Esther 1:20, Question 2. Why does the verse use the Aramaic words, “pisgam” and “yikar?”

The Talmud (Megillah 9a) cites this verse’s two Aramaic words in a discussion regarding a holy text becoming invalid if even one of its non-Hebrew words is substituted by a Hebrew equivalent by the sofer writing it. As a class participant, KL, pointed out, this strongly indicates that Megillas Esther is holy and TaNaCh-worthy (see Introduction).
