== 名前 ==
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、ボアーンが[[ダグザ]]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>。。中世アイルランド語ではÁengusとなり、現代アイルランド語ではAonghus(ˈeːŋɡəsˠ、ˈeːŋɣəsˠ)となった。
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. In Middle Irish this became ''Áengus'', and in [[Irish language|Modern Irish]] ''Aonghus'' {{IPA-ga|ˈeːŋɡəsˠ|}}, {{IPA-ga|ˈeːŋɣəsˠ|}}.
He is also known as ''Óengus Óc''/''Aengus Óg'' ("Aengus the young"), ''Mac ind Óc'' ("son of the young"), ''Maccan''/''Macán'', or ''Mac Óc/Mac Óg'' ("young son").<ref name="mythlegendromance"/>
