Cuneiform hal has a single usage in the Epic of Gilgamesh, for hal. The usage is: hal, 11 times. In the Epic of Gilgamesh, the most common usage of hal, at the beginning of words spelled "hal-" in the glossary, is for Akkadian halāqu, English, to disappear, to cause to be lost; in the Amarna letters it is used to refer to city-states, or towns, lost to the Hapiru. In the Epic, two other words use hal at the beginning of their spellings, halbu, for English forest, three times in the Epic, Tablets VII, IV, and II. One spelling of halāpu, (English, "to clothe"), of four spellings, uses hal, Tablet IV, line 196, ú-hal-lip. Amarna letters usage
One main usage in the Amarna letters, is for the Akkadian language word halāqu, referring to the capturing of city-states, or towns, (Amarna letter EA 288). References
