Study Notes
Modal Verbs: Usage in Sentences
-
Modal verbs are auxiliary verbs that express necessity, possibility, permission, ability, or obligation. They are followed by the base form of the main verb.
-
Common modal verbs include: can, could, may, might, will, would, shall, should, must, ought to.
-
Ability: "Can" and "could" express ability in the present and past, respectively.
-
Example: I can swim. (Present ability)
-
Example: I could swim when I was younger. (Past ability)
-
Possibility: "May," "might," and "could" express possibility.
-
Example: It might rain later. (Low possibility)
-
Example: You may have a headache.
-
Permission: "May," "might," and "can" (less often) can express permission, but this usage is more formal than their possibility applications.
-
Example: May I leave early today?
-
Obligation/Necessity: "Must," "should," "ought to," and "have to" express obligation or necessity.
-
Example: Parents must feed their babies. (High degree of obligation)
-
Example: I have to meet my obligations. (Generally used as an indication of necessity or obligation.)
-
Should/ought to: Often express advice or recommendations.
-
Example: You should study more regularly. (Advice)
-
Example: You ought to be more considerate. (Suggestion of appropriate behavior)
-
Will/would: Expressing future actions, willingness, or repeated habits / likely predictions.
-
Example: I will finish the task today.
-
Example: I would like to go out for dinner. (Indicates desire)
-
Example: I would often go out on Saturdays. (Habit in the past)
-
Important Note on "Have to" and "Must": Although both express obligation or necessity, "must" often suggests a stronger obligation that comes from a rule or law, while "have to" typically indicates a necessity stemming from a circumstance or situation.
-
Example: You must follow the rules. (obligation from regulation)
-
Example: I have to go to the bank. (necessity arising from a practical situation)
-
Form: Modal verbs are usually followed by the base form of another verb (also known as the infinitive).
-
Example: Will you come?
-
Example:* Could* I speak to your manager?
-
Negative forms: Simply add "not" after the modal verb.
-
Example: You cannot do that.
-
Example: She should not act in such a manner.
-
Example: They might not arrive on time.
-
Question forms: Place the modal verb before the subject.
-
Example: Can you help me?
-
Example: Would you be able to give me a hand?
-
Emphasis: Modal verbs can be used for emphasis.
-
Example: I must see that movie.
-
Example: You should do this job yourself.
-
Past Modals: The past modal forms, such as "could," "would," and "might," describe past actions or situations in terms of ability, possibility, or behavior.
-
Example: She could have won the award. (possibility in the past)
-
Modal Verbs and Tense: Modal verbs can be used with different tenses by using other auxiliary verbs (e.g., "have" for perfect forms).
-
Example: Would you have been able to go to the party? (past perfect modal)
-
Example: Will you have been able to go tomorrow? (future perfect modal)
-
Emphasis and Emphasis related use: Using modal verbs with more nuance or to provide different emphases. Modal verbs can create different levels of emphasis regarding suggestions or recommendations.
-
Example: You must not eat that food immediately. (strong prohibition)
-
Example: You should not eat that food immediately. (a more suggested prohibition)
-
Special Cases and Further Considerations: Modal verb usage can differ depending on specific contexts or situations. Consider the speaker's attitude and the force of the statement.
-
Example: I can go to the store for you. (expressing ability)
-
Example: I could go to the store for you. (emphasizing a possibility or expressing politeness, or potential).
