Should: uses, structure and examples
Should helps you give advice, make recommendations, express expectations and describe a mild obligation. Learn how to choose it precisely, build every sentence type and use should have to look back at the past.
Should is a modal verb. It is followed by the base form, does not change with the subject and does not need do or does. Its exact force depends on context.
What should means and how it works
Should is pronounced /ʃʊd/: the letter l is silent. Like other core modals, it has one form for I, you, he, she, it, we and they.
The shared idea is that an option seems good, right or likely from the speaker's point of view. It can therefore express advice, recommendation, expectation or moral duty without normally carrying the force of must.
- Use the base form after should: should call, not should to call.
- Do not add -s with he, she or it: she should call.
- Make the negative with should not or shouldn't.
- Put should before the subject to make a question.
Should in statements, negatives and questions
Only the position of should changes in questions. The main verb always remains in the base form.
| Sentence type | Formula | Example |
|---|---|---|
| Statement | Subject + should + base verb | You should keep a copy of the receipt.Keeping the receipt is the recommended action. |
| Negative | Subject + should not / shouldn't + base verb | You shouldn't decide while you are tired.Deciding while tired is not recommended. |
| Question | Should + subject + base verb...? | Should we confirm the booking today?The speaker is asking for advice. |
| Wh-question | Wh- + should + subject + base verb...? | What should I say in the interview?The question asks which action is best. |
