Grammarly outlines key steps for summarizing articles: read closely, pinpoint main ideas, and rewrite in your own words without plagiarism.
Effective summaries stay under 250 words, focus on thesis and big-picture supports, and cite the source properly.
Avoid details or opinions—stick to objective overviews that capture the article's core goal, like informing or persuading.
