See also s.v. hdr for the regular form of this verb in Babylonian and occasionally in some other Jewish dialects (and Syriac magic), while the proper assignment of Mandaic HDR is of course impossible, but the regularity of the from with heh in JBA suggests that it belongs there.
In the expression ܟܕ ܚܕܪ, etc., the verb can agree in gender and number with either the surrounding or surrounded element, as illustrated by the citations.
