Macaronian

Introduction (Internal History)
Macaronian (Macaronian: Lígve Macaronyane) is a Romance language spoken in Madeira Islands and Azores Islands (part of Macaronesia, hence the name), brought by immigrants from Iberia to Madeira in 2nd century AD, and to Azores by another wave in around 500-700 AD. It is usually classified as a Italo-Western language but some scholars placed it under a separate branch of Romance, or even grouped it with Sardinian as Southern Romance.

Due to the substrate languages spoken in both archipelagoes, sometimes under the term of "(the hypothetic) Atlantic family", Macaronian has some unique properties among Romance languages, such as ergative alignment, and its over-simplification of consonant clusters. Similar to Sardinian, G and C did not undergo palatalization before I and E, and voiceless consonants are voiced between vowels. Lexically, due to contacts with Iberia and North Africa, there are some features (including lexicon) shared by Ibero-Romance and words of Berber and Phoenician origin.
