What are the best dictionaries for kids? if you’re looking for a dictionary, here are the best kids’ dictionaries for children in the classroom, library, or at home. (Scroll down for a scavenger hunt and dictionary activity ideas.)

These dictionaries for kids are kid-friendly nonfiction reference books that contain illustrations and definitions to help young learners learn to spell and learn new vocabulary words.

As an educator, I understand the ease of an online dictionary (like the Merriam-Webster Dictionary app or Dictionary.com), but I think that at an early age, it’s important to look up words in a physical dictionary.

One big reason is that in a physical dictionary book, children can practice alphabetizing. They need to be able to look up words in the order of the alphabet. To best use the dictionaries, teach your kids how to alphabetize not just the first letters of the words but the second, third, and fourth letters. Then, when they have alphabetizing skills, teach them how to use the headwords at the top of the pages.

That being said, I like that the online dictionaries for kids and dictionary apps also include audio pronunciations, etymology, and related words, including antonyms and synonyms. In addition, these apps have word lists for learning new words like this one from Merriam-Webster.

Best Dictionaries for Kids

My First Dictionary
ages 5+
Each of the 1,000 words in this dictionary is accompanied by a photo or illustration with the part of speech (nouns, verbs, and adjectives). The words listed are most commonly encountered by young children and include kid-friendly definitions. This kids’ picture dictionary is best for preschoolers and early elementary ages.

Scholastic Children’s Dictionary
ages 6+
I highly recommend this easy-to-read beginner-level dictionary with the words in red plus the parts of speech definition, a kid-friendly proper pronunciation guide, sample sentences, kid-appropriate definitions, and some illustrations. This dictionary for kids includes a thesaurus plus guides to grammar, idioms, geography, and US presidents.

Merriam-Webster Children’s Dictionary by DK
ages 7+
Merriam-Webster Children’s Dictionaries are my favorite reference tool. This traditional dictionary contains 35,000 words and 3,000 full-color illustrations, making it my top pick for classrooms and libraries. I also like that the borders are color-coded for each letter of the alphabet. The words include the definition, notes on spelling and punctuation, and examples.

ages 6+
This is an illustrated dictionary with Spanish and English common words for kids who are learning English or learning Spanish. Grow your vocabulary with over 1000 words in two languages and a picture for each word.

Mrs. Wordsmith’s Storyteller’s Illustrated Dictionary
This deluxe illustrated storytelling dictionary gets kids jazzed about words with over 1,000 words illustrated in entertaining cartoons. It’s a great word-finding resource to help grow a child’s vocabulary and directly improve their writing skills and storytelling ideas.

Scholastic Pocket Dictionary of Synonyms, Antonyms, & Homonyms
ages 8+
Designed for upper elementary and middle school students with more than 12,000 synonyms and 10,000 antonyms at their fingertips, this thesaurus book is a great reference tool. It requires some understanding of how to use it — with the antonyms in italic font after the list of synonyms.

Every Word Tells a Story by Tom Read Wilson, illustrated by Ian Morris
ages 7+
Would your kids love this playful, colorful, illustrated etymology dictionary? I’m not a kid but I love it! For each letter, dive deeper into four unique words that begin with that letter. One of the words includes a featured poem, and all the words include their etymology and definitions. The book is decidedly British with words like bobby and hoover, which is a fun experience for American kids.

Pocket Dictionary by Merriam-Webster
ages 10+
This is the best advanced children’s dictionary with words, pronunciations, and corresponding definitions is best for high school students to carry in their backpacks — but not people my age (over 50) who need reading glasses because the print is too tiny! Merriam-Webster is a classic dictionary, and if you want a bigger size, try this one. I’d recommend this pocket dictionary for kids in middle school and high school.

The Dictionary of Difficult Words by Jane Solomon, illustrated by Louise Lockhart
Want a mesmerizing wordplay book that is even better than a word-a-day calendar? This oversized dictionary contains an incredible selection of 400 words starting with abecedarian (someone who is learning the alphabet) and continuing to Zeppelin. Learn 15 new words for each letter.

Every word includes the pronunciation, part of speech, and definition. You’ll find words like haberdashery, ichthyologist, luddite and mugwump, mulligrubs, mumpsimus, and mishpocha. Read one of these words (or more) every day. Then try to use it at least a few times in a sentence. It won’t be too onerous, and you won’t be ramfeezled; learning new words might just be a salubrious experience because you’ll soon become a sesquipedalian.
