be able to

Possess the capability

Be able to expresses capacity or capability—having the skill, resources, or opportunity to do something.

It often substitutes for can, especially in tenses where can has no form: I want to be able to swim by summer, She's never been able to explain it.

The phrase also conveys possibility: You might be able to catch the last train.

Unlike can, be able to emphasizes achievement of a specific action rather than general ability.
