Émile Benveniste (French: [emil bɛ̃venist]; 27 May 1902 – 3 October 1976) was a French structural linguist and semiotician. He is best known for his work on Indo-European languages and his critical reformulation of the linguistic paradigm established by Ferdinand de Saussure.
 Benveniste was born in Aleppo, Aleppo Vilayet, Ottoman Syria to a Sephardi family. His father sent him to Paris to undertake rabbinical studies, but he left the Rabbinical School after receiving his baccalauréat, and enrolled in the École pratique des hautes études. There he studied under Antoine Meillet, a former student of Saussure, and Joseph Vendryes, completing his degree in 1920. He would return to the École pratique des hautes études in 1927 as a director of studies, and would receive his doctorate there in 1935, with his major thesis on the formation of noun roots, and his secondary thesis on the Avestan infinitive. Following Meillet's death in 1936, he was elected to the Chair of Comparative Grammar in the Collège de France in 1937. He held his seat at the Collège de France until his death, but ceased lecturing in December 1969, after suffering a stroke that left him aphasic. Earlier that year he had been elected as the first President of the International Association for Semiotic Studies, and stayed nominally in that position until 1972. Benveniste died in a nursing home in Versailles, aged 74.
 At the start of his career, his highly specialised and technical work limited his influence to a small circle of scholars. In the late thirties, he aroused some controversy for challenging the influential Saussurian notion of the sign, that posited a binary distinction between the phonic shape of any given word (signifier) and the idea associated with it (signified). Saussure argued that the relationship between the two was psychological, and purely arbitrary. Benveniste challenged this model in his Nature du signe linguistique.
 The publication of his monumental text, Problèmes de linguistique générale or Problems in General Linguistics, would elevate his position to much wider recognition.  The two volumes of this work appeared in 1966 and 1974 respectively.  The book exhibits not only scientific rigour but also a lucid style accessible to the layman, consisting of various writings culled from a period of more than twenty-five years.  In Chapter 5, Animal Communication and Human Language, Benveniste repudiated behaviourist linguistic interpretations by demonstrating that human speech, unlike the so-called languages of bees and other animals, cannot be merely reduced to a stimulus-response system.
 The I–you polarity is another important development explored in the text.  The third person acts under the conditions of possibility of this polarity between the first and second persons.  Narration and description illustrate this.
 You, on the other hand, is defined in this way:
 A pivotal concept in Benveniste's work is the distinction between the énoncé and the énonciation, which grew out of his study on pronouns.  The énoncé is the statement independent of context, whereas the énonciation is the act of stating as tied to context. In essence, this distinction moved Benveniste to see language itself as a "discursive instance", i.e., fundamentally as discourse.  This discourse is, in turn, the actual utilisation, the very enactment, of language.
 One of the founders of structuralism, Roland Barthes, attended Benveniste's seminars at École Pratique. Pierre Bourdieu was instrumental in publishing  Benveniste's other major work, Vocabulaire des Institutions Indo-Européennes in his series Le Sens commun at radical publisher Les Éditions de Minuit (1969). The title is misleading:  it is not a “vocabulary”, but rather a comprehensive and comparative analysis of key social behaviors and institutions across Germanic, Romance-speaking, Greco-Roman, and Indo-Iranian cultures, using the words (vocables) that denote them as points of entry. It makes use of philology, anthropology, phenomenology and sociology. A number of contemporary philosophers (e.g. Giorgio Agamben, Barbara Cassin, Nicole Loraux, Philippe-Joseph Salazar, François Jullien, Marc Crépon) have often referred to Benveniste's Vocabulaire and are inspired by his methodology and the distinction he draws between meaning (signification) and what is referred to (désignation). Jacques Derrida's famous work on "hospitality, the Other, the enemy" is an explicit "gloss" on Benveniste's ground-breaking study of host/hostility/hospitality in the Vocabulary.
