The cuneiform ha sign comes in two common varieties in the 1350 BC Amarna letters.
It is also found in the large 12-chapter (Tablets I-XII) work of the Epic of Gilgamesh.
Cuneiform ha is used as a syllabic for ha, and an alphabetic for h, or a; from the Epic of Gilgamesh it also has two sumerogramic uses (capital letter (majuscule)), for HA (Akkadian language zittu, for "share"), and KU6, for nūnu, "fish".
[3] The digitized version of ha has 4, short vertical strokes, 2-pairs-of-2, in a square; it is ligatured at the right, typically with a large, or medium-large sized wedge-stroke.
In the Epic of Gilgamesh the usage numbers for the ha sign is as follows: ha-(145 times), HA-(2), KU6-(4).
