Hebrew and Aramaic are languages of Jewish sefarim (religious books) and it is forbidden to learn/read sefarim during Tisha B Av because it gives joy to man to do so.
Is it then likewise forbidden to learn Hebrew/Aramaic in order, during Tisha B Av, to get a better understanding of sefarim in the original, considering that the reason for doing so is connected with learning (talmud torah), which is forbidden?
