LISP is one of those things.
Its impossible to describe to people because its underlying premise is different.

Its like trying to describe a 2 wheeled motorcycle to a person who had only ever worked on 4 wheeled cars.
Its just different.

But, that difference make certain things really simple.
Like trying to describe thought processes, and thus AI.

Like the print command understands one and multiple, and thus will change syntax.

Our Hero had a sword
Our Hero had two swords

Nothing like the basic, blocky, error prone, printf() of C

I hope you enjoy your learning curve.
