Answer:
An informal writing/essay that is spoken in slang, figuration of speech, a broken syntax or non appropriate text. It can also mean simple writing or direct emotion to the reader.
Examples of informal writing:
"LOL, Lit" (Any kind of slang)
"I, I'm "(Any kind of first person material)
There are some articles you can find online with informal writing, you'll find those same examples.
P.S
Have an Amazing Day and Good Luck!
