La langue est un systéme dont toutes les parties peuvent et doivent être considérés dans leur solidarité synchronique. - Ferdinand de Saussure

A linguistic system is a series of differences of sound combined with a series of differences of ideas; but the pairing of a certain number of acoustical signs with as many cuts made from the mass of thought engenders a system of values.

Speech has both an individual and a social side, and we cannot conceive of one without the other.

Language is a system whose parts can and must all be considered in their synchronic solidarity.
