Kloekhorst 2008:518 argues for a *-mn̥ derivative of the root *h₃neh₃- (“to name”), reflected in Hittite [script needed] (ḫannai-, “to sue, judge”) (originally "to call to court") and Ancient Greek ὄνομαι (ónomai, “to blame, scold, insult”) (with a semantic shift comparable to English to call names); see also *h₃en(h₂)-.
Sources disagree on the reconstruction of this word. Some reconstruct it with initial *h₃- because of Greek ὄνομα (ónoma), ὄνυμα (ónuma) and (ἀ)νώνυμος ((a)nṓnumos) (*n̥h₃C>νωC), but the lack of an initial laryngeal in Hittite 𒆷𒀀𒈠𒀭 (lāman) might suggest *h₁ (although the fate of word-initial *h₃ in Anatolian is unclear and controversial), and Armenian անուն (anun) could be from either one. The Greek o- could be due to assimilation to the following o-, just as in ὀδούς (odoús, “tooth”), from *odonts, assimilated from *edonts, from *h₁dont-, although this is now reconstructed with *h₃ by some authorities. Medial *-eh₃- is sometimes reconstructed on the basis of length in some Dutch and Low German denominal verbs, but these are more likely to be late forms using the Germanic a/ō ablaut found also in class VI strong verbs (and in Indo-Iranian it could have arisen by Brugmann's law, and in Latin by the analogy co-gnōscō (“to know”) : cōg-nōmen (“surname”) = nōscō (“to know”) : nōmen, with the other forms from PIE *ǵneh₃-).
The original paradigm is also somewhat difficult to reconstruct precisely; it might be proterokinetic ablauting *h₁nómn̥ ~ *h₁n̥méns, or just acrostatic with or without zero grade in weak cases. The Tocharian forms seem to come from *(h₁)nem-, which could be from the oblique form in an acrostatic paradigm. However, Ronald Kim reconstructs Proto-Tocharian *ñemə as *h₁nḗh₃mn̥.
