Words differentiation

able - if someone or something is able to do something, they have skills or qualities which make it possible for them to do it.
capable - if a person or thing is capable of doing something, they have the ability, capacity, or potential to do it.
The different usage between able and capable is ' able ' has a broader meaning in one's ability but ' capable ' shows one's ability in a more specialized aspect.
She is an able teacher. ( She is a teacher with quality )
She is a capable teacher. ( She has the ability to be a teacher )
Capable also shows a sense of possibility whereas there is no such usage with able.
* The situation is capable of improvement.
In this situation, we can't replace capable with able to show the possibility for improvement.
Ability can be acquired through a series of training, but capability has nothing to do with training.
* I do not doubt his ability to do the work.
