They mean nearly the same thing, the only difference is in their usage. "She is an able woman" = "She is a capable woman" "He is able to dance (simple verb)" = "He is capable of dancing (used as a noun)"

be able to capable of

разницы никакой. мне больше нравится использовать "capable of". солиднее звучит))))))))))))))))) плюс после "capable of" Герундий, помнишь же?

First of all, both are (adj) You can use (able): 1/ when you can do some thing 2/ We always put "To" after (Able) followed by a base form verb e.g. I am able to learn English. You can use (capable) 1/ When you are capable of doing something 2/ It always comes before Gerund (ING form) e.g. I am capable of taking care of my daughter This difference is only in terms of grammar but there is another obvious difference in usage, it is as follows: You can use it as an adjective before nouns: e.g. You are a capable learner

"cap" :)))))
