ḳiria - accidental pollution (MD 412)

ḳiria ḏ-lilia ‘pollutio nocturnis’ (ibid.)

PS
*ḳry/ˀ - to have effusion (menstruation, pollution) (SED I No. 37v)
Alternatively, a nominal root *ḳVry/ˀ­ ‘effusion (menstruation, pollution)’ can be reconstructed, the related verbal forms to be then considered denominal.
