Plagiarism Check
01 Definition
Plagiarism Check meaning: A review that compares text against existing sources to find copied or unattributed passages.
A plagiarism check runs a piece of writing through software that scans large indexes of web pages and documents for matching phrases. It flags passages that resemble published work so writers can rewrite them or add proper citation. A match is not always plagiarism, since common phrases and quoted sources trigger flags too.

Why it matters
How Plagiarism Check fits the work
Running a check before publishing helps protect a brand's credibility and reduces the risk of copyright complaints or embarrassment from unattributed copying.
In context
The editor ran the draft through a plagiarism check, which flagged two sentences at 90 percent match to a competitor's blog and prompted a rewrite.
Practical note
Similarity scores are estimates, not verdicts. Tools miss paraphrased ideas and over-flag quotes and boilerplate, so a human should read every flagged passage in context before acting.
