Yea it's the distance between the centre(as in the part the tyre goes on not the diameter centre) and the hub mounting face.
So imagine a wheel standing up as it would be fitted to a car and your looking at it from the tyre or where the tyre would be fitted. Find the centre of the tyre mounting part and imagine a line cutting directly throught it to the other side, the distance between that line and the hub face is the offset

So the distance from where the part of the wheel bolts to the hubs outwards to the edge of the tyre is a positive ET and the reverse is true of negative??

Ya so if you can imagine moving the hub mounting face of the wheel in towards the inside of thw wheel - thats giving negative ET. And if you move it towards the outside of the wheel - its giving you positive ET.
Quer hard to xplain without drawing pictures and using hand movements ha!

A negative offset would be like mounting a wheel backwards if you could or getting a split wheel and fitted the barrel on the wrong way as this moves the centre line of the barrel to the other side of the hub face(where your wheel and brake meet)
This is all about the barrel part of the wheel, if the wheel hub face was in the centre line of the barrel this would be a zero offset, since wheels must go under a car this would mean moving the hub face towards the outside so the barrel can go under a car.
I was going to get a guide together ages ago as I was getting pm's about offsets all the time but it's fairly straight forward
