...In his classic style, the Pri Megadim emphasizes for us the importance of being fluent in both Hebrew and Aramaic grammar, not merely as a subject of its own, but as an integral part of properly translating and understanding Gemara.

Being familiar with the language is not only helpful in understanding Gemara but also ensures that the learner will retain his knowledge. As the Gemara tells us:

"The people of Yehudah who are precise in their language (i.e., they were careful to express themselves with the proper words), (therefore) their Torah was retained in their hands."
