‘删改’ is a compound verb meaning ‘to edit and revise’, specifically by removing (删) unwanted parts and modifying (改) existing content. The first character 删 means ‘to delete’ or ‘to cut out’, often implying removal of text, images, or data; the second character 改 means ‘to change’, ‘to alter’, or ‘to correct’. Together, they describe an integrated editing process that involves both deletion and revision—not just one or the other. This term is commonly used in writing, publishing, software development, and academic work.

It emphasizes intentional, thoughtful revision rather than casual tweaking. Unlike simpler verbs like 修改 (to revise) or 删除 (to delete), 删改 highlights the dual action and is often used when substantial restructuring is involved—such as refining a draft manuscript, polishing a report, or cleaning up code comments. It carries a neutral-to-formal register and appears frequently in professional, educational, and digital contexts.
