compare..... to liken one thing to another or to look at one thing and determine how it is the same or different than another thing. Very often one says... compare and contrast..
Beyond compare means there is no comparison, and thus, it means the thing described as "beyond compare" is the very best.
I think there's some pop song that has the line.... "nothing compares to you" .. meaning you are unique.
And nice little "Tale" Mary.
