Expert writing Tips
Best practice
Use "be able to do" to express a potential or capability, rather than a definite action. For definite actions, use a simpler verb tense.
Common error
Avoid using "be able to do" when "can" suffices. "Can" already expresses ability, so saying "can be able to do" is redundant.

FAQs
What is the difference between "can" and "be able to"?
"Can" is a modal verb directly expressing ability or possibility. "Be able to" is a phrase that also expresses ability, but it can be used in tenses and forms where "can" cannot, such as future tenses ("will be able to").
How can I use "be able to" in a sentence?
Use "be able to" followed by a verb to indicate capability or possibility. For example, "I will be able to attend the meeting tomorrow" or "She wants to be able to speak Spanish fluently."
What are some alternatives to "be able to"?
Alternatives include "be capable of", "have the ability to", "manage to", or simply using "can" when grammatically appropriate.
Is it grammatically correct to say "can be able to"?
No, it's not grammatically correct. The modal verb "can" already expresses ability, so using "can be able to" is redundant. Instead, use either "can" or "be able to" depending on the tense and context required.
