How it is used
- Suspiciously identical - improperly the same as another - 两篇论文雷同 (liǎng piān lùnwén léitóng) the two papers are identical (implying plagiarism).
- Negative connotation: implies unoriginal copying or coincidence that shouldn't be; common in academic/legal notices (如有雷同，纯属巧合).
- Not for legitimate sameness (that's 相同); 雷同 flags illegitimate or troubling duplication.
