[Grammar] How can present perfect describe my status

[Ab.m]

I've read before that present perfect describes my current status could anyone please explain this concept ?
For example when i say " I've written something " how can this describe my status

 

[jutfrank]

I have a status of having written something.

 

[Ab.m]

I have a status of having written something.

So thats what you mean when you say I've written something ?

 

[jutfrank]

So thats what you mean when you say I've written something ?

Yes.

 

[Rover_KE]

'I have a status of having written something' sounds unnatural to me.

I can't imagine why anybody would say that.

 

[Ab.m]

It would be more appropriate to say that we can use the present perfect to talk about the current status/state (of something/someone

In your sentence, the letter is in a completed state.

Thank you.
but completed state means that it's a finished action, or it means that the letter is ready or available now ?

 

[GoesStation]

If you say "I've written a letter," the act of writing is finished. You are no longer writing.

 

[andrewg927]

Without further context, "I've written a letter" and "I wrote a letter" pretty much mean the same thing.

 

[GoesStation]

They are rarely interchangeable in BrE.

Nor in the American version.

 

[andrewg927]

They are rarely interchangeable in BrE.

I said nothing about interchangeability. I just said they mean the same thing (or at least can mean the same thing) without further context.

 

[andrewg927]

Again, I never said they meant exactly the same thing. You are putting words in my mouth. I totally understand the differences between past simple and present perfect. I'm pretty sure I don't need a refresher for that. But as you insisted, here is one case where any differences are minuscule. "I wrote a letter to Tom yesterday. I'm ready to send it now". "I have written a letter to Tom. I'm ready to send it now".
