Most of the examples of abbreviations in the Gemara are to phrases in Aramaic. Why would the Torah hint to aramaic phrases?
The Sages teach that the language of Aramaic is rooted in Hebrew, but that the Hebrew became corrupted. A number of commentators (such as Sefer Targum Avraham by the son of the Vilna Ga'on) have shown the Hebrew source for every Aramaic word used by Targum Onkelos.
(See also what we wrote in the Insights to 77b in the name of the Maharsha and Tiferes Yisrael regarding the Gemara there that says that certain Aramaic words are contractions of Hebrew words.)y
