Semiotics Semiotics Glossary S         Semiotic square [Chandler]    Greimas introduced the semiotic square as a means of mapping the logical conjunctions and disjunctions relating key semantic features in a text. If we begin by drawing a horizontal line linking two familiarly paired terms such as `beautiful' and `ugly', we turn this into a semiotic square by making this the upper line of a square in which the two other logical possibilities- `not ugly' and `not beautiful' occupy the lower corners. The semiotic square reminds us that this is not simply a binary opposition because something which is not beautiful is not necessarily ugly and that something which is not ugly is not necessarily beautiful. Occupying a position within such as framework invests a sign with meanings. The semiotic square can be used to highlight `hidden' underlying themes in a text or practice.
