Onomastic analysis has also been brought to bear on the question. The place name "Dimallum" belongs to the southeast Dalmatian onomastic area of Illyrian. Onomastic analysis has suggested that Nabataean culture may have had multiple influences. Some Iberian onomastic elements have look-alikes in Aquitanian or Basque. "Balamir" has the Gothic onomastic suffix "-mir/-mer". There are several published onomastic dictionaries in Azerbaijani including more than 15.000 names.
