Hello fellow Grammarians:

I have a question regarding the field of "semiotics" (the theory and study of signs and symbols; reading signs-for those who aren't familiar). Is semiotics a science unto itself or is it a branch of linguistics? The reader I am using in one of my freshman writing courses, Signs of Life, uses a semiotic approach to interpreting literature and other cultural texts. One of my students asked me today if semiotics is used in any other fields aside from English studies and language. Any thoughts?

Thanks much.
