My question:
(a) Unfortunately, I cannot attend Friday's get-together.
(b) Unfortunately, I am unable to attend Friday's get-together.
(c) Unfortunately, I won't be able to attend Friday's get-together.
Grammar books say that the future tense of "can" is "will be able to".
If this rule is strictly applied, then only (c) would be grammatically correct, since the act of "attend" occurs in the future. But in fact it seems that (a) and (b) are often used.
Can "can" and "is/am/are able to" be used instead of "will be able to", regardless of what grammar books generally say?
Also, please tell me if there is any difference in formality of speech among (a) (b) and (c). |
The grammar books have gotten more than this wrong, Cosmos. English doesn't have a future tense but traditional grammar got so hung up on 'will' as the future tense of English that they missed all the other ways we have to express the future.
So, in a nutshell, yes, you can use the other ones you've mentioned/you mentioned. As to formality, they all sound fairly formal.
