Which meaning of append matches adding something to a written work such as a letter or a book?

• A. To remove something
• B. To detach
• C. To attach something; to affix
• D. To add something to a written work such as a letter or a book

Answer: (D)

Append means to add something to the end of a document. In writing, you often see material placed at the end, like an appendix or an extra note, which is exactly what happens when you append something to a letter or a book. So the meaning that states adding something to a written work captures the typical use of the word. The other options describe removing or detaching, which are the opposite actions, or describe attaching in a more general way without the specific sense of adding to a written work.
