my ability is to do or doing

[ademoglu]

Hi,

My ability is to play /playing the guitar.

Do both - gerund and the infinitive - sound OK?

Thanks.

What context would you use that sentence in?

 

[Amelot]

The infinitive would require a special context. It would sound a bit strange ordinarily, but I would not call it impossible. What sounds rather odd to my ear is "My ability is ...", so it is hard to tell about "play". I would expect "I can play the guitar" or "My talent is playing ..." or "My desire is to play ....".

The infinitive would require a special context.

That's why the OP was asked to tell us the context in which they would use it.

We generally wait for an answer before making our own guesses.
