Add Append Onto Your Vocabulary

Append is a somewhat formal word. Lawyers, for example, often speak of appending items to other documents, and lawmakers frequently append small bills to big ones, hoping that everyone will be paying attention only to the main part of the big bill and won't notice. When we append a small separate section to the end of a report or a book, we call it an appendix. But in the early years of e-mail, the words we decided on were attach and attachment, probably because appendixes are thought of as unimportant, whereas the attachment is often the whole reason for sending an e-mail.
