- What is the difference between “can” and “be able to”?
While often interchangeable, “can” is generally used for present or general abilities, while “be able to” can be used in all tenses and is useful when “can” is not available (e.g., future tense). “Be able to” can also emphasize a specific achievement or instance of ability.
