ŠaŠa Ša The cuneiform ša sign is a common, multi-use sign, a syllabic for "ša", and an alphabetic sign used for "š", or "a"; it is common in both the "Epic of Gilgamesh" over hundreds of years, and the 1350 BC Amarna letters. Besides "ša" usage in word components of verbs, nouns, etc., it has a major usage between words. In Akkadian, for English language ""who"", it is an interrogative pronoun; in the Akkadian language as "ša", (as "that", "what"; ("that (of)", "which (of)"), in English it used for "who, what, which, etc.". Ša, and Ka, the stroke differences. The  difference in the construction of the signs "ka" and "ša" are as follows: "ka" when scribed in the Amarna letters often shows the distinctiveness of the right section of the sign, versus the left section. For "ša", the right section is constructed with two wedge strokes (one scribed above the other), between the two verticals, at right. For "ka", the right side mostly, in the Amarna letters has two verticals, with two horizontals that cross both of them; (the right side is like a two-step ladder shape—(for Hittite "ka":—)). A good example of "ša", is shown for EA 365 , Reverse (top half), where the 2-wedge strokes of "ša" between the 2-right verticals is clear. (Note, the "ša" of EA 365 appears to have 3-horizontals at left (differing lengths), then the 2-verticals with the 2-wedge strokes, at right.) Ša Usage numbers. Section::::"Epic of Gilgamesh". The usage numbers for "ša" in the "Epic of Gilgamesh" are as follows: "ša"-(66) times. There are no other sub-uses or sumerogramic uses for "ša" in the "Epic of Gilgamesh". Amarna letters. Cuneiform "ša" is common in the Amarna letters, found easily between words (as the pronoun), and especially in  word constructs. Since it is similar in appearance to cuneiform "ka", the large difference is that "ka" can easily be found as a suffix to words, for example in the Canaanite sub-corpus of letters as ""Servant-Yours"", , ("ARAD-ka").
