5. The book was very ........... . interesting interest interested

The book was very interesting! You know, this word often pops up when referring to something that piques your curiosity or holds your attention. It’s a great word to sprinkle into conversations when you want to express how captivating a story or topic is. Don’t confuse "interesting" with "interested," though! While "interesting" describes the quality of something that grabs attention, "interested" refers to a feeling you have towards something. So, you would say, "I am interested in this book," but you would admire the book itself as "interesting."
