Akkadian
diˀu - a grave disease characterized by a headache
(CAD D 165, AHw. 174)
Cf. damû ‘to suffer from convulsions’ SB (CAD D 80, AHw. 166), dimītu ‘a disease (paralysis, dizziness (?), poisoning of the flesh’ CAD D 143. Though *VwV > VmV is normal for this period, these forms may also go back to the root *dmw/y (see *dwm ‘to be giddy; have pain in the head’, SED I No. 11v).
Unlike other MSA forms (like Mhr. adōwi ‘to give medicine’, JM 76) the Jib. term cannot be qualified as Arabism for certain, since there seems to be no derived form in -t in Arabic.
