ˁassäwä - essere malarico, di luogo paludoso ecc. che produca la febbre (to be malarial, swampy, etc. get ill with fever) (TED 1861, Bassano 1918: 684)

PS
*ˁaw/yš-, *ˁašw/y- - kind of disease (fever, cold in the head; plague) (SED I No. 27)
The Akk. variant form with ḫ- may also suggest γ-. The ESA and Jib. forms, however, clearly point to ˁ-.
