[6] Archaeologist Géza Nagy derived Kál's name from the Turkic verb kal ("stay"), accepted this theory by linguist Dezső Pais.
[7] Byzantinist Mátyás Gyóni claimed that the name Kál means Khalyzian, thus Constantine's work misunderstood Bulcsú's narration and reflected to his ethnicity.
[9] As a combination of the narrations of Constantine and Anonymus, László Makkai claimed that initially Bogát, himself possibly a son of Tétény, served as harka until he was elevated to the dignity of gyula which resulted his settlement from the western part of the Carpathian Basin to Transylvania in the early 920s.
[10] According to György Szabados, this information reflects the statehood-nature of the Principality of Hungary and the title of harka was a hereditary position (at least in the relation of Kál and Bulcsú).
[12] Continuing west, Kál established his winter residence in present-day Dióskál (at Little Balaton), which laid near the Carolingian fort Mosaburg (Zalavár).
Kál's tribe advanced north along the river Zala, reaching the Rába valley along Lake Neusiedl (Fertő) and the area of Szombathely.
According to Györffy, these are the linguistic memories of the temporary residence areas where Bulcsú's tribe initially seized during the first stage of the Hungarian conquest.
