Clearly there are a lot of us who find the English language to be interesting and worth thinking about. On this topic, I would like to recommend a challenging new book: Linguistics: Why it Matters by the linguist Geoffrey K. Pullum.
A few sentences from the introduction:
"This book is about the point of studying human language scientifically, and what importance that study has for broader concerns. The relevant scientific study is known as linguistics...
"Linguistics is not at all the same as the study of particular languages or their literatures. ...
"I'm not trying to give any sort of introduction to linguistics in this relatively short book; plenty of other books do that. What I'm trying to do is to survey just a few topics that I feel make a clear case for saying that linguistics is not just an intellectually intriguing academic subject but a practically important one." (pp. vi-vii)Each chapter of the book covers a topic that's studied by linguists, and explains its importance. I enjoyed each one, but I find the last chapter, "Machines that Understand Us," especially intriguing. In it, the author explodes some common misconceptions about seemingly very capable machines like robots, search engines, and iPhones. Often people become convinced that these devices understand language and use it in a human way; newspaper articles often hype such understanding in an exaggerated way.
It's so easy to be fooled by a computer! Many programs such as Google search, Alexa, or Siri seem to respond in a human way to a wide variety of questions, either typed or spoken. However, the book explains the critical difference between producing a convincing response, based on a machine's vast databases and a few tricks, and actually "understanding what the question said." (p. 88)
The chapter on machine understanding also includes a thought-provoking (and I would say rather difficult) discussion of what would be involved in effective processing of natural languages -- a task that hasn't yet been accomplished.
This is subtle -- I hope you decide to read it for yourself!
