According to this definition, what is the word for a personal symbol? Emblem? Badge? Insignia? I know the definitions of those words, but I wonder whether or not one's symbol falls into either. Is there a dedicated term for this?
By personal symbol, I mean a symbol meant to represent someone. Since I was a child, I have been designing personal symbols for myself; those someway represent me. That is what I am referring to.
