I just found this, and everyone else might already know about it, but! It’s essentially a collections of descriptions (in the form of quotes, lists of words and ‘thematic micro-stories’) that each center around a given theme.
So if you search for “crying” you’ll see user descriptions from literature and often their own writing as well.
Of course there is an abundance of purple and poorly constructed prose. But there are also little gems like this, from Atwood’s Lady Oracle:
I never learned to cry with style, silently, the pearl-shaped tears rolling down my cheeks from wide luminous eyes, as on the covers of True Love comics, leaving no smears or streaks. I wished I had; then I could have done it in front of people, instead of in bathrooms, in darkened movie theatres, shrubberies and empty bedrooms, among the party coats on the bed.
And you can also contribute your own stuff if you’re so inclined.
Anyway, add it to your bookmarks right next to the Dictionary of Similes and before you know it, you’ll have 3467346 ways to describe a ‘dark and stormy night.’
