How many words can you have in common without being plagiarism?

There is no strict Word limit that defines plagiarism, as it depends on context and usage. Generally, common phrases or terms that are widely used and not unique can be shared without issue. However, if a substantial portion of text (often considered to be more than a sentence or two) is copied without proper attribution, it can be deemed plagiarism. Always aim for originality and proper citation to avoid any potential issues.
