Descriptivfe Writing is a type of writing where you describe something using many very descriptive adjectives.
This is an example of Descriptive Writing -->
"The golden-maned horse thundered through the lush green meadow and then it stopped. It bent its neck to the green grass and sniffed the sweet smell of the colourful flowers."
cool is a cool word
arcane is an arcane word
dull is a dull word
monosyllabilic is not a monosyllabilic word
So cool, arcane and dull are all self-descriptive words
Insead of saying, "I'm gonna take a dump" Joe was over descriptive and said, "I'm gonna sit on a block of porcelin and let a huge, brown chunk slide out of my ass and into a lake of previously-white water, turning it into a swamp of organic toxic waste."
