Jules Gilliéron^[a] (21 December 1854 – 26 April 1926) was a Swiss-French linguist and dialectologist. Born and initially educated in Switzerland, he studied linguistics at the École pratique des Hautes Études in Paris, where he spent the remainder of his life. His mentors included Michel Bréal and Gaston Paris, who supported his academic career; Bréal helped him secure a lectureship at the École practique in 1883. He became a French citizen in 1886, a professor in 1894, and assistant director of the École practique by 1913, the same year he was awarded the Légion d'honneur.

Gilliéron's early publications in the field of linguistic geography included an 1880 study of the dialect of the Swiss town of Vionnaz and the Pétit Atlas phonétique de Valais roman ("Little Phonetic Atlas of Roman Valais"). In the latter, he developed the methods he would later apply to larger projects, such as the use of a pre-prepared questionnaire. He co-founded an academic journal, the Revue des patois gallo-romans ("Journal of Gallo-Romance Dialects"), with Jean-Pierre Rousselot in 1887. He used a novel phonetic transcription system, developed with Rousselot, for the Atlas Linguistique de la France ("Linguistic Atlas of France"; ALF), a complete linguistic atlas of the Gallo-Romance area. The ALF, which he produced in collaboration with a fieldworker, Edmond Edmont, was the first major linguistic atlas of a Romance language, and its methodology influenced subsequent works of linguistic geography. Karl Jaberg and Jakob Jud, two of Gilliéron's students, later applied his methods to Italy and southern Switzerland.

Gilliéron considered the proper object of etymology to be the whole history of words, rather than only their origins. He opposed the Neogrammarian view that language evolves through exceptionless laws of sound change, arguing that linguistic changes are not always uniform and are influenced by human psychology. He believed that speakers could only differentiate concepts for which they had discrete linguistic forms, and therefore viewed phenomena such as folk etymology as potentially "pathological" forces which could reduce the complexity and so usefulness of a language, and which require speakers to use "therapies" to counteract them. He has been called "the master of linguistic geography",^[1] and credited as the founder of scientific dialectology in France.^[2]

Biography

Jules Louis Gilliéron was born on 21 December 1854 in La Neuveville, near Bern in Switzerland,^[3] the youngest of the four sons of Jean-Victor Gilliéron and Méry Ganty.^[4] Jean-Victor had left a post as a primary-school teacher in the villages of Lutry and Aubonne in 1853,^[5] becoming a French-language teacher in the Progymnasium in La Neuveville.^[6] He taught in the Gymnasium for girls in Basel from 1866, and was also a respected amateur geologist and paleontologist.^[7] Jules's elder brother, born in 1850, was the artist and archaeological draughtsman Émile Gilliéron;^[8] another elder brother died in infancy.^[5] As children, the Gilliéron boys, including Jules, took part in Jean-Victor's geological expeditions.^[6]

Jules attended school in Neuchâtel, where his teachers included the dialectologist Cyprien Ayer [fr].^[9] In 1874–1875, he accompanied his eldest brother, Alfred, on a tour of the Eastern Mediterranean region, which spanned several months.^[8] He took his school leaving exams in the autumn of 1875: these were graded "satisfactory", in response to which Gilliéron wrote to the school's governing body, with his father's support, to refuse his diploma, on the grounds that it had been given to him "out of kindness" and judged inferior to those awarded before.^[10] He subsequently enrolled, in the winter of the same year, at the University of Basel, where he attended lectures by the historian Jacob Burckhardt, the linguist Jules Cornu [de], and the classical philologist and philosopher Friedrich Nietzsche.^[11][b]

Cornu advised Gilliéron to study under the linguists Paul Meyer, based in the French city of Chartres, and Gaston Paris,^[11] a lecturer at École pratique des Hautes Études in Paris who had developed Meyer's theories that dialects were not monolithic and that linguistic geography should therefore concentrate on individual linguistic features rather than dialect groups.^[1] In 1876, at the age of 22,^[13] Gilliéron moved permanently to Paris,^[14] where he attended from November lectures at the École pratique by Gaston Paris;^[15] by Michel Bréal, a prominent philologist of ancient Greek;^[8] by the linguist Arsène Darmesteter; and by the classical philologist Louis Havet. He also attended lectures by Meyer in Chartres.^[11] During his first academic year in Paris he delivered a lecture, at a conference organised by Havet, on the pronunciation of Vulgar Latin.^[16] After the 1876–1877 academic year, he studied primarily under Gaston Paris.^[11] In 1878, he began teaching German at the Lycée Chaptal, a secondary school.^[13] There, he taught advanced classes for students aspiring to study at the prestigious École polytechnique or at the Saint-Cyr military academy, using a version of the direct method he developed himself.^[15] During his time at the Lycée Chaptal, he also worked as a substitute professor at the Sorbonne. His salary rose from 800 francs in 1878 to 4,950 in 1891.^[17] In 1897,^[13] he resigned his teaching post to focus his work on the Atlas Linguistique de la France ("Linguistic Atlas of France"; ALF).^[18]

In January 1883, Gilliéron was appointed to succeed Arsène Darmesteter as a lecturer in linguistics under Gaston Paris. At the suggestion of Bréal,^[19] who had supported ihs elevation to the post,^[8] he lectured on dialectology. He became a French citizen in 1886,^[2] though continued to describe himself as Swiss, and to take holidays at a small property in Switzerland.^[20] Gilliéron was made an Officier d'Academie, a member of the honorific Ordre des Palmes académiques, in 1891.^[17] In 1894, he took the post of "Professor of Dialectology of Roman Gaul",^[21] created for him by Gaston Paris.^[22] By 1913 he was assistant director of the École practique, though Iordan later wrote that his salary at this point left him with barely enough to live on.^[23] In the same year, he was awarded the Légion d'honneur.^[24]

Gilliéron's university courses were well known and attended by many future linguists from around Europe;^[25] these included Iorgu Iordan and Albert Dauzat,^[26] later director of studies at the École pratique.^[21] His lectures initially covered Old French and the study of the living dialects of France. From the 1892–1893 academic year, a new section of the École practique for the study of the dialectology of Roman Gaul was created, separate from that (directed by Gaston Paris) dedicated to Romance linguistics: Gilliéron was placed in charge of it, with the title of deputy director. By 1917, he was promoted to the rank of director of studies, the same title as Gaston Paris had held in the 1890s.^[19]

At the end of his life, Gilliéron was affected by ill-health: Roques wrote of it as "an incurable disease which was fortunately kept hidden from him until the end". He was instructed by the secretary of the École practique to take convalescent leave in the spring of 1926. He returned to Switzerland,^[27] where he died on 26 April in Schernelz [de].^[28] He remained in post at the École practique until his death.^[13]

Linguistic work

Gilliéron took up the study of the Franco-Provençal dialect of Vionnaz in the Roman Valais region of Switzerland in 1877, using it for his diploma thesis at the École practique; he presented the thesis successfully on 20 April 1879.^[15] He published his results in 1880 as Patois de la commune de Vionnaz (Bas-Valais) ("Dialect of the Town of Vionnaz").^[29] The following year, he expanded the project into a phonetic atlas of the whole Roman Valais region.^[2] This atlas, the Pétit Atlas phonétique de Valais roman ("Little Phonetic Atlas of Roman Valais"), was an early example of the use of a pre-prepared questionnaire and direct fieldwork to conduct linguistic research,^[30] and the first phonetic atlas to be published on a Romance-speaking area.^[31]

In 1884, Gilliéron was approached by the Minister of Public Instruction to study the dialects of the langues d'oïl in southern Normandy.^[19] In 1887, he co-founded, with Jean-Pierre Rousselot,^[32] the Revue des patois gallo-romans ("Journal of Gallo-Romance Dialects").^[33] The journal was sponsored by Meyer and Gaston Paris,^[34] and was published until 1893.^[33] The phonetic transcription system used by this journal became known as the Rousselot–Gilliéron alphabet [fr].^[35]

The Atlas Linguistique de la France

With the encouragement of Gaston Paris,^[36] who secured funds towards the research and printing,^[37][c] Gilliéron embarked upon the Atlas Linguistique de la France after his monograph on Roman Valois. The ALF was intended as a complete linguistic atlas of the Gallo-Romance area, which included France, French-speaking Switzerland, Wallonia, western Piedmont and the Channel Islands.^[36] It was the first major linguistic atlas of a Romance language,^[39] and the first national linguistic atlas to be completed.^[40][d] Gilliéron tasked Edmond Edmont,^[36] a layman with highly sensitive hearing,^[41][e] to travel by bicycle throughout rural areas between 1896 and 1900,^[43] using a questionnaire which focused on several different phonological, lexical and semantic marks of distinction.^[44] Edmont asked questions in standard French, asking respondents to translate words or phrases into their local dialects.^[45]

The methodology of the ALF was predicated upon Gilliéron's twofold belief that the Gallo-Romance area could be analysed according to mechanistic dialectological laws, and that this could be done by interviewing speakers fluent in both a local dialect and Standard French, who would be able to identify and produce the dialect form of a given Standard French word.^[37] Gilliéron periodically updated the questionnaire, which initially tested 1,421 items but grew over three series to 1,920,^[46] each represented in its own map.^[40] He required Edmont to record only the first answer given by each interviewee so as to preserve, as far as possible, the repondents' basilectal response.^[25] Edmont conducted interviews in 638 different locations,^[47][f] using a single interviewee for each site,^[48][g] writing down the responses he received in the Rousselot–Gilliéron alphabet,^[50] and sending them to Gilliéron at the end of each day. These methodological innovations ensured the quality and commensurability of the data collected in the ALF.^[41] Gilliéron's method of using a trained, professional data collector, rather than volunteers from the dialect communities, became the norm in dialectology.^[51]

The ALF was published in thirteen volumes between 1902 and 1910.^[33] Although it received limited scholarly attention in France, it was popular among scholars in Germany, Switzerland, Austria and Scandinavia, many of whom were Gilliéron's former students.^[52] Gilliéron received the prize of the Diez Foundation in 1908 for the work.^[24] Hans Goebl, in 2016, credited the ALF with founding the modern study of areal linguistics (the field aiming to chart and explain geographic differences of language). Following Gaston Paris's theories, Gilliéron focused his analysis of the ALF's data on individual linguistic features, rather than attempting to impose a typology or dialectal labels upon them.^[52] Karl Jaberg and Jakob Jud, who both studied under Gilliéron, later collaborated on the Sprach- und Sachatlas Italiens und der Südschweiz ("Linguistic and Ethnographic Atlas of Italy and Southern Switzerland"), published in eight volumes between 1928 and 1940,^[53] which applied his methods but refined them by including urban areas and asking respondents to name concepts without first offering a standard form of the word in question.^[54]

Views on linguistics and language change

Gilliéron's approach to etymology, in contrast to that of previous generations of scholars, emphasised the whole history of words rather than focusing entirely on their origins. In 1919, he compared an etymology focusing only on words' origins with a biography of Honoré de Balzac that read in its entirety, "Balzac, sitting on his nanny's knees, was dressed in a blue-and-red striped gown. He wrote La Comédie humaine."^[55] Gilliéron's 1918 book, Généalogie des mots qui désignent l'abeille ("Genealogy of the Words Which Designate the Bee"), compared contemporary variants of a single word (abeille 'bee') to draw conclusions about linguistic change over time: it was the first attempt to do so systematically.^[56]

Gilliéron opposed the Neogrammarian school of linguistics, which taught that languages develop according to regular, exceptionless laws of sound change.^[57] He is often associated with the phrase "every word has its own history", and sometimes erroneously cited as its source.^[58][h] His work was in the early tradition of lexical diffusion, by which sound changes are seen as spreading gradually across a language, rather than, as the Neogrammarian view predicts, appearing uniformly and simultaneously.^[59] Unlike the Neogrammarians, he argued that human psychology plays a prominent role in linguistic change,^[60] and that various factors can result in sound changes spreading in a non-uniform fashion.^[61] Christos Nifadopoulos names him, alongside Hugo Schuchardt, as one of the most important opponents of the Neogrammarian movement.^[62]

Gilliéron viewed language as a social tool, and believed that speakers could only differentiate concepts for which they had discrete linguistic forms. He therefore viewed the reduction of lexemes in a language – caused by sound change, the convergence of linguistic forms via folk etymology, and the simplification of multi-word signifiers into single words^[i] – as a "pathological" situation which required correction.^[63] He considered that speakers use "therapies", continuing his medical metaphor, including the repurposing of existing dialect words to break a state of one word holding multiple meanings, the creation of completely new vocabulary for the same purpose, the borrowing of words from neighbouring dialects or the literary language; in the literary language itself, he further suggested that speakers may assimilate the spoken form of words to their written forms, which are often more distinct in French, or return to Latinate roots.^[64] At the time and since, other linguists judged that Gilliéron overstated the impact of homonymy, and that it harms communication only in limited circumstances.^[65][j]

Assessment

In 1954, Gino Bottiglioni called Gilliéron "the master of linguistic geography";^[1] Mitja Skubic [sl], in 2004, called him one of the most important Romance linguists of the early twentieth century.^[66] W. H. Veith, in 2006, called him the founder of scientific dialectology in France.^[2] Jürgen Lang writes that Gilliéron's prose can often be awkwardly expressed or difficult to interpret, as Gilliéron acknowledged, and that he often sought co-writers to mitigate this; in Lang's view, Gilliéron's sole-authored prose is often polemical and difficult to read.^[67] He also criticises Gilliéron for rejecting Neogrammarian linguistics. while generally adopting their position that sound change is regular. However, Lang praises his work with Jean Mongin (his co-author for a 1905 study of variants of scier 'to saw') for problematising the distinction between borrowed and inherited vocabulary, and that between the historical and geographic origins of a word.^[57]

In 2002, the publication of a 1998 conference on his work included the comment that Gilliéron had been comparatively overlooked in histories of linguistics, and that few studies to that date had concentrated in depth upon his work.^[68] The same study noted and challenged the view that Gilliéron merely collected linguistic facts without theoretical underpinning, suggesting that his work engaged with fundamental problems of language diversification, the role of speakers in the history of languages, and the proper methods of linguistic geography.^[69]

In an obituary, Iordan described Gilliéron as a modest man, who would have bristled to be referred to as a "scholar", who "worshipped no-one, admired no-one, and flattered no-one",^[70] and "in [whose] giant body there was hidden a soul with the naivité of a child ... which made him extremely likeable."^[71] Another former student, Oscar Bloch [fr], recalled Gilliéron's "two-hour, impassioned lectures", after which he would take his favourite students to Le Balzar [fr], a brasserie, to drink beer.^[72]
