Question

can you tell me the use of shall will as well as use of should and would as a modal only.

Answer 1

Well, in traditional British grammar, the rule is that will should only be usedwith second and third person pronouns (you; he, she, it, they). With first person pronouns (I and we), the 'correct' verbto talk about the future is shall. ... Equally, not all varieties of British English use 'shall' in these senses.
