It is always good practice to revise and if necessary completely rewrite text in documents to ensure that they are accurate, concise, and the best they can be.

Roman (that is upright type) is the standard text typeface, but for various reasons italic type (that is slanted to the right) is adopted. This is often to indicate some form of departure from normal text for the reader to interpret the word or words in a certain way.
