pn f. name of an ancient Irish war- goddess . Acc. to Stokes RC xii 128 , De Jubainville RC xxix 195 , the first component is cognate with O.H.G. mara and A.S. maere, cf. Eng. nightmare, Fr. cauchemar, the second being identical with rígan `queen'; attempts have also been made to equate the Morrígan with the fairy Morgan of the Arthurian saga (< mor `sea', `water'), see RC xxxiv 259. In the Mid.Ir. period the first syll. seems to have been commonly equated with mór `great' and the vowel is often accented.
