It's my attempt to simply the meaning, bringing it into modern vernacular and understanding.
sémainó - "Definition: to give a sign
Usage: I signify, indicate, give a sign, make known. from séma (a sign, mark)"
Symbol - "a mark or character used as a conventional representation of an object, function, or process; a thing that represents or stands for something else, especially a material object representing something abstract"
Throughout the text, John says, "...and I saw another sign..." and it be a detailed object or event.
It's the same way prophecy was given to Daniel, through symbolic objects that representing literal, physical entities or events. And many times those symbols (or signs, if you will) were explained for what they really represented.

It might not simplify the vernacular as it is used in Revelation 1:1 though in that it explains it's own meaning of it's usage by stating " he signified it by(exactly how) sending it through his angel. So He(Jesus) explains his intention himself.
