Geasa. Pronounced Gassa. It is the plural of geis (often written geas), and signifies oath-bound injunctions or undertakings. In the old days for a man to be under geasa meant that he was solemnly bound to do such and such a thing, or, as it might be, to refrain; and the bond once taken could not be broken without loss of honour.
Ildanna. The old Irish word is best represented by Il-danach, that is, the Master of Craft, or Master of the Many Arts, and is a name which is specifically given to Lugh Lamfada, Lugh the Long-Handed.
Illann. This frequent name of Illann, or Illan, is identical with Ullin, so familiar in Scotland through the famous poem of “Lord Ullin’s Daughter.”
Lir. Pronounced sometimes Lirr, but generally Lear.
Lochlann. A general name for the whole of Scandinavia, including, of course, Denmark, and not, as sometimes stated, of Norway only.
Lugh. This name is pronounced Lu, or Loo, and I have so given it in the text.
Manannan. Pronounced Mon-on-awn. He is the Neptune of Gaelic mythology, but holds a more mysterious and more potent position in the Gaelic Pantheon than his classical congener.
Maev. The name of this most famous queen of antiquity is variously spelt. The original is Meadb, or Medbh, and is properly pronounced Mave (rhyming with wave).
Murhemne. The original of this is Magh Muirteimne, pronounced Moy-mwir-hev-na. It is the plain from the Boyne to near Carlingford.
Moyle. This is the commonest pronunciation of the old Gaelic Maol, though the word is best known in Scotland as Mull (from the Mull of Cantyre). It is applied to the sea between Cantyre and Ulster.
