Help - Lacan's imaginary, symbolic, real

I came at these categories of Lacan’s from reading Zizek. I could never quite get a handle on them. I found Lacan himself even less helpful. Anyone have an idea what these three terms mean in the Lacan system?

To ante, I’ll give it a shot myself. Help me triangulate.

Imaginary -

this one seems the most like common usage. IOW stuff we imagine, images. The creations of a mind. Fantasy.

Symbolic - Somehow Lacan connects this word with Law and the father. Perhaps it is…no, I can’t even make a stab. I do know that this realm is where things are known by their differences, often, it seems in opposites. But I am quite confused here.

The Real - this I think I get the best, oddly enough. This is experiences which do not refer to anything else and cannot be reduced to anything else. They simply are and often overwhelmingly so - Zizek refers to the 9/11 planes hitting the buildings as an upsurgence of the real. The real seems to be grounding, but not necessarily pleasantly.

Here’s an online summation…

I’m too drunk to really elucidate my own (extremely limited) understanding of Lacan’s terminology - but i would recommend Bruce Fink’s book The Lacanian Subject for your perusal. It shoud help clarify a lot of these rather obtuse concepts.
