MER-may is incorrectly written, and should be written as "MERMAID" being its meaning: Loan vocabulary, anglicism. Means, in fact, be hybrid between women and animals, both marine bird. Although the general trend ( and vulgar ) It is thought that the SIRENS are beings upper half in anthropomorphic form of woman and the Cantle bottom, true sirens of the " Odyssey " of Homer, Ovando with their sorcerers songs Ulysses, tied to the mast of his ship, were, in fact, birds; what otherwise may have the expression " song of sirens "? Perhaps " " sing? the fish, or are the birds singing? Therefore means Mermaid, and this is to be half woman, half Songbird.
