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.
A satire, on the other hand, is intended to do more than just entertain; it tries to improve humanity and its institutions. A satire is a literary work that tries to arouse the reader's disapproval of an object â a vice, an abuse, a faulty belief â by holding it up to ridicule.
