The hydronym Bunë via which Slavic Bojana emerged, is often seen as indication that Albanian was spoken in the pre-Slavic era in southern Montenegro. Drin is a river in northern Albania, Kosovo and North Macedonia. Similar hydronyms include Drino in southern Albania and Drina in Bosnia. It is generally considered to be of Illyrian origin. Durrës is a city in central Albania. It was founded as an ancient Greek colony and greatly expanded in Roman times. It was known as Epidamnos and Dyrrhachion/Dyrrhachium. Dyrrhachium is of Greek origin and refers to the position of the city on a rocky shore. The modern names of the city in Albanian (Durrës) and Italian (Durazzo, ) are derived from Dyrrachium/Dyrrachion. An intermediate, palatalized antecedent is found in the form Dyrratio, attested in the early centuries AD. The palatalized /-tio/ ending probably represents a phonetic change in the way the inhabitants of the city pronounced its name. The preservation of old Doric /u/ indicates that the modern name derives from populations to whom the toponym was known in its original Doric pronunciation. The initial stress in Albanian Durrës presupposes an Illyrian accentuation on the first syllable. Theories which support local Illyrian-Albanian continuity interpret Durrës < Dyrratio as evidence that Albanian-speakers continuously lived in coastal central Albania. Other theories propose that the toponym doesn't necessarily show continuity but can equally be the evolution of a loanword acquired by a Proto-Albanian population which moved in the city and its area in late antiquity from northern Albanian regions. Epidamnos is the oldest known name of Durrës and it is the first name under which the ancient Greek Corinthian colony was known. It is widely considered to be of Illyrian origin, as first proposed by linguist Hans Krahe, and is attested in Thucydides (5th century BC), Aristotle (4th century BC), and Polybius (2nd century BC). Etymologically, Epidamnos may be related to Proto-Albanian *dami (cub, young animal, young bull) > dem (modern Albanian) as proposed by linguist Eqrem Çabej. Erzen is a river in central Albania. It derives from Illyrian Ardaxanos (*daksa "water", "sea") found in Daksa and the name of the Dassareti tribe. Ishëm is a river in central Albania. It is recorded as Illyrian Isamnus in antiquity. Albanian Ishëm derives directly from Isamnus and indicates that its ancestral language was spoken in the area. Mat is a river in northern Albania. It is generally considered to be
