It is doubtful that such large number could have been transplanted into Greece in the 9th century; thus there surely had been many Greeks remaining in Greece and continuing to speak Greek throughout the period of Slavic occupation.
On kaheldav, et selline suur arv oleks võidud siirata Kreekasse 9. sajandil; seega jäi kindlasti palju kreeklasi Kreekasse ja jätkas kreeka keele kõnelemist läbi kogu slaavi okupatsiooni perioodi.
