When To Say It In Aramaic

The Gemara (Pesachim 87b) offers numerous explanations as to why Hashem chose Bavel as the destination for the exile. One such explanation is that the language spoken in Bavel, Aramaic, was most similar to Hebrew. The similarity of the languages would make it easier to study Torah and ensure that Torah would not be forgotten.
Why is there a similarity between Aramaic and Hebrew? The sefer Chasdei Hashem authored by R’ Mordechai Kriger offers a novel explanation. Before the building of the tower of Babylon, the people of the world shared a common language: Lashon HaKodesh. As a punishment for their futile attempt to rebel against Hashem, Hashem caused them to speak 70 different languages. R’ Kriger theorizes that the first new language that Hashem created was Aramaic since it was destined to be used in that very location. Since it was the first new language, it was the most similar to the previously used one, Hebrew. The successive new languages were progressively different. (Obviously, Hashem could have done exactly the opposite, but this reasoning suggests that Hashem limited the successive creation of new languages just enough to cause issues. As Rashi notes on Chumash, the languages had similar words but they had different meanings.)
