'Aramaicism' originates from Modern English, formed from 'Aramaic' + the suffix '-ism', where 'Aramaic' ultimately refers to the language of the Arameans.

'Aramaic' comes into English via Latin and Greek (Greek 'Aramaîkós') from the name of the Arameans (Hebrew 'Aram'), and '-ism' is a productive English suffix forming nouns indicating doctrine, practice, or characteristic. These combined in Modern English to form 'Aramaicism'.

Initially, related forms simply named the Aramaic language or the Arameans; over time 'Aramaicism' came to mean specifically a linguistic feature or influence traceable to Aramaic.
