what does the phrase "mind your p's and q's" originate from?

Question

extra credit question for my trig class

Answer 1

Various possibilities:

- Mind your pints and quarts. This is suggested as deriving from the practise of chalking up a tally of drinks in English pubs (on the slate). Publicans had to make sure to mark up the quart drinks as distinct from the pint drinks. This explanation is widely repeated but there's little to support it, apart from the fact that pint and quart begin with p and q.

- Advice to printer’s apprentices to avoid confusing the backward-facing metal type lowercase Ps and Qs. I've never heard any suggestion that printer should mind their ds and bs though, even though that has the benefit of rhyming, which would have made it a more attractive slogan.

- Mind your pea (jacket) and queue (wig). Pea jackets were short, rough woollen overcoats, commonly worn by sailors in the 18th century. Perruques were full wigs worn by fashionable gentlemen. It is difficult to imagine the need for an expression to warn people to avoid confusing them.

- Mind your pieds (feet) and queues (wigs). This is suggested to have been an instruction given by French dancing masters to their charges. This has the benefit of placing the perruque in the right context - so long as we accept the phrase as being originally French. There's no reason to suppose it is from France and no version of the phrase exists in French.

- It is advice to children learning to write to take care not to mix up the lower-case letters p and q. Again, the 'd' and 'b' counter argument applies.

- It derived as reminder to children to be polite. This is supposed to be as a form of 'mind your pleases and thank-yous' - 'mind you pleases and kyous'. Pretty far-fetched that one.

- P and q stands for "prime quality." There is, or rather was as this now seems to have also been withdrawn, a 1612 citation which links PQ with 'prime quality'. If that's the origin why isn't the phrase mind your PQ?

Answer 2

What replaced into defined at college: P's = Priorities Q's = features continuously keep in mind which you have "priorities" in life, and the "features" of your character will allow you to gain them... genuine answer is: Shortening for "Pints and Quarts", that have been the two important measurements for beverages. while now we use pints, a million/2 pints, photos etc, there was once Pints and Quarts whilst issues have been given rowdy, as they have an inclination to do in pubs, you will in many cases hear something like "innovations your Pints and Quarts" and a warning or some such. this replaced into shortened to "innovations your P's and Q's

Answer 3

Well, it did have to do with drinking, but from afterwords:
The men in the taverns had to line up (queue) to take a pee (p).

Answer 4
