In [[Irish mythology]], the '''Badb''' ([[Old Irish]], {{IPA-sga|ˈbaðβ|pron}}), or in [[Irish language|Modern Irish]] '''Badhbh''' ({{IPA-ga|ˈbˠəu}}, {{IPA-ga|ˈbˠəiw|Munster}})—also meaning "[[crow]]"—is a [[war goddess]] who takes the form of a crow, and is thus sometimes known as '''Badb Catha''' ("battle crow").<ref name="eDILbadb">http://www.dil.ie/5114 ''badb'', Author: [[Royal Irish Academy]]</ref> She is known to cause fear and confusion among soldiers to move the tide of battle to her favoured side. Badb may also appear prior to a battle to foreshadow the extent of the carnage to come, or to predict the death of a notable person. She would sometimes do this through wailing cries, leading to comparisons with the [[Banshee|bean-sídhe]] (banshee).
With her sisters, [[Macha (Irish mythology)|Macha]] and the Morrigan or [[Anu (Irish goddess)| Anand]], Badb is part of a [[Triple deity|trio]] of war goddesses known as ''[[The Morrígan|the three Morrígna]]''.<ref name="Invasions">{{cite book | author=Macalister, R.A.S.
