How do you say in English can the future?

"Can" is already in the present tense. To express the future with "can," you need to use the future tense of "can," which is "will be able to" or "will can".

Here are some examples:

* "I can go to the park tomorrow." (Present tense)

* "I will be able to go to the park tomorrow." (Future tense)

* "I will can go to the park tomorrow." (Less common, but grammatically correct future tense)

However, it's important to note that "will can" is not as common as "will be able to." In most situations, "will be able to" is the more natural and preferred way to express future ability.
