A novelette (or, rarely, novelet) is a piece of short prose fiction. The distinction between a novelette and other literary forms is usually based upon word count, with a novelette being longer than a short story, but shorter than a novella. The Science Fiction and Fantasy Writers of America Nebula awards for science fiction define the novelette as having a word count of between 7,500 and 17,500, inclusive.
The Chambers Dictionary claims that the terms novelette and novelettish have also been used in a derogatory manner, suggesting fiction which is "trite, feeble or sentimental."
