古アイルランド語では''Óengus''または''Oíngus''（oiŋɡus）といい、アドムナン（Adomnán）の『聖コロンバの生涯』では''Oinogus（s）ius''として記載されている<ref>Adamnan, Reeves, William, Life of Saint Columba, Founder of Hy, 1874, Edmonston and Douglas, Edinburgh, [https://archive.org/details/bub_gb_8VULAAAAYAAJ/page/n307 123], https://archive.org/details/bub_gb_8VULAAAAYAAJ, 18 January 2018</ref>。これは、「真の活力（true vigour）」を意味するプロト・ケルト語の名前に由来すると考えられている<ref name="mythlegendromance"/>。中世のディンセンチャス（''Dindsenchas''）は「一つの望み」に由来し、ボアンがダグダとの結婚を唯一の望みとしたため、この名前をつけたと説明している<ref name="Boand_II">Stokes, Whitley, The Metrical Dindsenchas: Boand II, https://celt.ucc.ie/published/T106500C.html, Corpus of Electronic Texts, University College, Cork, 3 August 2019}}</ref>。

In [[Old Irish]] his name is ''Óengus'' or ''Oíngus'' {{IPA-sga|ˈoiŋɡus|}}, a name attested in [[Adomnán]]'s ''Life of St Columba'' as ''Oinogus(s)ius''. This is believed to come from a [[Proto-Celtic]] name meaning "true vigour". The medieval ''Dindsenchas'' derives it from "one desire", explaining that Boann gave him the name because her union with the Dagda had been her only desire.<ref name="Boand_II">{{cite web |last1=Stokes |first1=Whitley |title=The Metrical Dindsenchas: Boand II |url=https://celt.ucc.ie/published/T106500C.html |website=Corpus of Electronic Texts |publisher=University College, Cork |access-date=3 August 2019}}</ref> In Middle Irish this became ''Áengus'', and in [[Irish language|Modern Irish]] ''Aonghus'' {{IPA-ga|ˈeːŋɡəsˠ|}}, {{IPA-ga|ˈeːŋɣəsˠ|}}.
