From the root ش ح ذ (š ḥ ḏ). According to Vollers the meaning “to beg” (in Vulgar Arabic often with د (d) and ت (t) for the last consonant) is contaminated from Aramaic שְׁחַד / ܫܗܰܕ (šḥaḏ, “to gift, to bribe”), but Brockelmann deems such a connection impossible as beggars are not bribed and in turn it denotes what they do.
