IPA: /ˈmɜːrmeɪd/
KK: /ˈmɜrˌmeɪd/
A mythical creature that has the upper body of a woman and the lower body of a fish, often found in stories and folklore.
In the story, the mermaid saved the sailor from drowning.
Mermaid → The word is formed from "mere" (from Old English *mearc*, meaning sea or lake) and "maid" (from Old English *mægden*, meaning young woman or girl). A mermaid is thus a young woman of the sea.
Think of a 'young woman' ('maid') who lives in the 'sea' ('mere') — that’s why a mermaid is a mythical creature that is part woman and part fish.
