Understanding their usage will help you express advice, obligation, and expectations clearly and effectively.
Introduction to Modal Verbs
Modal verbs are a crucial part of English grammar, used to express necessity, advice, possibility, and other related concepts. Knowing when and how to use them correctly can make your communication more precise and polished.
1. Should
Should is commonly used to give advice or suggest what is proper or expected.
- Examples:
- You should drink more water to stay hydrated.
- We should leave early to avoid traffic.
- When you want to recommend something or express an expectation, "should" is your go-to verb.
2. Must
Must indicates strong obligation or necessity.
- Examples:
- You must wear a seatbelt while driving.
- Students must submit their assignments on time.
- Use "must" when you want to stress something that is required or obligatory.
3. Ought To"
Ought to is used to express moral duty or advice, similar to "should."
- Examples:
- You ought to respect your elders.
- We ought to help those in need.
- Although less common in modern speech, "ought to" adds a formal tone to advice or obligations.
Exploring Alternatives
1. Be Supposed To
- Be supposed to is used to describe what is expected or assumed to happen.
- Examples:
- You are supposed to attend the meeting at 10 AM.
- She is supposed to call us when she arrives.
- This phrase is often used to describe expectations or rules that are generally accepted.
2. Be Meant To
- Be meant to expresses purpose or intention.
- Examples:
- This gift is meant to show my gratitude.
- The event is meant to bring people together.
- Use this phrase when indicating the intended purpose or function of something.
Practical Uses and Examples
Using modal verbs in real-life situations helps solidify your understanding and ensures you're ready to apply them effectively. Here are some practical examples:

Tense Usage of Modal Verbs
Modal verbs often pair with different tenses to convey various meanings. Here’s how to use them:
Present Tense:
- You should eat healthy foods.
- He must complete the project.
- They ought to be more careful.
- You had better not be late.
Past Tense:

- They ought to have known better.
- You had better have finished the task.
Future Tense:
- You should arrive on time tomorrow.
- They must bring their ID cards next week.
- You had better start packing soon.
Using "Be Supposed To" and "Be Meant To" in Different Tenses:
Present Tense:
- I am supposed to call her today. (present expectation)
- This project is meant to finish next month. (present intention)
Past Tense:
- He was supposed to call yesterday, but he forgot. (past expectation)

Future Tense:
- You are supposed to start your new job next week. (future expectation)
- This training is meant to help you improve your skills. (future intention)
Important Considerations
Strength of Advice vs. Obligation
- "Should" and "ought to" are softer, more suggestive.
- "Must" and "had better" are stronger, implying obligation or warning.
Contextual Use:
- Always consider the context when choosing a modal verb. For instance, "must" is more authoritative, while "should" offers gentle advice.
Conjugation and Negation:
- Modal verbs don’t conjugate or change forms like regular verbs. The negative form simply adds "not" after the verb (e.g., "should not," "must not").
- Be supposed to and be meant to can be conjugated to match different tenses and forms:
- He is supposed to finish by tomorrow.
- They were meant to arrive early.
Common Mistakes and Tips for Avoiding Them
Confusing "Should" and "Must": Remember, must is for strong obligations, while should is for advice.
- Incorrect: You must try this new dish. (if it's just a suggestion)
- Correct: You should try this new dish.
Forgetting "To" After "Ought":
- Incorrect: You ought finish your work.
- Correct: You ought to finish your work.
Mixing Up "Be Supposed To" and "Be Meant To": Ensure you use "be supposed to" for expectations and "be meant to" for intentions.
- Incorrect: I’m supposed to buy flowers. (if it's intended as a gift)
- Correct: I’m meant to buy flowers.
