Hi,
I’m using Rymond Murphy english grammar. On unit 25 you can find:
"But can has only two forms, can (present) and could (past). So sometimes is necessary to use (be) able to:
Example: Tome might be able to come tomorrow. (can has no infinitive)"
But in the exercises I found this example:
“I can’t see you on Friday, but I can meet you on Saturday morning”
Why does he use can (present) in proposing a new date?
Would be more correct “I might be able to meet you on Saturday”?
