb, yet it doesn’t make sense on its own, it’s a dependent clause. We need to add an independent clause to make sense.

An independent clause, as the name implies, can stand on its own. ‘I donned a warm coat,’ for example. We create a complex statement if we combine these two clauses: ‘I wore a warm coat because the weather was cold.’

As you can see, ‘complex’ statements need not be difficult. Now let’s look at some other ways to construct complex sentences.

1. Relative clause

Relative clauses can be used to provide crucial or additional information about a person, place, or item. This improves the fluency and coherence of our writing. This is accomplished by employing relative pronouns such as who, which, and that. ‘He’s the kind of person who is usually pleasant,’ for example.

Consider the following scenario:

Air pollution can be harmful to one’s health. Motor vehicles are a major source of air pollution.

Using the word ‘which,’ we may combine these two simple sentences into a single complicated sentence.

Air pollution, which is primarily caused by automobiles, can be harmful to one’s health.

Consider the following scenario:

It’s been proven that some people are more likely to smoke than others. These people have cigarette-smoking parents and pals.

The word ‘that’ can be used to connect both of these phrases.

There is evidence that people who have cigarette-smoking parents and friends are more prone to smoke themselves.

2. Subordinate Clauses (IELTS Writing complex sentence)

A subordinate clause can be used to describe nouns and pronouns, as well as verbs, adverbs, and adjectives. It can also be used to act as the subject or object of another clause. They’re constructed by using terms like because, while, until, even though, although, when, and if to connect an independent sentence with a dependent clause.

3. Conditional clauses (IELTS Writing complex sentence)

Also known as ‘If clauses’, they are used to express that the action in the main clause can only take place if a certain condition is met.

For example: (IELTS Writing complex sentence)

  • If I had a million dollars, I would quit my job.
  • I will be really happy if I pass the IELTS test.
  • These clauses are good for giving examples in IELTS writing part 2.

‘Increasing taxes would raise prices and lower consumption. Fast food companies would pass on these taxes to consumers in the form of higher prices and this would lead to people not being able to afford junk food. If the cost of organic food proves prohibitively expensive for most people, they will simply not buy it. Despite this, people in many developed countries, where the problem is most acute, can afford price hikes and will continue to eat high-fat meals.’

They’re also handy for discussing fictitious circumstances or speculating on past or present outcomes.

I’ll go over the four main types of conditionals in more detail below:

When talking about genuine or factual information, zero conditionals are used. To introduce the conditional, we might use if or when.

For example, when we travel vast distances nowadays, we normally fly.

First conditionals are used to discuss topics that are happening now or in the future.

For example, if the city’s population continues to rise, more infrastructure will be required.

Second conditionals are used to discuss things that are impossible to happen.

For example, we wouldn’t have any life on Earth if the sun didn’t rise tomorrow.

Third conditionals are employed to make predictions about the past. It’s frequently used to express regret or to imagine a prior unreal circumstance.

For example, if Germany had received a more equitable peace settlement after World War One, the Second World War would never have occurred.

4. Compound Sentences

Compound sentences consist of two independent clauses linked together with a conjunction such as ‘and’, ‘for’ or ‘but’.

Examples: (IELTS Writing complex sentence)

  • I really want to study, but I’m too tired.
  • She got to the test center early, and she did really well on her IELTS test.

Some students believe that these statements are too simple to be considered complicated, however this is incorrect.

You should avoid:-

Before taking the IELTS test, it’s critical to grasp and be able to employ these grammar structures. Some students memorize a lot of structures and try to use them in their writings without really thinking about how they operate or whether or not they are correct. This will only result in phrases that are awkward and incoherent. Remember that your sentences must be devoid of errors, so only utilize structures that you are comfortable with.

The idea is to only utilize them when necessary. Concentrate on answering the issue, and these structures will come effortlessly if you know how to utilize them.

Next step should be (IELTS Writing complex sentence)

I hope that this post has proved that you can write your ideas down in a clear and simple manner while still meeting the complex sentence marking requirements.

When practicing IELTS writing questions, try to think of what you want to express in basic sentences first, then consider how they might be linked to form complex statements. It will become second nature after enough practice, and your writing will vastly improve.
