"Plagiarism occurs when a writer duplicates another writer's language or ideas and then calls the work his or her own. Copyright laws protect writers' words as their legal property. To avoid the charge of plagiarism, writers take care to credit those from whom they borrow and quote." (definition provided by The New Dictionary of Cultural Literacy via CredoReference, 10/29/2014.)
