_an-zak-ku_ is a verb. _an_ is an indeterminate verbal prefix. The context shows it to be of the second person (see MSL. p. XXVI). _zak-ku_ may mean “utter a decree” (Br. 6519). For example, _zak_ equals _tamîtu_, “a decree” (Br. 6493). Perhaps it could as well be a verb signifying “to decree”, or “to establish”. _ku_ also equals _tamû_, “utter” (Br. 10555), but it would be simpler to make _ku_ a phonetic complement to _zak_. It may be that we ought to read the clause: “thy name utters the decree”. But “thy name” has the usual position of the object. It is also rather awkward to regard _zak_ as an object placed between the verbal prefix and the verb. 2. _^dimmer Mer bi-maḥ ḥad-ê-a mu-zu an[-zak-ku]_ O Adad, in the mighty thunder and the lightning flash thou declarest thy name. _^dimmer Mer_: this is the Sumerian name of the storm-god. _Mer_ being one of the values of the sign IMMU. The fact that the sign in some cases in this hymn (e. g. lines 15 and 17) is followed by the phonetic complement _ri_ or _ra_ shows that _Mer_ is the value intended for the name of the god. _Mer_ is probably from _imi_ changed to _immer_ and then to _Mer_ and hence, like _imi_, means “wind” and “storm”. The name _Mer_ offers no suggestion as to the origin of the Semitic names _Rammânu_ and _Addu_. _bi-maḥ_ equals “mighty utterance”. _bi_ (see Hymn to Sin, line 13). _maḥ_ (see Hymn to Bêl, line 23). _ḥad-ê-a mu-zu an-zak-ku_ (see on line 1). 3. _[^dimmer] Mer dumu An-na bi-maḥ ḥad-ê-a mu-zu an-sa[k-ku]_ O Adad, son of Anu, in the mighty thunder and the lightning flash thou declarest thy name. _dumu_ (see Hymn to Sin, line 5, _ṭu-mu_). _An-na_, ideogram for the god of heaven, plus phonetic complement. Note that AN for the god Anu does not take the determinative god sign. Probably the omission is due to the desire to avoid the occurrence of AN twice in succession. It must have been after Adad had taken the place of Ištar in the second triad of gods that Adad was called the son of Anu. The earlier arrangement was Anu, Bêl, Ea, Sin, Šamaš and Ištar. The later order was Anu, Bêl and Ea, as rulers of the universe, and Sin, Šamaš and Adad, as rulers of heaven under the command of Anu. This new grouping was the result of a theological development. Ištar was found to be one of the planets, and, therefore, not to be classed longer along with Sin and Šamaš. Adad, the god of the atmosphere, was thought to be a personality of sufficient dignity to take the place formerly occupied by Ištar. _bi-maḥ ḥad-ê-a mu-zu an-zak-ku_ (see on lines 1 and 2). 4. _ù-mu-un nì-ki-ge bi-maḥ ḥad-ê-a mu-zu an-zak[-ku]_ O lord, dread of earth, in the mighty thunder and the lightning flash thou declarest thy name. _ù-mu-un_ (see Hymn to Bêl, line 1).
