An anecdote (noun) is a specific member of a species within the anecdotal phylum. We will not define anecdotal here because we defined it in the previous entry in The Words Project and we believe it would be reprehensible of us to facilitate and encourage laziness. Click the damned link and look it up yourself.
Examples of anecdotes include a Sasquatch (or the Sasquatch if you think such a thing exists but there is only one) and the Loch Ness Monster. (People only talk about the Loch Ness Monster, which begs the question, how the hell long can that thing live? If there’s only one, even if it ever did exist, surely it must be dead by now. There can’t be anymore if it didn’t have another Loch Ness Monster to mate with. And, if there’s only ever been one, how the hell did it come into existence in the first place? Evolution doesn’t work like that.)
Anecdotes are the stuff of legend; probably only the stuff of legends.
