Short Story, Novelette, Novella or Novel (?)

Was reading a few related articles in Wikipedia and seeing the specific word count as demarcations between the various stories was more amusing to me than I was previously confused at wondering what the definitions actually were.

I have previously read how the various stories are differentiated by things such as subplots, alternate perspectives and such, but to so specifically divide by word count seems amusing.

Utimately it makes little difference to me, I self publish, and doubt I'll ever get any kind of awards, for anything I do (fiction or otherwise).

I write stories and will leave it to others, with the time to waste on such things, to decide how to define them. Hopefully, at least not being called crap.
