So my question came up because of the verb "try".
I'll give you an example of a situation: John is mad at Mary. So Peter tells Mary to try talking to him, to make things good between the two of them.
And then a fourth person comes in and says "What is Mary doing?", to what Peter replies "She is trying talking to him.". My doubt is: Can we have these two gerunds in this order? Does that make the sentece sound weird, or is it just me?
Because Mary isn't trying to talk to John, she is trying to make things better betwen the two of them, and she does that by talking to John. That's why I think that the gerund must be used after the verb try in this situation. But does it make the sentence sound weird?
