モリガンの名前の意味には異論もある。

''Mor'' may derive from an [[Indo-European languages|Indo-European]] root connoting terror, monstrousness [[cognate]] with the [[Old English]] ''maere'' (which survives in the modern English word "nightmare") and the Scandinavian ''[[mare (folklore)|mara]]'' and the [[Old East Slavic]] "mara" ("nightmare");{{sfn|DIL|1990|pp=467–468}} while ''rígan'' translates as "queen".{{sfn|DIL|1990|p=507}}<ref name="maryjones.us">[https://www.maryjones.us/jce/morrigan.html Jones Celtic Encyclopedia Entry: ''Morrigan'']</ref> This etymological sequence can be reconstructed in the [[Proto-Celtic language]] as *''Moro-rīganī-s''.<ref>{{cite web |url=http://www.st-andrews.ac.uk/institutes/sassi/spns/ProtoCelt.pdf |title=Proto-Celtic – English wordlist |archive-url=https://web.archive.org/web/20070927041947/http://www.st-andrews.ac.uk/institutes/sassi/spns/ProtoCelt.pdf |archive-date=27 September 2007}}</ref><ref>{{cite web |url=http://www.etymonline.com/index.php?term=nightmare |work=EtymologyOnline |title="nightmare"}}</ref> Accordingly, ''Morrígan'' is often translated as "Phantom Queen".<ref name="maryjones.us"/> This is the derivation generally favoured in current scholarship.{{sfn|Clark|1990}}
