Rx (prescription)

I found several different theories about the origin of this symbol "Rx" used by doctors before a prescription. Is it an abbreviation? Is it some ancient chemical symbol?

Several origins sound less credible. One source said that Rx is a corruption of the symbol for Jupiter and that a prayer to Jupiter would speed healing. That doesn't make sense to me since Jupiter (also known as Jove) was the god of the sky and thunder and king of the gods in Ancient Roman religion and mythology and not associated with healing.

I couldn't find a symbol for the god, but the symbol for the planet looks like an odd 4 and is said to represent an eagle, which is Jupiter's bird.

Another theory is that the Rx symbol evolved from the Eye of Horus, an ancient Egyptian symbol associated with healing powers. This has a bit more believability because pharmacy has been around for thousands of years and the first recorded prescriptions were etched on a clay tablet in Mesopotamia around 2100 B.C. There were the equivalent of drugstores in Baghdad in the eighth century A.D.

The problem is that the Eye of Horus (also known as wadjet, wedjat or udjat) though it is an ancient Egyptian symbol of protection, royal power, and good health, doesn't look like the Rx.

The most likely origin is that this symbol seen on doctor’s prescription pads and signs in pharmacies is derived from the Latin word “recipe,” meaning “take.”  The word recipe has had the same function from the 13th through the 17th centuries. The two letters were a 19th-century way of easily reproducing a 16th-century symbol - the letter R with a line through its slanted leg.
℞  that meant the "R" is functioning as an abbreviation - not an X.
It wasn't till around 1911 that "Rx" came to be used as meaning the the noun "prescription." A recipe associated with cooking came into being in the early 17th century, which is when America’s earliest drugstores came into being in big cities. The first college of pharmacy in the United States was founded in 1821 in Philadelphia.

Today in America, the centuries old mortar and pestle - tools of the trade - is often used by pharmacists as an industry symbol along with Rx.

An Okay Story

OKay

I came across a book, OK: The Improbable Story of America's Greatest Word, that got me thinking about this common word that doesn't get much thought. Is okay (AKA OK or O.K.) America's greatest word?  Yes, according to author Allan Metcalf, English professor and executive secretary of the American Dialect Society.

OK is such a common colloquial English way of denoting approval, assent, or acknowledgment, that I also posted this on my One Page Schoolhouse website.

"Okay" has spread as a loanword to other languages.

It has shades of meanings and is used as several parts of speech: As an adjective, "It's okay to sit here" means "acceptable" but "Their food is just okay" means "mediocre" rather than being "good."

People use it as an adverb ("She sings okay.")

"Okay, I'll leave now" makes it an interjection meaning compliance and "Okay, I like that option" indicates "agreement."

You can use it was a verb, as in "The office okayed my travel expenses."

These two letters (I'm not a fan of the "O.K." version because I don't see it as an abbreviation.) are very versatile.

The OK or ring gesture is a common hand sign. It even has an online Unicode symbol (U+1F44C) and is a commonly used emoticon online 👌 . Connecting the thumb and index finger into a circle, and holding the other fingers straight or relaxed away from the palm indicates something is okay.

Divers use the sign to say that you are okay or to ask another person if they are okay.

Take note that in other contexts or cultures, this same gesture has different meanings or connotations that are not simply linguistic, including ones that are negative, offensive, financial, numerical, devotional. For example, in France the "OK" gesture bears both positive and negative connotations, and in parts of the Arab world, this sign represents the evil eye and is used as a curse.

The origin is not definitive. One version is that at a Chicago bakery named O. Kendall and Sons they stamped Army biscuits with the company initials OK, or maybe it was a Boston baker named Otto Kimmel who did that on his vanilla cookies. But why attach the meanings to it beyond it being a kind of logo?

I also found that it might be d from the Choctaw word "okeh" -which means "it is true." That sounds more sensical, though I found no path for its entry into English.

There is an origin that attaches "OK" to the Boston Morning Post back in 1839 where as an editor's joke it was used as an abbreviation for a misspelled version of the phrase "all correct." Huh? That makes no sense to me.

I prefer a New Jersey diary entry of William Richardson in 1815. He is writing about a journey from from Boston to New Orleans and writes: "Arrived at Princeton (NJ), a handsome little village, 15 miles from N Brunswick, ok at Trenton, where we dined at 1 P.M."  We assume he meant that he is giving his Trenton meal an "all right" review. But it is unlikely that Richardson invented the ok term as a personal short form, so where did he get it from and why did it spread?

We also sometimes use "A-OK" to mean a stronger form of okay. The term seem to have originated with the space program.

There is also "okie-dokie," a slang term that also means okay that was popularized in the Our Gang (The Little Rascals) films.

OK had usefulness as a short form in 19th century telegraph messages with their abbreviations that resemble our own Tweets. And if OK isn't enough of a shortening of okay, you will also see the single "K" in text messages.
