Grecicize

1894, H.E. Wassa Pasha and P. Colquhoun, "The Pelasgi and their Modern Albanian Descendants", in The Imperial and Asiatic Quarterly Review and Oriental and Colonial Record, New Series, Vol. VII, No. 13, The Oriental University Institute, Woking. Interesting too is the contention, that after the Pelasgi had occupied Asia Minor and the islands in the Aegean Sea, they conquered Greece, became gradually grecicized, and then, from Greece, re-conquered their original settlements, which in the meanwhile had themselves become grecicized.

1951, Karl Heinrich Menges, "The Oriental Elements in the Vocabulary of the Oldest Russian Epochs", in Word: Journal of the Linguistic Circle of New York (Supplement). From Byzantine sources, the word is rather late as τζελεπἡς (usually grecicized and declined, explained as ἑξ εὐγενῶν καταγὁμενος), in the main found with Georgios Frantzes (Γεὠργιος Φραντζἠς, 1401–1478[?]) treating the history of 1258–1477...

Of course, Byzantines who were engaged in legal parlance would have encountered the grecicized "ἀκτοριτάτε" (occasionally used in legal texts) and its later trajectory in Romance vernacular.

They comprised a number of Greeks from Istanbul, and a number of grecicized Romanians.
