mirth

noun / murth / mithless / mirthful

an emotion that follows humor and accompanied by laughter and amusement

We, in the ages lying
In the buried past of the earth,
Built Nineveh with our sighing,
And Babel itself with our mirth;
And o’erthrew them with prophesying
To the old of the new world’s worth;
For each age is a dream that is dying,
Or one that is coming to birth.

Arthur O’Shaughnessy (The Music-Makers)
