In --- as is said --- an excess of caution, I decided to look up the derivation of “posh.” Several dictionaries assured me I was quite wrong, that the term did not derive from “Port Out, Starboard Home,” a “common misconception.” I sit here humbled. How many other erroneous ideas do I have? Am I, like so many others, often wrong but never in doubt? Are you? How would we know? What can we be sure of?
Of course, the dictionaries could be wrong. Perhaps we shouldn’t let them ruin a good story. No, we must trust our best sources. We seek the truth, as best we can, knowing how fallible we can be.
