History & Etymology
Researching the Etymology of the word beach was interesting. The OED entry says it hasn’t been fully updated in over 100 years, and I’m not a big fan of relying on a wiki for information. I’ve tried to bring all of the explanations I’ve come across into an interesting story, but that’s about all it is so take it with a grain of salt and enjoy. The history of the word probably went something like this.
The old english word “bache” referred to the land a stream or creek ran through. Because a lot of streams and creeks are lined with stones, over time the word came to refer to those rocks made smooth by the running water. In some places the word beach still refers to stones smoothed by water.
Eventually the a changed to an ea,the e was dropped from the end, and it became the word we know today. Beach.
When someone would say, “I’m going for a walk on the beach” they actually meant, “I’m going for a walk on the smooth stones.”
After years of usage like the example I just gave the meaning was transformed into the definition we have today.
