This is an important step in the simplification of the question before us, which is to discover an intelligible line of demarcation between them and the Tuatha Dé Danann. In order to come nearer to that, the names here in point have to be now more closely examined. Let us begin with the most intelligible of them, namely, that of the Fomori. It is derived partly from the Irish word muir, 'sea,' and Irish historians persistently treat it as meaning sea-rovers or pirates, as if they understood the whole compound to mean transmarini, whereas it can only mean submarini, as the prefix fo does not mean 'beyond, over or on,' but 'under or below.'
