Meaning
In English grammar, can is a verb that belongs to the group called modal verbs. A modal verb adds meaning to another verb. It does not show an action by itself. It shows ability, permission, possibility, or request.
When teaching grammar, it helps to explain that can works with another verb. It always comes before the main verb. It never changes form for different subjects.
For example: I can read. She can read. They can read.
The word read stays the same. The word can also stays the same.
This makes can easy to learn and use in sentences.
