DYFALU: A Welsh term for a form of fanciful conceit in which a string of sequential metaphors compares an object to a number of diverse things--often using compound words in a manner similar to the Anglo-Saxon or Old Norse kenning.
A comedy, in contrast to a tragedy, is a genre of drama in literature that is characterized by its happy and vivacious ending. Besides making the audience happy, a comedy rather importantly intends to evoke humour and amusement in the audience by means of extensive laughter.
In the wake of Aristotle's Poetics (335 BCE), tragedy has been used to make genre distinctions, whether at the scale of poetry in general (where the tragic divides against epic and lyric) or at the scale of the drama (where tragedy is opposed to comedy).
