200 Difficult Grade 7 Spelling Words

Why Grade 7 Spelling Words Are So Hard to Spell

Seventh grade pushes a speller deep into real competition territory. The word bank leans hard into vocabulary borrowed wholesale from other languages, Latin and Greek roots dense enough to build genuine academic terms, and long multi-syllable words that simply take more working memory to hold in your head letter by letter. We pulled 200 words straight from the SpellingKids Grade 7 word bank — the same words used in our flashcards and spelling practice — and sorted them into seven categories, so you can see exactly which pattern is giving your speller trouble and focus practice time where it actually counts.

1. Words Borrowed From Around the World (25 words)

A real spelling bee word list pulls from every language English has ever borrowed from — "bolero" and "boutonniere" arrive from French by way of fashion and dance, "chaparral" comes from Spanish, and "chivalry" traces back to Old French "cheval," a horse. These words rarely follow standard English spelling logic because they were never built from English sounds to begin with, so recognizing "this word feels borrowed" is the real skill, not trying to sound it out the usual way.

• Accoutre
• Admonish
• Agreeable
• Altruism
• Amenable
• Appease
• Apprentice
• Balcony
• Banality
• Beaumontage
• Blameless
• Bolero
• Boutonniere
• Brochure
• Bureau
• Caliber
• Cavalry
• Chaparral
• Chattel
• Chivalry
• Colonel
• Compound
• Cotton
• County
• Crescent

2. Latin & Greek Word Roots (25 words)

This is where the academic vocabulary building gets serious — "accelerate" comes straight from Latin "celer," meaning swift, and "circulatory" builds on "circulare," to go round, the same root behind "circle" and "circus." The same logic unlocks "autochthon" (from the earth itself) and "axiomatic" (a self-evident truth). Most competition-level words at this age are Latin or Greek at their core, which makes root recognition the single highest-leverage skill on this whole list.

• Accelerate
• Adenosine
• Affiliate
• Allegorize
• Anastrophe
• Annunciator
• Anthracite
• Antitussive
• Arable
• Arctic
• Assistant
• Attempt
• Autochthon
• Axiomatic
• Benignant
• Bipartite
• Brankursine
• Campaign
• Capitulum
• Carminative
• Castor
• Center
• Chromium
• Circulatory
• Classify

3. Double Consonants (25 words)

A doubled letter never changes how a word sounds out loud, which is exactly why it is so easy to drop by ear — nothing about pronouncing "holluschick" or "hypallage" tips off a speller that a consonant repeats. These words have to be learned by sight and by spelling them out loud, syllable by syllable, rather than by listening alone.

• Chessboard
• Communion
• Compellable
• Cranberry
• Dabbler
• Deerstalker
• Dissent
• Drizzle
• Effluence
• Encompass
• Epollicate
• Faultless
• Fellmonger
• Fillip
• Glitter
• Gutter
• Harrow
• Holluschick
• Hypallage
• Illogical
• Imminent
• Irregular
• Jellylike
• Kaddish
• Knotty

4. Tricky Vowel Combinations & Diphthongs (25 words)

Vowel teams like "ea," "ou," "oi," and "eu" can each spell several different sounds depending on the word, which is why "corporeal" and "mesoseismal" spell their vowel sounds in ways that do not match how they look at first glance. These words are best learned in small clusters by shared pattern, not studied alphabetically.

• Acreage
• Confound
• Corporeal
• Deafen
• Endosteal
• Experience
• Growthful
• Handleable
• Horsepower
• Inaugural
• Journal
• Kerchief
• League
• Mesoseismal
• Moiety
• Naught
• Outlandish
• Panacea
• Papeterie
• Paucity
• Polissoir
• Propound
• Pseudonym
• Purlieu
• Reverie

5. Common Prefixes & Suffixes (25 words)

Prefixes like "de-," "dis-," and "im-" and suffixes like "-ity," "-ible," and "-ance" change what a base word means or what job it does in a sentence — recognizing the pattern turns a long, intimidating word like "disguisable" or "incredulity" into a short root plus a few predictable pieces bolted onto the front or back.

• Canonicity
• Consecutive
• Decisive
• Deltohedron
• Dentifrice
• Desuetude
• Devolve
• Disburse
• Discord
• Disguisable
• Dispersion
• District
• Diversion
• Elusion
• Equitable
• Etiology
• Flexuosity
• Fragmentize
• Galenical
• Guidance
• Impedance
• Impolitic
• Incogitable
• Incredulity
• Indite

6. Science & Nature Vocabulary (25 words)

A meaningful share of every real spelling bee word list comes from science and the natural world — chemistry terms like "manganese" and "monoxide," physics and geology terms like "geodesy" and "oligocene," everyday nature words like "rainstorm." These words reward students who read outside the classroom, since a speller who already knows what "electrolyte" means or what a "pachyderm" is has a real head start on spelling it correctly.

• Colander
• Conditioner
• Dormant
• Electrolyte
• Foliate
• Geodesy
• Hyacinth
• Icicle
• Inoculate
• Lignite
• Lucent
• Manganese
• Manufactory
• Matter
• Microphone
• Monoxide
• Noctovision
• Oligocene
• Pachyderm
• Photosphere
• Precipitant
• Predominate
• Rainstorm
• Scandium
• Shelter

7. Longer Multi-Syllable Words Worth Knowing (50 words)

The final category covers the longer, multi-syllable words that show up once a speller has outgrown the easier lists — words like "kinesthetic" and "pococurante" that combine several of the patterns above into a single, longer challenge. These are the words most likely to separate strong spellers from great ones at an actual competition.

• Chairborne
• Clockmaker
• Conchiform
• Constituent
• Contravene
• Corybantic
• Diplomatic
• Doctrinaire
• Extramural
• Gravimetry
• Hemispheric
• Ineptitude
• Inseparable
• Inspiratory
• Inviolable
• Kinesthetic
• Laterigrade
• Legitimate
• Linguistic
• Macroscian
• Marionette
• Megohmmeter
• Millimeter
• Negligible
• Nonsensical
• Noteworthy
• Obsolescent
• Ontological
• Orismology
• Parapetless
• Parvanimity
• Pentameter
• Peremptory
• Permanence
• Persuasion
• Platypodia
• Pococurante
• Recitative
• Rectigrade
• Refocillate
• Regenerate
• Relational
• Rheostatic
• Significant
• Superimpose
• Theretofore
• Transversal
• Troposphere
• Vinaigrette
• Xenogenetic

How to Study This List Effectively

With seven fairly even categories of 25 words each, plus a 50-word final category, the most sustainable pace is one category a day rather than compressing the whole list into a weekend. The Latin & Greek Word Roots category is worth extra time relative to its size — words like "autochthon" and "axiomatic" look intimidating until the roots are broken apart, and that same root-recognition skill carries directly into the longer, final category too. Always spell out loud rather than silently, since seventh-grade bees are oral competitions, and don't let a category go untouched for more than a week — a short review pass keeps it from slipping back out of memory.
