A main characteristic of Rashi's writing was his focus on grammar and syntax. His primary focus was on word choice, and "essentially acts as a dictionary where he defines unusual Hebrew words." He searches for things that may not be clear to the reader and offers clarification on the inconsistency that may be present. Rashi does so by "filling in missing information that lead to a more complete understanding" of the Torah. Rashi focused the majority of his responsa, if not all, on a "meticulous analysis of the language of the text." A portion of his writing is dedicated to making distinctions between the peshat, or plain and literal meaning of the text, and the aggadah or rabbinic interpretation. One of Rashi's grandchildren, Rabbi Samuel B. Meir or Rashbam, heavily critiqued his response on his "commentary on the Torah [being based primarily on the classic midrashim (rabbinic homilies)."
