A stack of books on a table

Having a wide vocabulary is an essential skill to develop throughout one’s life, and it’s especially vital for grade students that have exams and college in their future. That’s why we’ve developed this collection of books to increase vocabulary, including one book aligned to each grade between 4th and 11th grade so that any student can stay on track. We’ve picked these novels because each has excellent diction, and they’re slightly challenging yet within the capabilities of each grade.

If you’re a student wondering “How can I improve my vocabulary?”, you’ve made it to the right place! This article isn’t just a list of books, however—we’ve included three vocabulary quizzes (one for each set of grades) with original questions from Piqosity’s team of educators, so you can quiz your current vocabulary knowledge! 

One tip before we dive in: don’t be afraid to read ahead! Reading books at a level 1-2 grades ahead is a great way to learn new vocabulary if you’re an adept reader, especially if you plan to take an admissions exam like the ISEE or if you’re expecting to take the ACT/SAT in the next few years.

Winnie grows close with the family and wants to drink from the spring once she’s grown up, but a manipulative businessman puts everyone at risk. This is one of the most riveting children’s books, an adventure packed with imagery and vocabulary that will grow your reading capabilities.

“And then Miles caught a fish. There it flopped, in the bottom of the boat, its jaw working, its gills fanning rapidly. Winnie drew up her knees and stared at it. It was beautiful, and horrible too, with gleaming, rainbow-colored scales, and an eye like a marble beginning to dim even as she watched it. The hook was caught in its upper lip, and suddenly Winnie wanted to weep.” (Babbitt, Chapter 17) 

5th Grade: The Invention of Hugo Cabret, Brian Selznick

The Invention of Hugo Cabret, Brian Selznick A children’s historical fiction novel, The Invention of Hugo Cabret takes place in 1930s France, following a young boy named Hugo who lives in a Paris train station and secretly maintains its clocks; at the same time, he’s attempting to repair an automaton that belonged to his father, a once-famous filmmaker.

“The old man in the toy booth was arguing with the girl. She was about Hugo’s age, and he often saw her go into the booth with a book under her arm and disappear behind the counter. The old man looked agitated today. Had he figured out some of his toys were missing? Well, there was nothing to be done about that now.” (Selznick, Chapter 1)

6th Grade: Jane Eyre, Charlotte Brontë

A coming-of-age story from another era that you’ll still be able to relate to, Jane Eyre is one of the best classic novels for middle grade readers. Jane is an orphaned girl that’s been outcasted her whole life, treated poorly by the people around her since she was young. Follow her as she grows up and falls in love—will she be isolated again, or has she found her family? With a strong female protagonist that has inspired young readers for generations, Jane Eyre is drenched with precise diction and themes that will resonate with you.

“Our clothing was insufficient to protect us from the severe cold: we had no boots, the snow got into our shoes and melted there: our ungloved hands became numbed and covered with chilblains, as were our feet: I remember well the distracting irritation I endured from this cause every evening, when my feet inflamed; and the torture of thrusting the swelled, raw, and stiff toes into my shoes in the morning.“ (Brontë, Chapter 7)

7th Grade: They Both Die at the End, Adam Silvera

They Both Die at the End, Adam Silvera If you’re wondering what to read that will captivate you, expand your vocabulary, and make you a little existential—this is the book for you.

Mateo and Rufus have both been notified that they’ll die by the end of the day, so they meet up to make the most of the last day of their lives. This novel chronicles their last day on Earth, a moving story that will remind you of the beauty in life. 

“The roar of the approaching train drowns Mateo out a little at the end there, but it’s fine, I get what he’s saying. The real victory here is catching a train instantly. Now we can safely rule out falling onto the exposed tracks, getting stuck while rats run by us, and straight chopped up and flattened by the train—Mateo’s grimness is already rubbing off on me.” (Silvera, page 73).

8th Grade: The Hobbit, J. R. R. Tolkein

The Hobbit, J. R. R.

Follow Bilbo Baggins as he journeys with the wizard Gandalf and a group of dwarves to recover their treasure from the dangerous dragon, Smaug. 

“Bilbo knew it. He had read of a good many things he had never seen or done. He was very much alarmed, as well as disgusted; he wished himself a hundred miles away, and yet-and yet somehow he could not go straight back to Thorin and Company emptyhanded. So he stood and hesitated in the shadows.” (Tolkein, page 22).

“The rugged summits of the rocky hills were dimly visible on the edge of the horizon, through the misty fogs; every now and then some heavy flakes of snow showed conspicuous in the morning light, while certain lofty and pointed rocks were first lost in the grey low clouds, their summits clearly visible above, like jagged reefs rising from a troublous sea.” (Verne, Chapter 9)

“People spoke of Momma as a good-looking woman and some, who remembered her youth, said she used to be right pretty. I saw only her power and strength. She was taller than any woman in my personal world, and her hands were so large they could span my head from ear to ear. Her voice was soft only because she chose to keep it so.” (Angelou, Chapter 7)

11th Grade: 1984, George Orwell

1984, George OrwellThis final read can’t not be in this list of books to increase vocabulary. In a dystopian society where the government constantly surveils and controls everyone, how can you have free will and individuality? Protagonist Winston works in this government, and he’s responsible for rewriting history to match the current political agenda; however, he secretly hates the government and plots to overthrow it. A classic science fiction novel that will broaden your perspective and diction, 1984 explores the dangers of totalitarianism and stresses the importance of our freedoms of thought and expression.

“More even than of strength, he gave an impression of confidence and of an understanding tinged by irony. However much in earnest he might be, he had nothing of the single-mindedness that belongs to a fanatic. When he spoke of murder, suicide, venereal disease, amputated limbs, and altered faces, it was with a faint air of persiflage.” (Orwell, Chapter 16)
