4th Grade Spelling Words: 100+ Words Grouped by Spelling Pattern

A free list of 4th grade spelling words for ages 9 to 10, organized by the prefixes, suffixes and word patterns fourth graders learn.

Quick answer: 4th grade spelling words focus on word parts: prefixes like mis- and in-, suffixes like -tion, -ous and -ful, homophones (piece/peace), silent letters (answer, often), irregular plurals (wolves, geese) and longer words such as temperature and vegetable. Most classes practice 12 to 15 words a week.

What Do 4th Graders Learn in Spelling?

Fourth grade is when spelling meets vocabulary. Children learn that words are built from parts, and that knowing a prefix or suffix helps with both spelling and meaning. They also work with more multi-syllable words, irregular plurals and words that sound alike but mean different things.

Breaking long words into syllables and word parts is the key skill this year.

Every school uses its own program, so treat this list as practice, not an official curriculum. For other ages, see our spelling bee words by grade.

4th Grade Spelling Words by Pattern

The 100 words below are grouped by spelling pattern, because children remember a rule far better than a random list.

Prefixes: mis-, pre-, non-, over-, in-, im-

A prefix changes the meaning without changing the base word.

misspell, mistake, preview, nonstop, overdue, impolite, incorrect, invisible, disappear, unknown, overflow, preschool

Suffixes: -tion and -sion

Both make a "shun" sound at the end. -sion often follows words ending in d or s.

action, motion, nation, station, mention, vision, division, decision, attention, direction, collection, invention

Suffixes: -ous, -ful, -less

These suffixes turn nouns into describing words.

famous, nervous, joyful, colorful, fearless, endless, dangerous, curious, helpful, spotless

Homophones

Words that sound the same but have different spellings and meanings.

piece/peace, aloud/allowed, threw/through, flour/flower, knight/night, weak/week, cereal/serial, principal/principle

Multi-syllable words

Clap the syllables, then spell one chunk at a time.

calendar, celebrate, temperature, vegetable, interesting, wonderful, umbrella, yesterday, important, remember, together, vacation, discover, alphabet

Silent letters and tricky sounds

These letters are written but not heard.

answer, often, guess, guard, whistle, ghost, wrinkle, scissors, knuckle, wrist, doubt, design

Irregular plurals

Some plurals change f to v, add -es, or change the whole word.

heroes, potatoes, wolves, halves, geese, women, cities, monkeys, shelves, tomatoes, oxen, countries

Challenge words

Common words that adults still misspell.

business, separate, library, address, minute, height, weight, breathe, although, especially, actually, February

Key Spelling Rules for 4th Grade

1. A prefix never changes the base word

Just add it on: mis + spell = misspell (two s's), in + visible = invisible. This explains many double letters.

2. Change f to v in many plurals

For words ending in f or fe, the plural often uses -ves: wolf → wolves, half → halves, knife → knives.

3. Add -es to words ending in consonant + o

Many such words take -es: hero → heroes, potato → potatoes. Some, like piano, just take s.

4. Keep the y after a vowel

If a vowel comes before the y, just add s: monkey → monkeys. If a consonant comes before it, change y to i: city → cities.

Example Sentences for Tricky 4th Grade Words

Using a word in a sentence shows its meaning, which matters most for words that sound alike or break the usual rules.

Fun Ways to Practice 4th Grade Spelling Words

  • ➥Word part puzzles: write prefixes, base words and suffixes on separate cards and build as many real words as possible.
  • ➥Homophone pictures: draw a quick picture for each word in a homophone pair, like a flower and a bag of flour.
  • ➥Syllable clap and write: clap a long word, write one syllable per clap, then join them.
  • ➥Spelling detective: find list words in a book or newspaper and highlight them.
  • ➥Word puzzle games: the daily Spelling Bee puzzle asks players to build words from seven letters. Fourth graders can aim for the Good or Solid rank and look for prefixes and suffixes in the hive.

How to Build a Weekly 4th Grade Spelling Test

Fourth grade tests can mix spelling with meaning. Include a homophone sentence and one word where students add a prefix or suffix.

PartItemsPurpose
Pattern words10This week’s prefix, suffix or pattern
Review words2Words often missed in earlier weeks
Word building1Add a prefix or suffix to a base word
Homophone sentence1Choose the right word in a sentence

Read each word, use it in a sentence and read it again, just as a pronouncer does in a spelling bee. Our spelling practice routine shows how to spread study across the week.

Using Word Parts to Spell Long Words

When a fourth grader meets a long word, the best strategy is to break it into parts. Take uncomfortable: it is un + comfort + able. Each part is easy to spell, and together they make a long word. The same works for disagreement (dis + agree + ment) and carelessly (care + less + ly).

Make a habit of asking three questions about every long word: Is there a prefix? What is the base word? Is there a suffix? This turns spelling into problem solving, which most fourth graders enjoy.

Spelling in 4th Grade Writing

In fourth grade, students write longer stories, reports and opinion pieces, so spelling matters beyond the weekly test. A good habit is to circle any word you are unsure about while writing, then check those words at the end instead of stopping every few seconds. This keeps ideas flowing and still produces correct work.

Teachers often notice that students spell a word correctly on Friday's test but misspell it in a story the next week. To close that gap, ask students to use each week's words in a short paragraph. Writing the words in context helps them move from short-term memory into everyday writing.

Finally, encourage a personal "word bank" at the back of a notebook. Every time a word is misspelled twice, it goes in the bank and gets practiced again until it sticks.

Tips for Parents

Ask your child to explain why a word is spelled the way it is. Saying "mis plus spell, so two s's" shows they understand the rule. Keep a small notebook of tricky words and review it for a few minutes each evening.

Using This List for a Class Spelling Bee

For a fourth grade bee, use prefix and suffix words in the early rounds and homophones (with a sentence) and challenge words for the final. Our guide on how to host a classroom spelling bee covers rules, roles and tie-breaks.

Final Thoughts

Fourth grade spelling is about understanding how words are built. When children know prefixes, suffixes and plural rules, long words stop looking scary. Practice a little each day and talk about why words are spelled the way they are.

Frequently Asked Questions (FAQs)

Most fourth grade classes practice 12 to 15 words a week, often with a few challenge words.

Fourth graders usually study prefixes, suffixes like -tion, -sion and -ous, homophones, silent letters and irregular plurals.

Words like separate, business, temperature, scissors and breathe are often hard for fourth graders.

Both sound like "shun." -tion is more common, while -sion often follows base words ending in d, de or s, as in divide → division.

Teach word parts, use words in sentences, practice homophones with pictures and review a short list of tricky words each day.
