'aramaicize' originates from the English adjective 'Aramaic' plus the productive suffix '-ize', ultimately from Greek '-izein' (through Latin/French), where the suffix meant 'to make or to do'.

'Aramaic' itself comes from Greek 'Aramaios' (Ἀραμαῖος) referring to the Arameans or their language, which in turn reflects the Semitic name 'Aram' for a region/people; the English verb was formed by combining the modern English adjective with the Greek-derived verbalizing suffix '-ize' to produce 'aramaicize'.

Initially the components meant 'pertaining to Aram/Aramaic' (Aramaic) and 'to make or do' (-ize); combined in English they came to mean 'to make or render into Aramaic'.
