Ferdinand de Saussure (; French: [fɛʁdinɑ̃ də sosyʁ]; 26 November 1857 – 22 February 1913) was a Swiss linguist and semiotician. His ideas laid a foundation for many significant developments in both linguistics and semiology in the 20th century. He is widely considered one of the founders of 20th-century linguistics and one of two major founders (together with Charles Sanders Peirce) of semiotics/semiology.
