fax

Once upon a time, before email took over, the fax machine was a normal part of office life. The word "fax" is short for facsimile, which means an exact copy. A fax machine scans a document and sends its image over a telephone line to another machine, which prints out a matching copy.

While it is less common now because of email and scanning apps, faxing is still used in legal, medical, and government settings, especially where older systems, formal rules, or paper records still matter. You can use the word as a noun ("I received a fax") or a verb ("Please fax those papers to me"). Today, the term can also include online fax services, where you send a digital file from a computer or phone without using a traditional machine.

The word "fax" comes from facsimile, a term for an exact copy. In everyday use, it usually means a document sent through a fax machine or the act of sending one. A traditional fax machine scans a page, turns the image into signals, sends those signals over a telephone line, and lets another machine print a copy at the other end.

In its busiest years, especially in the 1980s and 1990s, the fax machine was a basic office tool. To send one, you would feed a paper into the machine, dial the other machine's number, and wait while the page was transmitted. The receiving machine would then print a copy that looked the same as the original.

Although email, scanned attachments, and digital signing tools have replaced it in many places, faxing has not disappeared. It is still common in some healthcare, legal, business, and government settings, often because of habit, existing workflows, or rules that still accept or expect faxed documents.

Today, the word can also refer to online or virtual faxing, where a file is sent through the internet to a fax number, and the service connects with fax equipment if needed. The idea is still the same: sending a copy of a page from one place to another. Even though the technology feels old-fashioned now, the word "fax" still carries the story of a time when sending a page across a long distance in a minute felt surprisingly modern.
