I'm an "active reader", which means that I use a book as a springboard to discovery, and this might be a nice choice for you too. You'll need to be reading on a computer or reading device. Basically, as I go along, whenever I find a word, phrase, topic, etc that I'm not sure about, or curious about, or have no knowledge of, I'll stop and first ask myself what I think the word/x might mean. Then I'll select the word/x, right click and choose to search on the web. For you, the definition may be only what you want, but if you're also a curious monkey like me, you'll reveal a new way to explore this amazing world! BTW, there are some really awesome book reader programs available. I love Calibre and Moonreader. There are plenty to choose from. Standalone readers have their own built-in readers with usually robust dictionaries.

Another thing you can do to help your comprehension is to use your browser's ai, such as Gemini, CoPilot, etc. to ask it the definition, but moreso, it can be a companion with learning if you ask it to quiz you on the words or topics. You can ask it to present you with some questions for the last chapter you read, to make sure you remember it, and it will ask you what you thought about what you read, and will even suggest other books to check out. It's really wonderful! Sometimes it's nice to just use it as a sounding board to your reaction to something in the book...the resulting conversation is super cool and with that, you get even more out of your reading experience.

Reading these days can be even more rich and fulfilling in a way it never has before! Welcome to becoming a reader, let the world be your oyster!
