Structuralism analyzes systems by examining the relations between their smallest elements. In linguistics, Ferdinand de Saussure pioneered the study of langue (language as a system) rather than parole (individual speech). He viewed langue as a system of arbitrary signs made up of a signifier and signified. Langue exists socially and unconsciously for speakers. It is defined relationally rather than by the content of its elements. Claude Levi-Strauss later applied structuralist principles to anthropology and myth studies. Structuralism examines deep unconscious structures rather than surface phenomena.
