Editing is the act of reading written work and pointing out any errors. Spelling, language, accentuation, and consistency are the most common types of errors.
The term “proofreading” is derived from a distributing term that depicts an early printed duplicate. Traditionally, typesetters would mastermind letter tiles onto massive plates, which were then used to print pages of a book. However, before they started producing a large number of duplicates, a ‘proof’ form was sent off to the distributor for final approval.
