understanding plagiarism and referencing

Me and many people think of plagiarism as copying another's work, or borrowing someone else's original ideas. But terms like "copying" and "borrowing" can disguise the seriousness of the offense.

But after i read and Search on the web i learnt many things.
1- to steal and pass off (the ideas or words of another) as one's own
2- to use (another's production) without crediting the source
3- to present as new and original an idea or product derived from an existing source.
In other words, plagiarism is an act of fraud. It involves both stealing someone else's work and lying about it afterward.

Strategies for Avoiding Plagiarism
1. Put in quotations everything that comes directly from the text especially when taking notes.
2. Paraphrase, but be sure you are not just rearranging or replacing a few words.
3. Check your paraphrase against the original text to be sure you have not accidentally used the same phrases or words, and that the information is accurate.
