Daoine maithe is Gaelic for "the good people", which is a popular term used to refer to the fairies in Irish folklore. They are generally human like though there are exceptions such as the Puca or Mermaid. The defining features of the Irish fairies are their supernatural abilities and their temperament. If treated with respect and kindness, Irish fairies can be quite benevolent; however, if they are mistreated they will react cruelly.
