Modal verbs are used to express hypothetical conditions, suggestions, obligations, and more. The main modal verbs in English are can, could, may, might, must, shall, should, will, would. They are used to talk about ability, possibility, likelihood, necessity, obligation, habit, requests, offers, and permission. Understanding how and when to use different modal verbs is important for showing probability, capability, and other conditional meanings in English.

3. Modal Verbs
What are modal verbs?
Modal verbs are used to express certain hypothetical conditions, such as advice, capability, or requests.
Consider the difference between these two examples:
• I swim every Tuesday.
• I can swim every Tuesday.
The first example is a simple factual statement. The speaker participates in a swimming activity every
week on Tuesdays.
The second example uses the modal verb can. Notice how the meaning changes slightly. The speaker
does not swim every Tuesday; they’re saying they are capable of swimming every Tuesday if they need
to. It’s hypothetical.

Some things seem likely, but we don’t know for sure. In these cases, you
can use the modal verbs should and must to show probability without
certainty.
• Her parents must be so proud.

5. parents must proud Her so be.

6. baby should be by brother
asleep now My.

What if you want to recommend something, but not command it? If

Modal verbs can express a necessary action, such as an obligation, duty,

not necessary. Use the same modal verbs as with commands: must, have
to, or need to.

Habit
To show an ongoing or habitual action—something the subject does
regularly—you can use the modal verb would for the past tense and will
for the present and future. The phrase used to is also acceptable if you’re
talking about a habit that no longer exists.
• When I lived alone, I would fall asleep with music.
• I will arrive early and leave late to every meeting.
