The classical Milanese orthography is the orthography used for the Western Lombard language, in particular for the Milanese dialect, by the major poets and writers of this literature, such as Carlo Porta, Carlo Maria Maggi, Delio Tessa, etc. It was first used in the seventeenth century by Carlo Maria Maggi; Maggi first introduced the trigram oeu, while previous authors, like Bonvesin de la Riva (thirteenth century), used Latinizing orthographies. In 1606 G. A. Biffi with his Prissian de Milan de la parnonzia milanesa began the first codification, incorporating vowel length and the use of ou to represent the sound /œ/.[1] The classical orthography came as a compromise between the old Tuscan system and the French one; the characteristic that considerably differentiates this orthography from the effective pronunciation is the method for the distinction of long and short vowels. As of today, because it has become more archaic, it is often replaced by simpler methods that use signs ö, ü for front rounded vowels and the redoubling of vowels for long vowels. The classical orthography was regularized in the 1990s by the Circolo Filologico Milanese for modern use.
