transparant object with stroke - don't show layer underneath

[macerto]

Not sure how to describe it, but let's say I create a circle with transparant background a black stroke. Then I create a text. The text intersects with the circle (see image)

How can I keep the circle surface transparant but not show the layer below, so that part of the first letter doesn't show (see image)

Why do you want it to be transparent if it's supposed to hide things behind it?

It is not clear what you mean by this. By "transparent background" I assume you mean the circle has no fill but the "a black stroke" part is confusing because it looks like it has a cyan stroke in your image & the text below it does not show through.

I also don't understand what you mean about keeping the circle surface transparant but not showing the layer below, because if something is transparent it must show whatever is below it. That's what transparent means.

is this what you want:

 

this is how i did it

I think the OP means like this.

Thanks all for replying.

@firstdefence, that's exactly what I mean, thanks!

I apologise for not being clearer.

Ok you win

If the final output is to be raster, this can be done with just an Erase blend and an FX. And the text remains editable text. 
The important part is to "group" the eraser object with the stuff that needs to be erased. That way the elements underneath (pink here) aren't touched.
(the eraser shape (ellipse here) needs a fill at 100% opacity for the erase to work....the FX is Outline)

I'd prefer not to rasterise it because I'd like to use this technique is for printing on shirts. That's the reason I don't want to fill the object with a color. I've attached an image that should help make it clear what my objective was.

You can see a small part of the green T inside the object. No part of the T should show up inside the outlined object. There are probably different way to achieve this.

Again, sorry for the confusing post

In that case, convert the text to curves and edit the nodes on the T

Cool. Not confusing at all . If you want/need vectors stay with the boolean route as @firstdefence showed.
