Semiotics is branch of linguistics that studies how we read signs. It is useful to illustrators to have some grounding in semiotics as it provides a technical language to describe how images are coded and decoded. Amongst other concepts semiotics uses connotation and denotation
as a way of describing actual and intended meanings:

  • Denotation describes the obvious, literal things in an image.
  • Connotation describes the associations we have with that image. These associations are determined by our social, economic and personal perspectives.
