Definition

Can and can be are both modal verbs in the English language. The verb "can" is used to express ability, possibility, permission, or to make a request. For example, "I can swim" or "Can I go to the bathroom?" On the other hand, "can be" is used to indicate possibility or potentiality in a given situation. For example, "The problem can be solved with some effort."

Usage

The verb "can" is used in a variety of contexts to express different meanings. It can be used to talk about abilities, as in "I can speak Spanish." It can also be used to talk about possibilities, as in "It can rain tomorrow." Additionally, "can" can be used to ask for permission, as in "Can I borrow your pen?" On the other hand, "can be" is used to talk about potential outcomes or solutions to a problem. For example, "The issue can be resolved with proper communication."

Form

The verb "can" is an irregular verb in English, meaning it does not follow the typical conjugation patterns of regular verbs. The base form of "can" remains the same in all persons (I can, you can, he/she/it can, we can, they can). However, the negative form of "can" is "cannot" or "can't." On the other hand, "can be" is formed by combining the modal verb "can" with the base form of the verb "be." The negative form of "can be" is "cannot be" or "can't be."

Additionally, both "can" and "can be" can be used to make requests or ask for permission in different contexts.

Differences
