Talk:Rx

Meaning origin
Where did the meaning Rx come from?

It is from an old symbol (like a capital R with a stroke through its diagonal line - I don't know how to type it) that is the first letter of Latin recipe - receive. SemperBlotto 12:48, 23 August 2008 (UTC)

Use for "prescribed" (adj.)
On page iii of the California Air Resources Board's December 2020 Public Comment Draft, is used in the phrase, which may suggest that  is being used in place of the term. Supporting this idea is the fact that is a phrase used in other parts of the document and is a common term/collocation. The term/collocation can also be found in use, but is significantly less common. &mdash;The Editor's Apprentice (talk) 19:31, 8 June 2022 (UTC)
