3rd Grade Spelling Words
140+ essential spelling words for third graders (ages 8–9) — Dolch sight words, prefixes, homophones, multi-syllable words, and introductory Latin roots.
What Spelling Skills Do 3rd Graders Learn?
Third grade is where spelling becomes strategic. Children move beyond sounding out and memorizing individual words — they start learning systems. Understanding prefixes, Latin roots, and homophone rules lets a 3rd grader tackle unfamiliar words with confidence. By year's end, a typical student should be able to:
Dolch 3rd Grade Sight Words (41 Words)
The Dolch 3rd grade list is the final level of the core sight word sequence. Most of these words are phonetically predictable — the challenge is automaticity. Children at this level should read and spell them instantly, without sounding out, so mental resources stay free for comprehension.
See the full Dolch third grade sight word list for these 41 words grouped in tens, how to teach them, and free listen-and-type practice.
Practice Tip: At 3rd grade, sight words that aren't automatic yet are best drilled in short daily bursts rather than long sessions — 2 minutes of flashcards every morning beats a 20-minute session once a week. SpellCrush's daily streak feature is perfect for this.
Common Prefixes (24 Words)
Prefixes are one of the highest-leverage spelling tools. The four most common prefixes — un-, re-, pre-, dis- — account for roughly 58% of all prefixed words in English. A child who understands these four can make educated guesses about thousands of unfamiliar words.
Practice Tip: Give children a base word and challenge them to add every prefix they know. Does "reunkind" make sense? Why not? Discussing which prefixes work with which bases builds intuition faster than drilling lists alone.
Essential Homophones
Homophones — words that sound identical but have different spellings and meanings — are one of the most persistent sources of spelling errors, even in adults. The key to mastering them is always context plus a memory trick.
- • there = a place, or the word that starts a sentence like there is
- • their = belonging to them
- • they're = the short way of writing they are
- • to = toward something, or the word in front of a verb as in to run
- • too = also, or more than you want
- • two = the number 2
- • your = belonging to you
- • you're = the short way of writing you are
- • its = belonging to it
- • it's = the short way of writing it is or it has
Four more your 3rd grader will meet
- hear / here — hear = to listen; here = this place (You hear with your ear, and ear is hiding inside hear.)
- know / no — know = to have knowledge; no = the opposite of yes (Know keeps a silent k from Old English cnawan, the same silent k as knee and knife.)
- write / right — write = to put words on paper; right = correct, or not left (Write starts with the same silent w as wrist and wrong.)
- where / wear — where = in what place; wear = to have clothes on (Where has here inside it, and both are about place.)
Multi-Syllable Words (12 Words)
Three-syllable words are the first real challenge for independent spellers. The strategy that works best: break the word into syllables, spell each part separately, then join them. Clapping syllables before writing locks in the structure.
Practice Tip: "Beautiful" and "probably" are perennial 3rd grade stumpers. For beautiful: "big elephants are usually tall if fully unloaded later" — an acrostic for B-E-A-U-T-I-F-U-L. Silly mnemonics stick far better than repetition alone.
Introductory Latin Roots
English borrows heavily from Latin, and learning even a handful of roots unlocks dozens of related words. Third grade is an ideal time to introduce the concept — children are old enough to appreciate the "code-breaking" aspect and young enough that it becomes instinctive.
Practice Tip: Turn it into a word hunt. Give your child the root "port" (carry) and challenge them to find as many "port" words as they can in a dictionary or around the house. This active discovery builds retention far better than passive list memorization.

Free Online Spelling TestFrequently Asked Questions
What spelling words should a 3rd grader know?
By the end of 3rd grade, children should have mastered all 220 Dolch sight words, be able to spell common homophones correctly in context, use prefixes and suffixes accurately, and spell most two-syllable words reliably. Strong 3rd graders can spell 400–500 words.
What new spelling patterns do 3rd graders learn?
3rd grade introduces prefixes (un-, re-, pre-, dis-, mis-), common homophones (their/there/they're, to/too/two), multi-syllable words, introductory Latin roots (port, rupt, struct), silent letters (kn-, wr-, -mb, -gh), and irregular plurals.
How do I help my 3rd grader with homophones?
Context is the key to homophones. Teach each word with a sentence that makes the meaning clear. Mnemonics help too: "here" hides inside "there" — both are about place. SpellCrush's AI hints generate age-appropriate memory tricks for tricky words.
My 3rd grader still struggles with their/there/they're. Is that normal?
Completely normal — these are among the most commonly confused words even for adults. The trick is always to ask: "Can I replace this with they are?" If yes, use they're. If it's a place, use there. If it belongs to them, use their. Daily practice in context (not just lists) is the fastest path to automaticity.
