Introduction to Can and Could
Unlock Audio Lesson
Signup and Enroll to the course for listening the Audio Lesson
Today, we'll start by discussing the modals 'can' and 'could'. Can anyone tell me what 'can' signifies?
'Can' is used to show ability.
Exactly! For example, *I can swim* shows someone's ability. Now, how about 'could'?
'Could' is also about ability but in the past?
Correct! You could also use 'could' for polite requests, like *Could you help me?* That's a great segue into how these two modals can change meaning based on context. One memory aid for these modals is 'Can is current, Could is past'.
So, can we say 'I could swim as a child'?
Absolutely! Great example, Student_3. To summarize, 'can' suggests present ability or permission, while 'could' suggests past ability and polite requests.
Exploring May and Might

Now, let's discuss 'may' and 'might'. What can someone tell me the difference in their usage is?
I think 'may' is more certain than 'might'?
Great observation! For example, *You may enter* conveys formal permission, whereas *It might rain later* indicates a slight uncertainty. Remember, 'may' is like higher confidence about a possibility, while 'might' shows less certainty.
So, can you use them interchangeably sometimes?
Sometimes, but it's best to use them according to how certain you feel about the possibility. For instance, you wouldn't usually say *You might enter* for permission. That's why it's better to think of 'may' as a formal way to grant permission.
Got it! May has more authority!
Exactly! In summary, 'may' shows permission or a strong possibility, while 'might' indicates a weaker possibility.
Understanding Must and Should

Next, we will focus on 'must' and 'should'. Who can explain the difference?
Must is for strong obligations, right?
Yes! For example, *You must wear a helmet* conveys a necessity. What about 'should'?
Should is more of advice or recommendation, like *You should study harder*.
Exactly! A quick memory aid is: Think of 'must' as a requirement and 'should' as guidance. Can anyone give me an example of 'must'?
You must follow the rules!
Perfect! So to wrap up, 'must' indicates obligation, while 'should' suggests advice.
Will and Would - Future Actions and Hypothetical Situations
Unlock Audio Lesson

Lastly, letβs talk about 'will' and 'would'. What do these modals convey?
'Will' indicates future actions, like *I will call you tomorrow*.
Absolutely right! And what about 'would'?
'Would' can be used for hypotheticals, like *If I were rich, I would travel the world*.
Correct! You can think of 'will' for straightforward future intentions and 'would' for situations that are conditional or imagined. Both can imply politeness as well, like asking something politely with *Would you mind...?*.
So they both deal with future actions but in different contexts?
Exactly! To conclude: 'will' refers to decisions about the future, while 'would' is used for hypothetical situations.

Can
- Ability: Used to express capability (e.g., I can swim).
- Permission (informal): Used to give consent (e.g., You can go now).
- Possibility: Indicates a likelihood (e.g., It can get very hot here in summer).
Could
- Past Ability: Indicates a skill in the past (e.g., I could run fast when I was young).
- Polite Request: Used for making requests (e.g., Could you please help me?).
- Possibility: Implies a less certain possibility (e.g., It could rain later).
May
- Formal Permission: Gives permission in a polite context (e.g., You may enter).
- Possibility: Suggests a likely outcome (e.g., She may be at home).
Might
- Slight Possibility: Indicates a minimal chance (e.g., It might snow tonight).
- Polite Suggestion: Gives friendly advice (e.g., You might want to check the time).
Must
- Obligation/Necessity: Indicates a requirement (e.g., You must wear a helmet).
- Strong Probability: Suggests a likely conclusion (e.g., He must be tired after such a long journey).
Shall
- Offer/Suggestion: Used often in legal contexts (e.g., Shall I close the door?).
- Formal Obligation: Used with I or we (e.g., You shall report to the principal).
Should
- Advice/Recommendation: Suggests what is best (e.g., You should study harder).
- Expectation: Indicates a likely event (e.g., The parcel should be here by now).
Will
- Future Action: Used for making future commitments (e.g., I will call you tomorrow).
- Volition/Promise: Expresses determination (e.g., I will always support you).
- Prediction: Indicates an anticipated event (e.g., It will be a sunny day).
Would
- Hypothetical Situations: Used in conditional statements (e.g., If I had money, I would travel the world).
- Polite Request: Softens requests (e.g., Would you mind opening the window?).
- Past Habit: Describes recurring past actions (e.g., When I was a child, I would play for hours).
Understanding these modals is essential for expressing nuanced attitudes in English communication.

Understanding Modals

Modals are auxiliary verbs that express the mood or attitude of the main verb. They never change form and are always followed by the base form of the main verb (except for 'ought to').
Detailed Explanation
Modals are special kinds of verbs that help convey how actions are viewed in terms of possibility, necessity, or permission. Unlike regular verbs, modals do not change according to the subject (e.g., I can, you can, he can, she can, etc.). They are always used with the base form of the main verb. An example is the modal verb 'can,' which expresses ability, permission, or possibility.
Examples & Analogies
Think of modals as helpers in a conversation. Just as a friend may encourage you to try something new, modals help communicate your thoughts and intentions. For example, if you say, 'I can swim,' you are using the modal 'can' to indicate your ability, much like saying 'I'm able to swim.'
Using 'Can'

- Can:
- Ability: I can swim.
- Permission (informal): You can go now.
- Possibility: It can get very hot here in summer.
Detailed Explanation
The modal 'can' has three main uses: first, it indicates ability (what someone can do), as in 'I can swim.' Second, it offers permission in an informal context, such as 'You can go now.' Lastly, it expresses a possibility, like saying 'It can get very hot here in summer.' This allows for varying degrees of certainty regarding an action.
Examples & Analogies
'Can' is like your permission slip for fun activities. Imagine you're at a pool party and your friend asks, 'Can I jump in?' If you say yes, you're giving them permission just like 'You can go now.' And if someone asks about the weather, saying 'It can get hot here in summer' means it's a possibility like predicting a game score.
Using 'Could'

- Could:
- Past ability: I could run fast when I was young.
- Polite request: Could you please help me?
- Possibility (less certain than 'can'): It could rain later.
Detailed Explanation
'Could' serves similar functions to 'can' but with some distinctions. It often refers to past abilities, such as 'I could run fast when I was young.' It can also be used to make polite requests, like 'Could you please help me?' Finally, it indicates possibility but with a lower certainty compared to 'can', as in 'It could rain later.'
Examples & Analogies
'Could' is like remembering your past adventures. When you say, 'I could run fast when I was young,' itβs like reminiscing about old times. When you ask someone, 'Could you help me with my homework?' you are doing it politely, like asking someone to lend you their favorite book.
Using 'May' and 'Might'
Unlock Audio Book
Signup and Enroll to the course for listening the Audio Book
- May:
- Permission (formal): You may enter.
- Possibility (more certain than 'might'): She may be at home.
- Might:
- Slight possibility: It might snow tonight.
- Polite suggestion: You might want to check the time.
Detailed Explanation
'May' is often used in formal situations to give permission; for example, 'You may enter.' It can also indicate a likelihood, as 'She may be at home' suggests there's a strong chance she's there. In contrast, 'might' implies a smaller chance of something happening, as in 'It might snow tonight', and it can also be used to suggest politeness, like 'You might want to check the time.'
Examples & Analogies
'May' feels like a formal invitation, like saying, 'You may leave the table after dinner.' Itβs polite and respectful. 'Might,' however, feels more casual, like when you casually suggest, 'It might rain later,' which feels less definitive, like a gentle nudge to keep an umbrella handy.
Understanding 'Must' and 'Shall'

- Must:
- Obligation/Necessity: You must wear a helmet.
- Strong probability/Logical deduction: He must be tired after such a long journey.
- Shall:
- Offer/Suggestion (with I/we): Shall I close the door?
- Formal obligation: You shall report to the principal.
Detailed Explanation
'Must' is a strong modal used to indicate necessity or obligation, such as in the phrase 'You must wear a helmet.' It can also convey a high likelihood, like 'He must be tired' β suggesting it's nearly certain. 'Shall' is more formal and is often used to offer suggestions or express duty, like 'Shall I close the door?' or indicate obligations with formal language, as in, 'You shall report to the principal.'
Examples & Analogies
'Must' is like your parent telling you, 'You must clean your room before going out.' It conveys a strong obligation. 'Shall,' however, might be used more in formal settings, like during a debate: 'Shall we move forward with our proposal?' This helps structure discussions, just like a referee clarifying rules.
Applying 'Should' and 'Will'
Unlock Audio Book

- Should:
- Advice/Recommendation: You should study harder.
- Obligation (less strong than 'must'): We should arrive on time.
- Expectation: The parcel should be here by now.
- Will:
- Future action: I will call you tomorrow.
- Volition/Promise: I will always support you.
- Prediction: It will be a sunny day.
Detailed Explanation
'Should' suggests advice or recommends actions, as in 'You should study harder.' It can also indicate expected behavior, like 'The parcel should be here by now.' In contrast, 'Will' is used for future actions, promises, or predictions, for instance, 'I will call you tomorrow,' 'I will always support you,' or simply predicting a dayβs weather, 'It will be a sunny day.'
Examples & Analogies
'Should' is like a friend suggesting, 'You should try that new restaurant; itβs good!' When giving advice, you steer someone gently like a compass. 'Will,' however, determines your plans, like confidently saying, 'I will finish my project by Friday,' as if setting a date on your calendar.
Exploring 'Would'

- Would:
- Hypothetical situations: If I had money, I would travel the world.
- Polite request: Would you mind opening the window?
- Past habit: When I was a child, I would play for hours.
Detailed Explanation
'Would' is often associated with hypothetical scenarios, as in 'If I had money, I would travel the world.' This modal can also be used to make polite requests, like 'Would you mind opening the window?' Additionally, it describes past habits, such as saying, 'When I was a child, I would play for hours.'
Examples & Analogies
Imagine if you were dreaming about an adventure: 'If I could go anywhere, I would travel the world.' In polite requests, saying, 'Would you mind passing the salt?' is courteous, like asking a friend to share a snack. And when reminiscing, saying, 'When I was a child, I would play for hours' sparks nostalgia, building stories of memorable games.
