A Sign - anything that makes meaning.
Can be a word, gesture, image, sound, object.
A sign as two components:
Signifier - the material; object or image being seen
Signified - meaning; message given off by images or object
Icons
clear representation of object itself, keeps characteristics
Index
indicate something
connected with its meaning, not arbitrary
compare to icon - it is not the object itself
example -smiles indicate happiness
Symbols
no resemblance to the real object
a result of convention
can only mean something if person knows (culture or previous knowledge)
Dove for Peace - no connection between the two, a convention
Letters and words are examples of symbols
Exercises:
