Basically it is:
- Copying someone else's words without using quotation marks and citing the source.
- Restating or summarizing someone else's original or specialized ideas without citing the source.
- Pretending someone else's work is your own.
Avoid Plagiarism by developing good habits in terms of citing information
For instance, whenever you copy/paste from a document ALWAYS enclose it in quotation marks AND make a note of the source
