The word "删减" is formed by combining the character "删", which means to delete or remove, often from written text, and the character "减", which means to reduce or subtract. "删" historically relates to cutting with a knife, reflecting its use in editing, while "减" incorporates the radical for ice (冫) to imply reduction. Together, they create a compound word meaning to cut down or reduce, specifically in the sense of editing or abridging content.
