Venetan belongs to the group of northern Italian dialects, which are characterized by the presence of some phonological and morphological features that are common to French dialects and are attributed to the Celtic substratum. However, numerous traces of the Venetic substratum distinguish the Venetan dialects from the other (Gallo-Italic) dialects.
In the linguistic history of the Venetan dialects, Venice played a central role due to the political power achieved by the Venetian Republic and its commercial expansion into many Adriatic and Mediterranean countries. There, the Venetian dialect laid the foundations for the development of a “colonial Venetian,” which has been used for several centuries.
In the 21st century, Venetan is still vital in three regions of northeastern Italy (Veneto, Trentino Alto-Adige, Friuli Venezia Giulia), in Istria, and in Dalmatia. Small Venetan-speaking communities are also found elsewhere in Europe as well as Canada, Australia, and North and South America. These were the destination countries for the numerous emigrants who left Veneto between the end of the 19th century and the first half of the 20th century.
Alongside several structural features that are common to the other northern Italian dialects, Venetan presents some distinctive properties. In phonology, apocope and syncope are restricted and consonant lenition in inter-vowel position is extensive. In verbal morphology, Venetan is characterized by the agglutination of the auxiliary ‘have’ with the clitic ghe, the alternation of the traditional Venetian form [ze] with the form [ɛ] for the auxiliary ‘be’ at present indicative 3rd persons, and the variety of past participle suffixes. In nominal derivation, some suffixes, such as the augmentatives -ón/-óne and -àso and the present participle suffix -ànte (which is used for the formation of nomina agentis) are very productive. In syntax, 2sg and 3sg/pl subject clitics are obligatory; dative and object clitics are used for doubling respectively datives and pronominal objects in the 1st and 2nd person; specific rules govern the structure of direct, indirect, and noncanonical interrogatives. The Venetan lexicon, which developed in several domains, particularly in marine (on the lagoon) and agricultural (on the mainland) contexts, mirrors the history of the region, revealing several traces of different strata (Celtic, Germanic, Greek, Slavic, Jewish, and French).
