Gallo (endonym galo) is one of the Oïl languages spoken in Western Brittany, in western France. It is traditionally spoken in Ille-et-Vilaine, Loire-Atlantique, and the eastern parts of Morbihan and Côtes-d'Armor, on the eastern side of the Breton linguistic boundary running roughly from Plouha to the . The eastern limit of Gallo is less clearly defined, owing to the existence of a dialect continuum with neighboring Oïl languages such as , Norman, and Angevin. Some linguists therefore consider Gallo to extend into areas adjacent to historic Brittany, particularly within the broader region of the Armorican Massif.

Because there are no universally accepted criteria for distinguishing languages from dialects, there is no full consensus regarding the status of Gallo. Although it is primarily an oral language, it has been the subject of academic research and standardization efforts, and books in Gallo are published on a regular basis. Unlike Breton, however, Gallo does not benefit from a long tradition of political or institutional advocacy. Both languages were nevertheless jointly recognized as "languages of Brittany" by the Regional Council of Brittany in 2004.

As a Romance language, Gallo is very different from Breton, which is a Celtic language. Speakers are referred to as gallésants or Gallo speakers. The term "Gallo" originates from the Breton language; its use by speakers themselves is relatively recent, although it is attested in the press as early as the beginning of the 20th century. Many speakers simply use the term "patois", although this label is often regarded as pejorative.

Despite some initiatives to promote the teaching of Gallo in schools and universities, the language is endangered. Speakers are generally elderly, and intergenerational transmission is very weak. Gallo is classified as seriously endangered by UNESCO. Estimates of the number of speakers vary widely, with between 3 percent and 8 percent of the local population reported as being able to speak the language.

Definition Names

The term Gallo derives from the Breton word , meaning "foreigner (of a Romance-speaking background)", itself originating from a Celtic root.

The term can be compared with the Scottish Gaelic word , which also means "foreigner", and more specifically "a Scot who does not speak Gaelic" or "an inhabitant of southern Scotland", where the traditional language is Scots rather than Scottish Gaelic.

The feminine form "gallèse" derives from the Breton , the feminine form of gall. The Trésor de la langue française records several derived variants, including "gallot", "gallec", "gallek", "gallais", "gallic", and "gallou", as well as the feminine "gallote". These terms may refer not only to the language itself, but also to people from Upper Brittany and to cultural features associated with the language and its speakers.

The term gallo was initially used by Breton speakers, which partly explains why it has historically been little used by Gallo speakers themselves. A survey conducted in 1986 by Henriette Walter showed that only slightly more than 4 percent of speakers in the Côtes-d'Armor reported having always used the term, and that about one third of them perceived it as carrying a rather pejorative meaning. According to this survey, the term "patois" was by far the most commonly used designation. Although the word gallo has been attested for a long time, with its first written occurrence dating to 1358, it is therefore largely a relatively recent denomination.

Gallo is also referred to as "langue gallèse" (Gallo language) or "Britto-Romance".

The term "Britto-Romance" was coined in 1978 by the linguist Alan-Joseph Raude to emphasize that Gallo is "a Romance idiom spoken by Bretons". According to him, the designation "patois" is inappropriate because it denotes "an inferior vernacular variety of a language of culture", a concept that is sociological rather than linguistic.

Another linguist, Jean-Paul Chauveau, similarly considers the term "patois" to be generic, as it can be applied to any variety of speech in France that differs from French. In this sense, it "denies any specific identity to the language to which it is applied".

The term "patois" is generally perceived as pejorative, although it may retain an affective or familiar connotation for some Gallo speakers.

Gallo should not be confused with the Gallo-Romans, nor with the term "Gallo-Romance", which refers to the Romance varieties spoken in former Roman Gaul that later gave rise to the Oïl languages, including both Gallo and French. In Breton, until around 1960, the term Gallaoued did not specifically denote the French (Fransizien), but rather local Romance-language speakers, such as inhabitants of market towns who had shifted to French.

Classification Gallo is part of the Oïl languages, a linguistic group that occupies roughly the northern half of France. This group includes a wide range of more or less clearly defined and differentiated varieties that share a Latin origin and a Germanic influence derived from Old Frankish, the language of the Franks. Among the Oïl languages, in addition to Gallo, are Picard, Norman, French (that is, Francien as spoken in Île-de-France and the Orléanais), Poitevin, Champenois, Romance Lorrain, Berrichon, Northern Burgundian, and others.

Gallo, like the other Oïl languages, is neither Old French nor a deformation of modern French. The historical developments are largely shared, including the influence of Frankish on vocabulary and syntax, the loss of the nominative versus oblique case distinction, and the loss of pronunciation of many final letters. Gallo has evolved continuously since the medieval period, and an earlier stage referred to as "Old Gallo" can therefore be identified.

Moreover, because Old French itself was only weakly standardized, medieval writers used terms and constructions characteristic of their own regions. As a result, traces of Old Gallo can be found in medieval writings from Upper Brittany.

The Oïl languages belong to the group of Gallo-Romance languages, which also includes Franco-Provençal, spoken in particular around Savoy. The Gallo-Romance languages are themselves part of the wider group of Romance languages, which also includes, among others, Italian, Spanish, and Romanian. The Romance languages in turn belong to the larger Indo-European language family.

Breton has influenced Gallo through a limited number of lexical borrowings. However, the use of the preposition "pour" as an auxiliary verb has been identified as being of Celtic origin. The relationship between Breton and Gallo has been compared to that between the two languages of Scotland: Scots and Scottish Gaelic.

Geography Linguistic area

The linguistic area of Gallo is difficult to define. To the west, the linguistic boundary of Brittany is clearly identifiable, as it separates a Celtic language from a Romance variety. By contrast, the boundary between Gallo and the other Oïl languages is less clearly defined, owing to the existence of a dialect continuum. Traditionally, the Oïl-speaking area has often been divided according to the limits of historical regions. However, these boundaries do not always correspond to linguistic realities.

Some authors rely on traditional regions to define the Gallo area, while introducing qualifications. Walther von Wartburg, Hans-Erich Keller, and Robert Geuljans conventionally equate the Gallo area with the departmental boundaries of Ille-et-Vilaine and Loire-Atlantique, while adding northern Anjou. likewise restricts Gallo to Upper Brittany, but extends it to the western fringe of Mayenne and Maine-et-Loire. He further groups Gallo, Angevin, Norman, and the varieties of Mayenne and Sarthe into a single set, which he terms the western Oïl languages.

Defining the limits of Gallo is further complicated by a lack of detailed cartography for the central varieties of the Oïl domain. The speech forms of Maine, Touraine, and the Orléanais are situated between Paris and more clearly identified Oïl languages such as Gallo or Norman. These varieties tend to be marginalized and lack a strong linguistic identity. Some scholars therefore consider north-central France to constitute a central zone without clear internal boundaries. In this perspective, Marcel Cohen regarded Maine as an indeterminate area in which Gallo, Angevin, and Orléanais intermingle, and consequently declined to draw boundaries between them.

Marie-Rose Simoni-Aurembou considers Gallo to be an "Oïl variety", comparable to Norman or Poitevin, bordered to the east by a set of "Oïl variations" such as Angevin. According to her, Gallo does not extend beyond the limits of historical Brittany, except in the south, where Poitevin extends northward toward the Loire, without actually reaching it.

Finally, some authors disregard traditional boundaries altogether and rely exclusively on linguistic criteria to define the Oïl languages. Jean-Paul Chauveau, drawing in particular on lexical influences, groups Gallo, Angevin, and Mayennais into a broad area known as the "Pays d'Ouest", which he subdivides into three zones: a western zone including Côtes-d'Armor, Morbihan, and western Ille-et-Vilaine; an eastern zone comprising Sarthe, Mayenne, and eastern Ille-et-Vilaine; and a southern zone including Loire-Atlantique and Maine-et-Loire. This last zone lacks cohesion, as the area north of the Loire aligns more closely with the Mayenne group, while the area south of the river shows Poitevin influence. Chauveau does not define a clear boundary between Gallo and Poitevin, but instead identifies a threshold marked by the Loire.

The languages of Brittany and neighboring regions according to several authors:

Boundary between Gallo and Breton The modern western boundary of Gallo is clearly defined, as it bears no resemblance to Breton. The linguistic frontier between the two languages was compared to the "Great Wall of China" by the historian Pierre-Michel-François Chevalier in 1845. In 1952, traced this boundary between Plouha, on the western coast of the Bay of Saint-Brieuc, and the Pénerf River near the Rhuys Peninsula. Between these two points, he drew the line through Senven-Léhart, Quintin, Mûr-de-Bretagne, Saint-Gérand, Réguiny, and Sulniac.
