mermaid Cultural  

  1. A legendary marine creature with the head and torso of a woman and the tail of a fish; the masculine, less well-known equivalent is a merman. Though linked to the classical Sirens, mermaids may be nothing more than sailors' fanciful reports of the playful antics of dugongs or manatees.

Etymology

Origin of mermaid

First recorded in 1300–50, mermaid is from the Middle English word mermayde. See mere 2, maid

Explanation

A mermaid is mythical sea creature that has the head and upper body of a woman and a tail of a fish. Mermaids appear in folklore from around the world, from the ancient Greek sirens who were said to lure sailors to a watery death, to the Mami Wata water spirits from African mythology. The Disney version of mermaids comes from the Hans Christian Andersen story "The Little Mermaid," about a mermaid who trades her life in the sea for love with a human. Mermaid means "maid of the sea," from mere, "sea" in Middle English.
