What would most likely be found in informal writing

Hiya,

Slang, figure of speech, & abbreviations would probably be found in most informal writings. If you want to write a formal email to your boss, would you list words such as "ain't, nah, wym, ttyl, totes?" No, of course not because that would be considered informal.

Hope this helps!
