where did the phrase mind your p's and q's come from
Mind your Ps and Qs According to Michael Quinion, "[i]nvestigations by the Oxford English Dictionary in 2007 when revising the entry turned up early examples of the use of Ps and Qs to mean learning the alphabet. The first is in a poem by Charles Churchill, published in 1763: “On all occasions next the chair / He stands for service of the Mayor, / And to instruct him how to use / His A’s and B’s, and P’s and Q’s.” The conclusion must be that this is the true origin."[2]
