A novella is a work of prose fiction somewhere in length between a short story and a "full length" novel. One writer's association defines it as being between 17,500 and 39,999 words in length. The word was originally an Italian one meaning a tale or piece of news and as such was applied to the work of such writers as Boccaccio. The word novel comes from the same source, although the full length novel evolved many years later.
