Giving Advice with Should and Shouldn't
We use should and shouldn't to give advice or say what we think is a good or bad idea. It is weaker than 'must' — it's a suggestion, not an obligation.
Structure
- Positive: Subject + should + base verb. Example: You should drink more water.
- Negative: Subject + should not (shouldn't) + base verb. Example: You shouldn't skip breakfast.
- Question: Should + subject + base verb? Example: Should I call her?
How the Grammar Works
- 'Should' is the same for every subject — no 's', no change.
- Always follow 'should' with the base form of the verb, never 'to': 'You should rest', not 'you should to rest'.
- Use 'shouldn't' to advise against something: 'You shouldn't stay up so late.'
- Use 'Should I...?' to ask for advice or suggestions: 'Should we take an umbrella?'
Common Use Cases
- Giving advice: You should see a doctor.
- Making suggestions: We should try that new restaurant.
- Saying something is a bad idea: You shouldn't eat so much sugar.
- Asking for opinions: What should I wear tonight?
Frequent Mistakes and How to Avoid Them
- Adding 'to' after 'should': Incorrect: "You should to relax." Correct: "You should relax."
- Adding 's' to 'should': Incorrect: "She shoulds rest." Correct: "She should rest."
- Confusing 'should' with 'must': 'should' is a suggestion, 'must' is a strong obligation — don't use them as if they mean the same thing.
Comparison with Related Grammar
'Should' is much softer than 'must' or 'have to'. 'You must see a doctor' sounds like a strong warning; 'You should see a doctor' sounds like friendly advice that the person can choose to follow or not.
Example Sentences
- You should read this book, it's great.

- He should apologize to her.
- You shouldn't talk to strangers like that.
When to Use This Rule
Use 'should' and 'shouldn't' to give or ask for advice and opinions. It's a suggestion, not a strict rule — remember, no 's', no 'to'.
