 Modal verbs are a special category of verbs that are used to express various degrees of possibility, necessity, ability, permission, and obligation in a sentence. They often modify the main verb and help convey the speaker's attitude or viewpoint. Here's an easy definition of modal verbs:



Modal verbs are small helper verbs that show how likely, necessary, or possible something is in a sentence. They express things like ability, permission, obligation, and preference. Examples of modal verbs include "can," "could," "may," "might," "must," "shall," "should," "will," "would," and "ought to."


Modal verbs can change the meaning or mood of a sentence, and they usually don't have a past or future tense. Instead, they combine with the base form of the main verb to create different meanings. Understanding modal verbs is important because they provide important information about the speaker's intentions, expectations, or requirements in a sentence.

Can modal
The modal verb "can" is used to express various meanings related to ability, possibility, permission, and requests. It is a versatile verb that allows us to convey different nuances in our communication. Here are the key aspects of "can":

Ability: "Can" is often used to talk about someone's ability to do something. It indicates that someone has the skill, capability, or knowledge to perform a particular action. For example, "She can swim" means she has the ability to swim.

Permission: "Can" is also used to seek or grant permission. When making a request, we can use "can" to ask for permission to do something. For instance, "Can I borrow your book?" Here, the speaker is seeking permission to borrow the book. Conversely, "You can use my phone" implies that permission is granted.

Possibility: "Can" can express the idea of possibility or likelihood. It suggests that something is possible or has the potential to happen. For example, "It can rain tomorrow" implies that there is a possibility of rain occurring.

Certainty and Deduction: In some cases, "can" is used to express certainty or deduction based on evidence or knowledge. It implies a high degree of probability. For instance, "He can't be at the party because he's out of town." Here, the speaker is deducing that the person is not able to attend the party based on the knowledge of their absence.

Offers and Suggestions: "Can" can be used to make offers or suggestions. For instance, "Can I help you with that?" implies a willingness to assist. Similarly, "You can try the new restaurant; it's excellent" suggests a recommendation or suggestion.

Prohibition: In negative form, "can't" or "cannot" can indicate prohibition or something that is not allowed. For example, "You can't smoke here" means smoking is prohibited in that location.

It's important to note that the use of "can" depends on the context, and its meaning can be influenced by other words in the sentence. Additionally, "can" does not have different forms for different subjects or tenses. It remains constant throughout, regardless of the subject or time frame.

Understanding the usage and meaning of "can" allows us to effectively communicate abilities, permissions, possibilities, and more in various situations.

Could modal
The modal verb "could" is a versatile verb that is used to express various meanings related to ability, possibility, past ability, polite requests, suggestions, and more. It is the past tense form of "can" and often carries a similar but slightly different connotation. Here are the key aspects of "could":
