sign | structural meaning

The sign has two aspects, which may be reflected in the form:

The signifier is the physical entity which expresses the sign: the sound, shape or texture. the signified is the concept or emotion conveyed byt the sign.

Signification, the link between expression and concept, depends upon rules, codes, which are tacitly accepted by a community, and these rules are area which semiotics seeks to explore.

Signs rarely occur in a fragmented, isolated fashion; if they did the possibilities for human communication would be much more limited.
