    Re: may i know???

    This is a big area. If we are talking about ability, then can is present and could past. If we are talking about a poissibility, then can is more likely than could and could have refers to a possibility in the past.

    Re: may i know???

    I can come tomorrow- I am certain of this
    I could come tomorrow- This means that it is possible if you agree, so it is less certain than 'can', less definite

    It could rain tomorrow- this isn't certain, but there's a chance of rain.

    Re: may i know???

    You're welcome, Gulrina. With these modal verbs (can, could, will, etc), the past tense is often used to talk about the future- past tense does not necessarily mean past time, and with the modals, it usually doesn't.
