Versus versus "vs." in writing?

Question

In writing, when should one use the abbreviation "vs." as opposed to the full "versus"? This abbreviation seems to have special status from common usage. What is the origin of that, and in what writing contexts is it important?

Answer 1

Like any abbreviation, vs. should be used in a casual writing setting (emails, notes, rough drafts, etc.). If writing a formal business document or academic essay, I would always lean toward writing out the full word unless you've received specific permission to abbreviate.
