mušērittu - gullet (CAD M₂ 267)

Occuring only in combination with urˀudu, this word is understood as a š-participle from warādu ‘to go down’ by both dictionaries, but is rather a continuation of the present root rebuilt by popular etymology.

*warīd- - (jugular) vein, trachea (SED I No. 287; Kogan 2015:381)
