What does RX mean

Please enlighten a foreigner.

I get all this spam offering International Legal RX and the like. There is also this thread with several pharmacological references to RX. What is RX?

It just means a prescription.

But what does it stand for? Why RX, not P?

Take thou.

In Latin.

Tris

An abbreviation for the Latin word “Recipe”, meaning “Take”, as in “Take 3 pills per day.”

Use of X in Medical Abbreviations (or Ux of X in Mx Ax)

Makes me want to say “Hey doc, can you write me a “take thou” for <some medication>?” :smiley:

Uncertain, according to our ubiquitous friends at Wikipedia.

The latin term recipe - “take!” is the usual explanation for “Rx”. The “x” is a summation of the last five letters of that latin command (the fact that old pharmacy signs often place the “x” a little lower than the “R” supports the idea).

Wikipedia tells me that it either comes from the Eye of Horus or the symbol of Jupiter, either of which were used in medical-related contexts.

ETA: Too slow on the uptake. :confused:

And that’s why “recipe” means “list of ingredients and procedure for making something to eat” - it’s all the things you “take” and what you do with them.

Interesting.

Oddly enough, I have seen the word “receipt” used to mean “recipe” in the culinary sense, which does make sense since a “receipt” can mean a “taking” of something. However, I’ve only seen it used this way in one place, a translation of Jules Verne’s The Mysterious Island. I don’t know if that was a translator’s error, or if was really used that way in 19th century English.

I’ve heard that in the 20th century, in some parts of America. 'Course, those parts were noted for speaking a 17th-century English dialect. :wink:

The only place I remember seeing it used that way was in a short story in a grade school reader, set in the 40s or 50s in a small Kansas or Iowa town.

Interestingly, that’s the earliest cited meaning in the OED. But the modern meaning shows up just a little later, which suggests both meanings may have been in use at the same time. From the OED:

Louisa May Alcott, Little Women, chapter 28.
