The verb "can" means to be physically able or capable of doing something. I can speak French (I am physically able to do it; I know the words, I have the skill). But it is not correct to use "can" when asking permission. Use "could," which is considered more polite-- "Could I borrow your book? Could I use your computer?"
The verb "will" refers to an action that takes place in the future. I will study Spanish next year (I am not studying it now, but plan to do so later on). In questions, it can also mean "do you intend to"-- as in, "Will you be at the meeting?" But again, for permission, use "would": "Would you help me with my homework?"
As for "shall," it is a verb that is not as commonly used in American English as it used to be. It used to be a first person singular or plural (used with "I" or "we") to refer to a (definite or planned) future action, and it was considered polite: I shall go to visit my aunt next week. We shall see them at the wedding. But these days, "shall" and "will" are often used interchangeably, with one (shall) being more formal, and the other (will) being more conversational. In England, and in former British colonies, "shall" is still seen as the more polite or more correct form for the first person ("I" or "we"), whereas "will" is more definite and much stronger: "Yes I will take this course." But in America, you rarely hear "shall" as much as you did 100 years ago.
"Shall" is used to indicate a requirement or future action, often in a formal or legal context. "Should" is used to express a recommendation, obligation, or likelihood. For example, "You shall attend the meeting" indicates a requirement, while "You should prepare for the presentation" gives advice.
Use "may you" to wish something upon someone else. E.g. "May you have a pleasant day." Use "shall you" to ask someone what they will do. E.g. "Shall you take lunch now or later?"
"Shall" is used to express future tense or to make suggestions, offers, or promises. Whereas, "should" is used to indicate obligation, recommendation, or expectation. For example, "I shall arrive at 9 o'clock" and "You should finish your homework before going out."
"Shall" is used to indicate a strong recommendation or requirement, typically in a formal or contractual context. "Should" is used to express a milder recommendation or advice. For example, "You shall complete the assignment by Friday" implies it is mandatory, while "You should complete the assignment by Friday" suggests it is advisable but not mandatory.
Use "shall" for expressing a future action or intention, "should" for indicating a recommendation or expected outcome, and "must" for conveying a requirement or obligation. "Shall" is typically used in formal documents or legal contexts, while "should" and "must" are used in everyday language to express differing levels of necessity or urgency.
I shall tell you and you shall have the answer.
