Clause Craft: Relative Clauses and Complex Sentences

🔍 Imagine you want to tell a friend about a dog. You could say: 'I saw a dog.' But that is not very exciting or precise, is it? Now try this: 'I saw a dog that had three legs and wore a tiny bow tie.' Suddenly the sentence is vivid and specific! That extra chunk of information — 'that had three legs and wore a tiny bow tie' — is called a relative clause. Relative clauses are powerful tools that let writers zoom in on exactly what they mean. In this lesson you will discover how they work, which special words introduce them, and how to punctuate them like a pro. 🐾

A clause is a group of words that contains a subject (who or what is doing something) and a verb (the action). A relative clause is a special type of clause that gives extra information about a noun. It is attached to that noun and begins with a relative pronoun. The relative pronouns you need to know are: who, whose, which, where, and that. The noun the relative clause describes is called the antecedent — that just means 'the noun it goes back to'. For example, in 'The girl who won the race was delighted', the antecedent is 'the girl' and 'who won the race' is the relative clause.

There are two types of relative clause and they are punctuated differently. A defining relative clause gives essential information — without it, you would not know which person or thing is meant. It does NOT use commas. For example: 'The pupil who forgot their homework had to stay behind.' Without 'who forgot their homework' we would not know which pupil. A non-defining relative clause adds extra, bonus information. Remove it and the sentence still makes sense. These clauses are separated from the rest of the sentence by commas. For example: 'Amara, who loves football, scored the winning goal.' The commas act like brackets, tucking the extra fact inside.

Relative clauses do not only sit at the end of a sentence — they can be embedded right in the middle! An embedded relative clause sits between the subject and the verb of the main clause. For example: 'The scientist, whose discovery changed medicine, received a Nobel Prize.' The main clause is 'The scientist received a Nobel Prize' and the relative clause 'whose discovery changed medicine' is slotted inside it. This creates a more sophisticated, flowing sentence. Embedding clauses is a technique that examiners and teachers love to see because it shows real control over sentence structure. Give it a try! ✍️

Let us pull everything together. A relative clause starts with a relative pronoun (who, whose, which, where, or that) and gives extra detail about a noun in your sentence. Defining clauses tell you which specific person or thing is meant — no commas. Non-defining clauses add bonus information about something already identified — use commas to separate them. You can embed a relative clause right inside a sentence to show off your writing skills. Using relative clauses well will make your writing more descriptive, more precise, and far more impressive.
