mind your p's & q's

Does anyone think its possible the expresion "mind your P’s & q’s could have come from the following?
The Welsh language was developed from the language spoken by the ancient Britions and is decended from the original Aryan stock which is the basis for most European languages. It belongs to the Celtic group of original Aryan which was itself divided into the Q-speaking Celts and the P-speaking Celts. Scotish Gaelic and Manx belong the first (the Q) group: Welsh, Cornish and Breton belong to the P group.

Doubtful.
More likely, it’s because little kids tend to mix up lower case q’s with lower case p’s.

I’ve heard it was confusing the p and q letters when sorting typeface, made more difficult because they are mirrors of one another and you see the mirror of a letter when you look at the type metal. But don’t know if this is legit.

Welcome to the SDMB, katie.

A link to the column you’re commenting on is appreciated. Providing one can be as simple as pasting the URL into your post, being sure to leave a blank space on either side of it. Like so: What’s the origin of the expression “mind your P’s and Q’s”? - The Straight Dope

I take it you’re talking about the column What’s the origin of the expression “mind your P’s and Q’s”?.

Naw, that’s overly complex. The explanation should be rather straight forward and simple. Otherwise, people wouldn’t have understood it when other people used it and started using it themselves. You have to explain why this British people divided themselves into two groups, explain why the two groups are “p” and “q”, and why most people who weren’t Welch were able to understand the saying enough that they not only understood its meaning, but decided they liked it and used it themselves.

Besides, there is a whole boatload of things wrong with your explanation:
[ul]
[li] Welch is not related to most other European languages. Most other European languages stem from Latin or Germanic roots. Welch is a Celtic language and isn’t even in the same sub-group as other Celtic languages. [/li]
[li] Aryans refer to a whole boatload of ancient people in the Northern Indian sub-continent. Now, I haven’t looked at a map recently, so I might be wrong about this: Wales isn’t all that close to Northern India.[/li]
[li] The reference to a single people of Aryan stock is a racist idea from the late 19th century and picked up by the Nazis who somehow though that those Northern Indians somehow had blond hair and blue eyes and now lived in Germany and in the Scandinavian countries. And, those German-Aryans certainly didn’t have a very high opinion of the British “races” and certainly didn’t think anyone on that island could possibly be of Aryan stock. I hope you’re not suggesting you have an affinity to this non-scientific and completely discredited theory.[/li][/ul]

I read somewhere that it comes from pubs, meaning pints and quarts.

I’m pretty sure it doesn’t come from the fact that there are P-Celtic and Q-Celtic languages. The first reference in print to the expression “mind your p’s and q’s” is from 1779. I believe that the terms “P-Celtic” and “Q-Celtic” didn’t appear until sometime in the nineteenth century.

Incidentally, it’s not typical to refer to Proto-Indo-European as “Aryan” anymore. “Aryan” can refer to the Indo-Iranian branch of the Indo-European languages but not to Proto-Indo-European itself. It’s better not to use the term “Aryan” anymore, since it has unfortunate associations.

In 1989, cecil was right up there with the thinking of many etymologists. But times change. Database serching of newspaper, Google Book Search and more. All bring forth new discoveries every year, sometime every month.

The draft revision for the 2009 OED says:

.

Further, with regards to the etymology, OED says,

It gets more and more complicated all the time.

Sounds like it’s time for Cecil or the SAB to update that one.

Reported this thread; she started the same thing in Comments on Cecil’s Columns, and it should be merged there.

Hopefully that’s what I just did. So, if the continuity in the thread seems strange, I merged the two threads, deleting her/his duplicate post. Carry on.

Indeed; what strikes me about the OED’s examples is that they all use a prepositional form: [at/in/upon/on] [his/her/your] [pee/p./p’s] and [kue/q./q’s]. That is different from the modern usage, in which we are merely admonished to mind them, rather than told to be at or in or on them.

So it seems that the P and Q originally referred to some sort of state or location, possibly figurative, rather than objects or ideas.

I’m really sorry. I only submitted part one. Here’s the rest. Truly interesting.

To be fair to her, she posted the question in GQ, but it was moved. It’s likely that she didn’t see the column and wasn’t commenting on it.

edit - my mistake, she posted it twice.

The P/Q split applies to more than Celtic. The Italic languages (Latin is the only one known to non-specialists, but Latin was originally only one of a family) have it, and it can be observed in IE as a whole, where Latin Q can correspond to Greek P.

True, but in any case, it’s a nineteenth century term (since it’s a distinction that wasn’t made until after the idea of Indo-European languages was created), so it couldn’t have been the origin of the term “mind your p’s and q’s.”

It seems odd to me that here it’s written out as “Pee” and “Kue”. Is that normal for that time?

Nothing was normal for that time. Typography was still only just beginning to standardize spelling and punctuation in English at the time.

Welsh is indeed related to most other European languages. Celtic is one branch of the Indo-European language family. Most European languages are Indo-European, coming from several different branches: Celtic, Italic, Greek, Germanic, Albanian, Slavic, and Baltic (that may not be complete, and other Indo-European families are spoken outside of Europe). The only major non-Indo-European languages in Europe are, I believe, Hungarian, Finnish, Estonian, and Basque. In pre-Roman times, Celtic languages were spoken over much of Western Europe.

Aryan is an obsolete term for (proto)-Indo-European. The India connection has to do with the Indo- part.
