# From the MLA Style Manual, 1985:
"Plagiarism is the use of another person's ideas or expressions in your writing without acknowledging the source . . .. The most blatant form of plagiarism is reproducing someone else's sentences, more or less verbatim, and presenting them as your own. Other forms include repeating another's particularly apt phrase without appropriate acknowledgement, paraphrasing someone else's argument as your own, introducing another's line of thinking as your own development of an idea, and failing to cite the source for a borrowed thesis or approach."
