6th Grade Spelling Words

150+ essential spelling words for sixth graders (ages 11–12) β€” advanced Greek and Latin roots, etymology, the -able/-ible distinction, -ance/-ence words, and middle school spelling bee vocabulary.

What Spelling Skills Do 6th Graders Learn?

Sixth grade is the transition into middle school β€” and spelling transitions with it. Word lists become longer, academic vocabulary spans more subjects, and spelling bee preparation gets serious. Students who understand etymology (where words come from) gain a decisive advantage: they can explain even the most "illogical" spellings. By year's end a typical student should:

πŸ”€Use advanced Greek and Latin roots (chron, cred, psych, spec)
βœ…Choose correctly between -able and -ible
πŸ“–Spell common -ance and -ence words from memory
πŸ›Understand how etymology explains silent letters and unusual spellings
πŸŽ“Spell middle school academic and literary vocabulary
πŸ†Handle 6th grade spelling bee words with root-based strategies

Advanced Greek and Latin Roots (36 Words)

These roots push beyond the basics into the patterns that define middle school and high school vocabulary. Mastering them at 6th grade sets students up for SAT and ACT vocabulary sections years later.

chron-
"time"
Greek
chronological
synchronize
chronicle
chronic
anachronism
chronology
mor / mort-
"death"
Latin
mortal
immortal
mortify
mortgage
morbid
posthumous
cred-
"believe"
Latin
credible
incredible
credit
credentials
credulity
discredit
spec / spect-
"look, see"
Latin
spectacle
inspect
respect
suspect
perspective
spectacular
psych-
"mind, soul"
Greek
psychology
psyche
psychiatry
psychic
psychological
psychologist
aqu-
"water"
Latin
aquatic
aquarium
aqueduct
aquifer
aquamarine
subaqueous

Practice Tip: "Psychology" trips up 6th graders because of the silent P. Once they know the Greek root psych (soul, mind), the spelling becomes a badge of knowledge rather than a random rule: "I know this word came from Greek, so I keep the Greek spelling."

The -able vs -ible Distinction (16 Words)

Both suffixes mean "capable of" or "worthy of," but they come from different sources. The practical rule: if the base is a complete English word, use -able. If the base is a Latin root that doesn't stand alone in English, use -ible.

-able

Used after complete English base words

comfortable
← comfort
predictable
← predict
dependable
← depend
honorable
← honor
remarkable
← remark
imaginable
← imagine (-e)
manageable
← manage (keep -e)
changeable
← change (keep -e)
-ible

Used after Latin roots that aren't stand-alone English words

visible
← vis (see)
terrible
← terr (frighten)
responsible
← respons (respond)
incredible
← cred (believe)
flexible
← flex (bend)
possible
← poss (able)
accessible
← access
compatible
← compat

Practice Tip: Quick test β€” remove the suffix. Does a real word remain? "comfort" β†’ yes β†’ comfortable. "vis" β†’ not an English word β†’ visible. This test works about 85% of the time, which is good enough for most contexts.

The -ance vs -ence Problem (16 Words)

Unlike -able/-ible, there's no reliable rule for -ance vs -ence β€” they both make the same /ens/ sound. The practical solution is to memorize the most common words in each group and build pattern recognition over time.

-ance words
assistanceappearanceperformanceguidancesignificanceresistancetoleranceignorance
-ence words
evidenceintelligenceconfidencedifferenceexistenceinfluencesentenceexperience

Practice Tip: When a student genuinely can't remember, -ence is slightly more common in academic writing. Using -ence as the default guess is better than -ance β€” but the 16 words above appear frequently enough to be worth memorizing individually.

Etymology: Why Words Are Spelled That Way

Etymology β€” the study of word origins β€” is the single most powerful tool for understanding "illogical" English spellings. Silent letters aren't random: they're fossils of how words were once pronounced, or markers of which language a word was borrowed from. Once students understand this, spelling starts to feel like history.

psychologyGreek

psyche (soul/mind) + logos (study). The silent P comes from Greek β€” English kept the spelling even though the sound was dropped.

debtLatin

From Latin debitum. The silent B was reinserted by scholars in the Renaissance to honor the Latin origin β€” it was never pronounced in French or early English.

islandOld English

Old English igland. The S was added by confusion with the French word isle β€” they're unrelated roots. The S has never been pronounced.

WednesdayOld English

WōdnesdΓ¦g β€” Woden's day (the Norse god). The D in the middle was once pronounced. Spelling preserved the old form; pronunciation shortened it.

colonelFrench / Italian

From Italian colonello β†’ French coronel (pronounced ker-nel) β†’ English kept French spelling but Italian pronunciation. The most irregular English word by sound-to-spelling ratio.

knightOld English

Old English cniht. The kn- was fully pronounced in Old English (k-nicht). Silent letters are fossils of how words were once spoken.

Practice Tip: "Colonel" is a great conversation-starter for why English spelling is the way it is. The pronunciation (ker-nel) came from an Italian dialect version; the spelling came from French. English picked up both from different sources and never reconciled them. That backstory makes the word unforgettable.

Weekly Practice Schedule for 6th Graders

By 6th grade, students can take more ownership of their practice. Build in self-assessment and strategy development:

Monday
Introduce 12 new words. Research the etymology of 3 of them β€” where do they come from? What does the root mean?
Tuesday
SpellCrush practice β€” 15–20 min. Focus on -able/-ible words. Self-score and note which base-word rule applied.
Wednesday
-ance/-ence drill. Write each word, check spelling, flag any that were guesses. These need extra repetition.
Thursday
Spelling bee simulation. Practice asking for definitions, language of origin, and use in a sentence.
Friday
Test + reflection. For each missed word: what is its root? What does that root mean? Does knowing that help?

Frequently Asked Questions

What spelling words should a 6th grader know?

By the end of 6th grade, students should comfortably spell multi-syllable academic and literary vocabulary, use Greek and Latin root knowledge to decode new words independently, correctly spell words with French and Old English origins, and handle advanced suffix patterns (-ance/-ence, -able/-ible).

What is the difference between -able and -ible?

-able is used with complete base words (comfortable, predictable, dependable). -ible is used with Latin roots that are not complete English words (visible, terrible, responsible). Quick test: remove the suffix. If a real English word remains, use -able. If not, try -ible.

What are good spelling bee words for 6th graders?

Strong 6th grade spelling bee words include: conscientious, supersede, Mediterranean, lieutenant, Caribbean, bureaucracy, silhouette, and surveillance. These test Latin, Greek, and French borrowings alongside less common English patterns.

How does etymology help with spelling?

Knowing where a word comes from explains many irregular spellings. The silent P in psychology comes from Greek (psyche = soul). The silent B in debt comes from Latin (debitum). Etymology turns confusing spellings into logical puzzles β€” and students who understand the history remember the spelling far better.
