Use of Should

Use of Should: Should is a modal verb in the English language. Modal verbs are a small group of auxiliary verbs that express various shades of meaning, such as necessity, possibility, ability, permission, advice, and more. “Should” is often used to indicate a sense of obligation, advisability, or expectation in a sentence. It can also suggest probability or likelihood.

Uses of Should-

Obligation: When “should” is used to express obligation, it implies that someone is expected to do something or follow a particular course of action because it is the right thing to do, or there are rules or expectations in place.



Example- As a responsible citizen, you should pay your taxes on time.

Advice: “Should” is commonly used to offer advice or recommendations, suggesting what is best or beneficial in a given situation.



Example- If you want to improve your vocabulary, you should read more books.

Expectation: “Should” can indicate an anticipated or likely outcome based on certain conditions or circumstances.

Example- The project should be completed by the end of the week if everything goes according to plan.

Probability: When used to express probability, “should” suggests that something is likely to happen or be true.

Example: The package should arrive tomorrow. (It is likely to arrive.)

Permission: In certain cases, “should” can be used to ask for or grant permission in a more polite or tentative manner. Example: Should I use your laptop for a moment? (Asking for permission to use the laptop.)

Regret or criticism: “Should” can also be used to express regret or criticism about a past action or decision.

Example: You should have been more careful. (Regret or criticism about not being careful enough.)

What does ought to mean?

The word “ought to” is another modal verb in the English language. Like “should,” it expresses ideas related to obligation, advisability, or desirability. “Ought to” is used to indicate a moral or logical necessity, often based on expectations, duty, or external standards. It suggests that something is the right thing to do or the appropriate course of action.

Uses of ought to

Obligation: When “ought to” is used, it implies a strong moral or ethical duty to perform a certain action or behave in a particular way.

Example: You ought to help those in need. (It is considered morally right to offer assistance.)

Advice: “Ought to” is frequently employed to provide advice or make recommendations about what one should do in a given situation.

Example: You ought to start saving for retirement early. (It’s recommended for your financial well-being.)

Expectation: “Ought to” can suggest an expected or anticipated outcome based on norms or logical reasoning. Example: If he studies consistently, he ought to excel in the exams. (Considering his efforts, success is expected.)

Probability: Similar to “should,” “ought” can express likelihood or probability, but it tends to be stronger in its sense of moral obligation. Example: The weather is clear, so the flight ought to arrive on time. (It’s highly likely to arrive on time.)

Historical or traditional practices: “Ought” can refer to actions or behavior that were customary or expected in the past, although it may not be as commonly used in modern English.

Example: People ought to show respect to their elders. (In the past, it was considered a customary practice.)
