Question Do you know the origin of the expression "mind your Ps and Qs?"
Many thanks.
Answer Hi Peter
The phrase dates to the late 18th century--at least 1779. The exact origin is unknown, but several competing hypotheses seem to be the most likely.
The first is that it derives from the phrase p and q which was an abbreviation for prime quality. This English dialectical term dates to the 17th century. So to mind your p's and q's would mean to be exacting in detail and ensure high quality.
The second is that it refers to difficulty children had in learning to distinguish between the letters p and q, being mirror images of one another. To learn one's p's and q's is a phrase meaning to learn one's letters is first recorded around 1830--somewhat later but not impossible as the origin. Often this explanation is identified with printers and distinguish between a p and a q in type, but the early use exclusively deals with children, not printing.
The third, first suggested by Farmer and Henley at the turn of the 20th century, is that the phrase comes from the practice of maintaining a tally in pubs and taverns. Marks under column p, for pint, or q, for quart, would be made on a blackboard. To mind them would be to watch to ensure that the bartender did not misattribute someone else's drinks to your tab or to mark a pint as a quart.
The last is from the world of printing. Typesetters had to be skilled in reading letters backward, as the blocks of type would have mirror images of the letters. The lower-case letters p and q were particularly difficult to distinguish because they are mirrors of one another. Typesetters had to be particularly careful not to confuse the two.
Which is the correct one is anybody's guess.
