A hypothetical verbal element in the participle adjective zabathân “humbled” (SD/247). According to Andreas Moehn (EotAL/ZAB’TH), Aleš Bičan suggested that the initial element za- is some kind of verbal prefix, similar in function to nu- in ᴹQ. nukumna “humbled”, which would help explain why it does not undergo the Adûnaic syncope in its participle form.
* zabath-verb. to (be) humble
