The lexicons unanimously separate two roots: ענן I, denominative from עָנָן "cloud" and attested only at Genesis 9:14, and ענן II "practise soothsaying, conjure" in ten Poel forms. BDB (1906, 778) reports the old derivation of the divination verb from "cloud" as "now generally abandoned", crediting Delitzsch on Isaiah 2:6; DCH VI (2007, 501-502) and Gesenius 18 (2013) list the two as distinct lemmata; NIDOTTE and TWOT 1655 concur while admitting that "the exact nature of this soothsayer's practice is unknown". HALOT sets out four etymological options without choosing: denominative cloud interpretation (Dalman, Reymond); Arabic ʿanna "to appear" (Kopf, VT 8: 190, adopted by Klein); Arabic ghanna "to hum, buzz", hence fortune-telling in a quiet droning voice (Robertson Smith 1885); and Ugaritic ʿnn "to recite spells" (Albright, Yahweh and the Gods of Canaan, 107). Freedman, Willoughby and Fabry in TDOT 11:253-274 follow the same typology, note that ancient tradents themselves associated the verb with עוֹנָה "season" (whence the KJV "observer of times"), and, with G. Andre, flag the imperfect ghayin/ayin correspondence between Arabic and Hebrew as leaving the etymology unresolved. Among commentators the Robertson Smith "muttering enchanter" reading now has the widest support (Tigay, Milgrom, Jeffers, Schmitt, Paul), buttressed by the fixed pairing with נחשׁ, the parallel of Isaiah 8:19 (הַמְצַפְצְפִים וְהַמַּהְגִּים), and LXX Micah 5:11 ἀποφθεγγόμενοι; Levine (JPS Leviticus, 133) is the notable recent holdout for an atmospheric-sign reading, and Cryer (JSOTSup 142) cautions against reifying the polemical vocabulary into distinct guilds at all. The versional evidence is itself a datum: LXX renders variously κληδονιζόμενος, ὀρνιθοσκοπήσεσθε, ἀποφθεγγόμενοι, and at Judges 9:37 splits between δρυὸς ἀποβλεπόντων (A) and a transliterated Μαωνενιμ (B), while Jerome standardizes on augur and the Peshitta collapses ענן into קסם, showing the technical sense had already lapsed by the Hellenistic and Roman periods. None of the ancient versions supports the cloud-diviner reading. Sociologically the practitioner belongs to a West Semitic guild of mantic specialists attested from Philistia to Transjordan (Isaiah 2:6; Jeremiah 27:9; Blenkinsopp, Wildberger, Holladay, Lundbom), stereotyped in the Deuteronomistic regnal notices of Manasseh (Cogan and Tadmor, II Kings, 266-267), and plausibly localized at the Shechem sanctuary complex by the אֵלוֹן מְעוֹנְנִים of Judges 9:37.
