Arameism

Formed in English from Aramean +‎ -ism by swapping -an with -ism.

Arameism (countable and uncountable, plural Arameisms)

1. (hypercorrect, rare) Alternative spelling of Aramaeism, misconstruction of Aramaism
   • 1828, Wilhelm Gesenius, translated by Christopher Leo, A Hebrew Lexicon to the Books of the Old Testament, volume 2, Cambridge: University Press, page 598b:

     […] but in an Arameism of this kind the form is always preserved with the signification, which is not the case, for in Aram. the conj. Aphel only is in use.

The suffix -aeismus (or -æismus) is a hypercorrect form not attested in Classical Latin, as it would imply a Greek -αϊισμός (-aïismós), which does not exist. Greek formations use -αϊσμός (-aïsmós) instead, Latinized as -aismus: e.g. Ancient Greek Ἰουδαϊσμός (Ioudaïsmós) (Latin iudaismus), from Ancient Greek Ἰουδαῖος (Ioudaîos) (Latin iudaeus).
