Persuasive writing
Give a reason and use because.
Why we give reasons
When you want to persuade someone, you need to say why. A reason explains your opinion. It helps other people understand and maybe agree with you. The word 'because' is a special joining word that introduces your reason.
How to use 'because'
Put 'because' after your opinion. Then add the reason. For example: 'Dogs make great pets because they are loyal and friendly.' The part after 'because' tells us why dogs make great pets.
Strong reasons vs weak reasons
A strong reason gives facts or explains clearly. 'We should recycle because it protects the planet' is strong. 'We should recycle because I said so' is weak. Good persuasive writing uses clear, strong reasons.
Watch out for common mistakes
Don't use 'because' twice in one sentence. Don't forget the reason after 'because'. Always check: does my sentence have an opinion and a reason?
Worked examples

- Complete the sentence: 'Every school should have a library because books help children learn new things.'
2. Fix this sentence: 'Chocolate is the best flavour.'
- The sentence gives an opinion but no reason.
- Ask yourself: why is chocolate the best?
- Add 'because' and a reason: 'Chocolate is the best flavour because it tastes rich and sweet.'
3. Which word is missing? 'You should wear a helmet ___ it protects your head.'
- The sentence has an opinion (you should wear a helmet).
- It has a reason (it protects your head).
- The joining word 'because' links them together.
