 The first systematic scholarly treatment of the modern Greek dialects took place after the middle of the 19th century, mainly thanks to the work of the prominent Greek linguist Georgios Hadjidakis.The absence of descriptive accounts of the speech of individual regions made the efforts of the researchers of the 19th century more difficult.Therefore, the dialects' forms are known to us only during their last phase (from the middle of the 19th century, and until the panhellenic dominance of the Standard Modern Greek).
