Unfortunately, writers, authors, editors and broadcasters often have communication failures. Sometimes they hear words, but the words they think they heard are not the words that the speaker spoke.
In reality, high school kids were not wearing lumps of volcanic rock which are normally used as an abrasive to remove calluses from feet. They were wearing Pumas, a brand of sneakers -- which the reporter was unaware of. (There's a double problem here. When "pumice" is pronounced properly, its first syllable rhymes with "hum" -- not with "room." A reporter should know this.)
Sometimes a print or broadcast journalist will hear a word and think she or he understands what it means, but doesn't.
In 1965, a power blackout shut down the supply of electricity to New York, New Jersey, New England and Ontario, Canada. Over 30 million people were powerless for up to 12 hours.
The sincere but ignorant person apparently assumed that a power grid was a simple gizmo that could be purchased at a nearby Radio Shack -- not the network that connects power companies in multiple states.
The misunderstanding probably would not happen today, when independent people proudly "live off the grid."
New Haven, Connecticut (home of Yale University) seems to be a hotbed of mis-speaking, resulting from mis-hearing and mis-reading.
Someone attending the second year of high school in most places is a “sophomore,” from the Greek words for “wise” (sophos) and “foolish” (moros). In New Haven, I heard it pronounced “southmore.”
When a department store advertised a set of bedroom furniture pieces in a newspaper, it was described as a “bedroom suite.” In New Haven, people who were enticed by the ad and went to the store would ask to see a “bedroom suit.” Some of them were probably shown pajamas.
Some local stores — either out of ignorance or in an effort to correct the pronunciation of their ignorant customers — advertised “bedroom sweets,” thereby setting the English language back to the pre-Chaucer era.
As a teenager I sold clothing and shoes in my father’s store, and my ears were offended several times a day.
Not everyone in New Haven was educated at Yale.
And don't get me started on malapropisms. My wife has a cousin who says "old timer's disease" for "Alsheimer's" disease.
And don't get me started on editors who replace an author's correct words with wrong words. I once challenged a co-author's vocabulary -- but I was wrong.
