Can I use "could" instead of "might" in the following sentences?
(suggestion) you might try phoning directory enquiries
(annoyance) you might at least say you're sorry
My son asked if he could give me back what he owned the following week.
Is MIGHT possible here in replacement of COULD?
My son asked if he could give me back what he owned the following week.Thanks.
both of them are acceptable answers
but the difference resides in the degree of certainty in your example.
might shows more degree of certainty than could
The original question for could was "Can I...?". Though this could just about suggest a question about the speaker's ability/possibilty, it almost certainly requests permission.
The original quetion for might was " May I ...?" This requests permission.
