While I was reading this thread, I found some of the answers interesting.
I’d like change the question a bit, and confirm or deny a phenomenon I discovered years ago.
Having a conversation with a black cook at a restaurant where I was a bartender, we came to talk about language, speech, and so forth. One thing I found most interesting. He told me that growing up, he -and any person - was forbidden to tell someone that X was a liar. It was blasphemy of the highest order, and time for a whipping.
Now he could say, “Momma, David is fibbing.”, and that’s OK. He could say that Ann didn’t tell the truth about who broke the vase. In short, it was acceptable to convey the information that X was not being truthful with any word other than “lie” or "liar. Use them, and you got the cane immediately whether or not what you said was the truth.
We both come from the south, and I’ve never heard of such a thing. He told me it’s as common and widespread as Coca Cola. After polling the entire staff, it turns out only the black employees knew of this rule.
Over the years with different groups or at different employers, I have occasionally brought it up as an experiment, and the results were always the same. Black people were raised to understand that saying the word **lie **was vile, unacceptable, and would result in a whipping. No white people I ever asked had ever heard of such a rule of grammar.
Clearly this is a “black thing”.
Now, I realize I’m painting with broad brush, but since all of my “data” predates the internet, I now have the chance to reach beyond the Southeast and eliminate any geographical or confirmation bias and ask dopers across the country. Up until now, I’ve only spoken to Georgians about this.
Forget whether you were told that directly calling someone a liar was rude. That might be a given. My question - mostly for black members here - is thus: were you forbidden (or taught) as a child that using the words lie or liar was particularly wrong, above and beyond just “regular” bad behavior? Did it warrant punishment?
And let’s narrow it down if possible by including your (approx) age, race, and state where you lived during your childhood, or formative years. Also, who, if anyone told you this, e.g. parent, grandparent, etc…
I hope no one is offended by this question. It’s just an interesting phenomenon I came across one day, and I’m interested in the reason or origin. My guess would be the source is religious in nature, but that’s just a guess.
