What is proofreading?
According to the Cambridge Dictionary, proofreading is the act in which “one finds and corrects mistakes in text before it is printed or put online”. If we look for it in the Oxford Dictionary we will see that to proofread is “read (printer’s proofs or other written material) and mark any errors”. Meaning that proofreading is the process in which a text is brought to a publishing standard. It is generally a fancy word for correction and often it will be interchangeably used with QA (quality/assurance).
