Modal Verbs: Could, Should, Would
At one point in Sydney I was managing a team of fifteen staff across venues owned by Star Casino and Merivale — some of Sydney’s most demanding hospitality environments. I remember standing in a break room thinking: “I could stay here forever. The money is good, the team respects me. But I should make a change — I would regret it if I stayed just for comfort.” Those three words — could, should, would — captured an entire career crossroads in one breath.
🎯 Aim: By the end of this lesson you will be able to use could, should, and would correctly to express ability/possibility, advice, and hypothetical situations.
🔑 The Three Modals at a Glance
| Modal | Core Meaning | Example |
|---|---|---|
| could | Past ability; present possibility; polite request | I could handle a team of fifteen. |
| should | Advice; expectation; moral duty | You should update your CV regularly. |
| would | Hypothetical result; polite offer; habitual past | I would take the job if the role excited me. |
📖 Examples
- Possibility: You could apply for the management role — you have the experience.
- Past ability: When I worked in Sydney, I could open a bottle of wine in under thirty seconds.
- Advice: You should speak to your manager before making any decision.
- Regret (past): I should have left earlier — the commute was exhausting.
- Hypothetical: I would move back to Sydney if the opportunity arose.
- Polite request: Could you send me the schedule for next week?
💡 Key Rules
- All three modals are followed by bare infinitive (no to): ✓ should go ✗ should to go
- Could have + past participle = unrealised past possibility: I could have stayed, but I chose not to.
- Should have + past participle = past regret or criticism: You should have told me sooner.
- Would is NOT used in the if-clause of a conditional: ✗ If I would go… → ✓ If I went…
✏️ Practice Task
Choose could, should, or would to complete each sentence. More than one answer may be possible — be ready to explain your choice.

- When I was younger, I ________ run 10 km without stopping.
- ________ you pass me the wine list, please?
- If I had more savings, I ________ start my own restaurant.

Show Answers & Explanations
- should — giving advice about the present.
- could — past ability (no longer possible now).
- Could — polite request.
- would — hypothetical result in a second conditional.
- should have — past criticism / regret about an action not taken.
🚀 Takeaway
Master these three modals and you gain the ability to give advice, reflect on the past, and discuss possibilities with real nuance. They are the tools of a thoughtful, professional speaker of English.
