According to Henning 1944, 117, Syr. bwrsmʾ and Off. Aram. brzmdnʾ are connected with OP *barzman- and not with OP *brazman-, cf. *brazmadāna- (Median), as suggested by Hinz 1975, 67. Henning holds that we have "two different stems, which are distinguished by their meaning and by the position of the guṇa-vowel", namely a) form, style, ceremony, rites: OP *brazman-, MP brahm(ag) form, manner, costume (CPD 19), OInd. bráhman- etc.; b) bundle of twigs, bed of grass, pillow: OP *barzman-, Av. barəsman-, MP barsom, etc.
