Hello is ubiquitous and has become a common greeting in many countries in the world. Even in Germany, it’s become an excepted greeting when meeting another person. However, the more traditional greetings are still expected when meeting someone for the first time or when entering a small place of business or a restaurant. It was not, however, used as greeting during the Regency. I researched all of Jane Austen’s books, did a search on Google Advanced Book Search and found no reference to it at all. Then looked it up in the Oxford English Dictionary OED).
According to the OED, hello as a term to get someone’s attention or register surprise has been used since around the 1820’s in North America. There are no British references.
Hello as a greeting was first recorded in the US in the US Yankee Clipper in 1853.
It does not appear to have been in common use in Britain until around the 1920’s. The first recorded usage was by P. G. Wodehouse’s Money for Nothing iv. 76 ‘Hello, sweetie-pie,’ said Miss Molloy in 1928. Wodehouse, as some of you might know, was a widely read contemporary English writer. We generally believe that spoken usage preceded written usage by about ten years. That still does not take us back to the Regency.
So what did they say? They would have used the greetings we all used before “hello” wiggled it’s way into almost universal parlance. Good morning, good afternoon, good day, good evening. When meeting by chance, “well met” is fine.
Let me know what other greetings you think of.
