  • noun Great merriment.

from The Century Dictionary.

  • noun Demonstrative mirth or merriment; gleeful exhilaration; social gaiety; jollity.
  • noun Synonyms Hilarity, Joy, Glee, Joviality; gaiety, exhilaration. Joy is not often used of the excitement or overflow of animal spirits, but is rather and almost distinctively an affection of the mind. Glee is a strong word for an acute or ecstatic pleasure that expresses itself in mirthfulness and other demonstrative signs of high spirits. Joviality is that feeling or character which, being itself gay, merry, or jolly, brings others into the same mood; the word is generally used in a good sense. Hilarity is more often, but not necessarily, used of mirth, laughter, or other signs of exhilaration exceeding the limits of reason or propriety. See animation, mirth, gladness, happiness.
