Definition of ‘Can’ as a Modal Verb
The word “can” is a modal verb, also known as a modal auxiliary verb. Modal verbs are a type of auxiliary verb used to express modality, which includes concepts like possibility, necessity, permission, ability, and obligation. “Can” primarily indicates ability or possibility and is frequently used to ask for or give permission, make requests, and offer suggestions. It always precedes the main verb in a sentence and does not change its form regardless of the subject.
In essence, “can” acts as a helper to the main verb, adding a layer of meaning related to the potential or capability of performing the action described by the main verb. Unlike regular verbs, “can” does not take “-s” in the third-person singular form (e.g., “he can,” not “he cans”).
Its negative form is “cannot” (written as one word) or the contraction “can’t.” The use of “can” significantly influences the tone and intent of a sentence, making it a crucial element in effective communication.
Structural Breakdown of Sentences with ‘Can’
When constructing a question that begins with “can,” the basic structure is as follows: Can + Subject + Main Verb + (Object/Complement)? This structure inverts the typical subject-verb order found in declarative sentences. For instance, instead of “You can swim,” the question form becomes “Can you swim?”
Let’s break down each component:
- Can: The modal verb that initiates the question, indicating ability, permission, a request, or a suggestion.
- Subject: The person or thing performing the action (e.g., I, you, he, she, it, we, they).
- Main Verb: The action being performed (e.g., swim, help, go, see). The main verb is always in its base form after ‘can’.
- Object/Complement (Optional): Additional information that completes the meaning of the sentence (e.g., “Can you help me?”, “Can we go to the park?”).
For example:
- Can I borrow your pen? (Permission)
- Can she speak French? (Ability)
- Can you help me with this? (Request)
- Can we go now? (Suggestion)
Types of Questions with ‘Can’
Starting a sentence with “can” typically forms a question. The type of question depends on the context and the intention of the speaker.
The most common types of questions formed with “can” are:
Asking for Permission
When “can” is used to ask for permission, it inquires whether someone is allowed to do something. While considered less formal than “may,” it is widely accepted, especially in informal contexts.
For example, “Can I leave early today?” seeks permission to depart before the usual time.
Inquiring about Ability
This usage of “can” questions whether someone has the skill or capability to perform a specific action. For instance, “Can you play the piano?” asks if the person possesses the necessary musical skills.
The response confirms or denies the individual’s ability.
Making a Request
“Can” can also be used to make a request, asking someone to do something. This is generally considered less direct and more polite than a command.
For example, “Can you pass the salt?” is a polite way of asking someone to hand over the salt.
Offering a Suggestion
Starting a sentence with “can” can offer a suggestion or a possible course of action. This usage proposes an idea or a plan.
For example, “Can we try a different approach?” suggests considering an alternative method.

For example, “Could you please pass the salt?” is more polite than “Can you pass the salt?”
Another nuance involves the use of “can” in rhetorical questions. These questions are not meant to be answered but are used to make a point or express an opinion.
For example, “Can you believe he said that?” does not seek information about the listener’s ability to believe but rather expresses incredulity.
Additionally, the intonation used when asking a question with “can” can subtly alter its meaning. A rising intonation at the end of the sentence is typical for questions, but the specific pitch and emphasis can convey surprise, skepticism, or genuine inquiry.
