“Can” and “could” are both modal verbs in English, and they are often used to express ability, possibility, permission, or requests. However, there are some differences in their usage.
Can is typically used for present abilities, permissions, or possibilities. Could is often employed for past abilities, more polite requests, and hypothetical or conditional situations.
Can is straightforward and direct, while could adds a layer of politeness or implies a condition or hypothetical scenario.
