    can VS will be able to

    I will be able to speak French at the end of this course. (I feel less confident)

    I can speak French at the end of this course. (I have confidence & the future is based on the current circumstances & there is a great possibility that I can speak French later, so can I use "can" instead of "will be able to"?)

    wholehearted gratefulness.

    "I will be able to speak French at the end of this course" expresses absolute confidence. No, you can't use "I can be able to..."

    I don't think panicmonger is asking about 'can be able to'. He wants to know if he can say 'I can speak French at the end of this course.'

    If you will allow me, May I know the reason why "can" cannot be used in this context even if I have very much confidence and my French test results are excellent so according to the current trend, there is a very certainty that I can speak French at the end of this course.

    Re: can VS will be able to

    Can is a defective verb;

    In linguistics, a defective verb is a verb with an incomplete conjugation. Defective verbs cannot be conjugated in certain tenses, aspects, or moods.
    (Wikipedia)

    It has no infinitive and is only used in the present tense.

    Yes, but when it implies the idea of possibility or opportunity, rather than innate or learned ability, it can be used to refer to the future:

    I can see you at 4.30 tomorrow.

    One could say that although the appointment is tomorrow, "can" refers to the present. The speaker is expressing (her)(his) present ability to do something tomorrow.
    Maybe an hour ago (s)he couldn't see you tomorrow, but now (s)he can.

    Yes.

    But note that could itself can also be used with present idea (distanced for likelihood).

    I could see you tommorow.

    The possibility is more remote than with:

    I can see you tomorrow.

    I agree with you. To make it clearer, one may rewrite it as follows: "[I strongly believe in myself] I can speak French at the end of that course." However, my thought went for "will be able to" at first.
