A difficult to interpret fragmentary text, KBo 24.29+ III 6'-7', uses a derivative of the term istarna-, "middle", to describe Ḫuwaššanna's character, though it is not certain what her status as a "middle spirit" entailed. Hans Gustav Güterbock proposed that Ḫuwaššanna might have functioned as an "irate deity", though there is no indication in known texts that she was believed to disappear when angered, in contrast with gods such as Telipinu.
