Morríganはしばしば三つ組の女神とされるが、この三つ組は曖昧で一貫性がない。このように三つ組に見えるのは、ケルトの「緑」の意味もある<ref name=":0" />。エルンマスの娘である三姉妹の一人として登場することもあるし、

The Morrígan is often considered a [[Triple deities#Triple goddesses|triple goddess]], but this triple nature is ambiguous and inconsistent. These triple appearances are partially due to the Celtic significance of [[3#Religion|threeness]]. Sometimes she appears as one of three sisters, the daughters of [[Ernmas]]: Morrígan, [[Badb]] and [[Macha (Irish mythology)|Macha]].<ref name="Invasions">{{cite book | author=Macalister, R.A.S. (trans.) | title =Lebor Gabála Érenn: Book of the Taking of Ireland Part 1-5 | publisher = Irish Texts Society | year =1941 | location =Dublin}}</ref> Sometimes the trinity consists of Badb, Macha and Anand, collectively known as the ''Morrígna''. Occasionally, [[Nemain]] or [[Nemain|Fea]] appear in the various combinations. However, the Morrígan can also appear alone,<ref name="CELT-Regamna"/> and her name is sometimes used interchangeably with Badb.<ref name="CMT166-CELT"/>
The Morrígan is mainly associated with war and fate, and is often interpreted as a "war goddess". [[W. M. Hennessy|W. M. Hennessy's]] ''The Ancient Irish Goddess of War'', written in 1870, was influential in establishing this interpretation.<ref>[[W. M. Hennessy]], [http://www.sacred-texts.com/neu/celt/aigw/index.htm "The Ancient Irish Goddess of War"], ''[[Revue Celtique]]'' 1, 1870–72, pp. 32–37</ref> She is said to derive pleasure from mustered hosts.<ref>{{Cite web|url=https://celt.ucc.ie//published/T106500D/text049.html|title=Part 49 of The Metrical Dindshenchas|website=celt.ucc.ie}}</ref> Her role often involves premonitions of a particular warrior's violent death, suggesting a link with the [[banshee]] of later folklore. This connection is further noted by [[Patricia Lysaght]]: "In certain areas of Ireland this supernatural being is, in addition to the name banshee, also called the ''badhb''".<ref>{{cite book |first=Patricia |last=Lysaght |title=The Banshee: The Irish Death Messenger |year=1986 |isbn=1-57098-138-8 |page=15}}</ref> Her role was to not only be a symbol of imminent death, but to also influence the outcome of war. Most often, she did this by appearing as a crow flying overhead, and would either inspire fear or courage in the hearts of the warriors. In some cases, she is written to have appeared in visions to those who are destined to die in battle as washing their bloody armor. In this specific role, she is also given the role of foretelling imminent death with a particular emphasis on the individual.<ref>{{Cite book |title=Celtic Myths and Legends |last=Rolleston |first=T.
