Comasco (endonym: comasch), anglicized as Comasque, is a dialect belonging to the Western branch of Lombard language, spoken in the city and suburbs of Como.
In ancient times, the Lake Como area was inhabited by Orobi, Leponzi, and Etruscan tribes.
In Roman times, the Latin spoken in the Lake Como area was influenced by the Celtic substratum, contributing to the phonetic and lexical formation of today's dialect.
In the early Middle Ages, the area was occupied by the Lombards, who probably spoke a dialect of the Saxon language and brought a further, albeit small, lexical contribution.
In the late Middle Ages, the Lake Como territory became part of the Duchy of Milan.
