The Quick Answer
If you are looking for the correct spelling, here it is: Aggression is the only correct spelling in standard English.
The word requires two "g"s and two "s"s (A-G-G-R-E-S-S-I-O-N). Spelling it as "agression" with a single "g" is universally considered a grammatical error in professional, academic, and casual writing. If you struggle with this word, you are not alone—it is one of the most frequently misspelled words in the American English language.
Correct Spelling
The definitive way to write this word.
A-G-G-R-E-S-S-I-O-N
Take note of the double "G" and the double "S". This is the only accepted spelling in both American and British English dictionaries.
Common Misspellings
The most frequent errors writers make.
Agression
Missing the second "g". The most common error.
Aggresion

Agresion
Missing both double letters. A severe spelling error.
Why Is This Word Misspelled?
The linguistic breakdown of a notorious spelling trap.
The confusion stems from a clash between English spelling rules and English pronunciation. When we speak the word "aggression," we pronounce the "gg" as a single, hard "g" sound. Because our brains associate a single sound with a single letter, our hands naturally want to type a single "g".
The Phonetic Trap
Spoken: uh-GRESH-un. The double "g" blends into one sound, tricking the ear into thinking there is only one consonant.
The Etymological Rule
Written: A-G-G-R-E-S-S-I-O-N. The Latin root demands the double consonant, regardless of how it sounds when spoken.
Correct Spelling Breakdown
Analyzing the word syllable by syllable.
ag
Prefix (from Latin 'ad-')
gres
Root part 1 (from 'gradi' meaning 'to step')
s
Root part 2 (connecting consonant)
sion
Suffix (noun ending)
Notice how the prefix "ag-" ends in "g" and the root "gres-" begins with "g", creating the double "g". The suffix "-ion" requires a double "s" to maintain the correct stress and short vowel sound.
Spelling Pattern
The Latin assimilation rule at work.
To understand why the double letters exist, we have to look at Latin. The word comes from the Latin verb aggredi, which translates to "to approach" or "to attack." It is built from two parts: the prefix ad- (meaning "to" or "toward") and the root gradi (meaning "to step" or "to go").
When the "ad-" prefix attaches to a root starting with "g", it assimilates and becomes "ag-", giving us the first double "g". The word then transitions into the noun form "aggression" by adding the suffix "-ion." To maintain the short "e" vowel sound in "gres" before the suffix, English spelling rules require the double "s". Therefore, to spell aggression correctly, you must include both the double "g" and the double "s".
Noah Webster, the father of American English spelling, intentionally simplified many words (like dropping the "u" in "colour"), but he left "aggression" alone because its Latin roots and phonetic rules required the double consonants to retain their structural meaning.

2. The "Go Get" Trick
Think of an aggressor saying "Go Get them!" Both "Go" and "Get" use G, giving you your double G to start the word.
3. The "Double Double" Pattern
Visualize the word as a pattern of doubles. GG and SS. If you type it out, let your fingers double-tap the "g" and double-tap the "s" in a rhythmic fashion: A [tap-tap] RE [tap-tap] ION.
4. The "Stress" Trick
Because aggression causes Stress, the word requires a double "S" to represent the word Stress. Pair this with the double G for Great force, and you have the full formula.

Frequently Asked Questions
Quick answers to common questions.
Is 'agression' ever an accepted spelling?
No. In both American and British English, 'agression' is universally considered a misspelling. It is never accepted in formal writing, academic papers, or professional publications. The only correct spelling is 'aggression' with two 'g's and two 's's.
Why do people misspell it as 'agression'?
The primary reason is phonetic. When spoken, the double 'g' in the middle of 'aggression' blends into a single, hard 'g' sound. Because English is largely phonetic, writers naturally drop the second 'g' to match what they hear.
What is the best memory trick for this word?
The best mnemonic is: 'Aggression requires Great force, so it needs a double G for Great. It causes Stress, so it needs a double S for Stress.' This ties the spelling directly to the word's meaning.
Is 'aggression' spelled differently in the UK?
No. Unlike words such as 'color/colour' or 'center/centre', no spelling reform was applied to 'aggression.' It is spelled with two G's and two S's on both sides of the Atlantic.
What is the verb form of aggression, and how is it spelled?
The verb form is 'aggress.' It retains the double 'g' from the root. However, it is rarely used in modern conversational English, having largely been replaced by 'attack' or 'confront.'
What is the origin of the word aggression?
It comes from the Latin verb 'aggredi', which means 'to approach' or 'to attack.' It is formed from the prefix 'ad-' (to/toward) and 'gradi' (to step). The assimilation of 'ad-' to 'ag-' gives us the first double 'g'.
How do you use aggression in a sentence?
You use it as a noun when describing hostile behavior or forceful action. For example: 'The dog showed aggression toward strangers' or 'The UN condemned the unprovoked act of military aggression.'
Is aggression a formal word?
Yes, it is considered a formal and professional word. It is highly appropriate for academic writing, legal documents, and journalism, sounding much more precise than informal synonyms like 'anger' or 'meanness.'
Does aggression have a prefix and a root?
Yes. The prefix is 'ag-' (a variation of 'ad-' meaning 'to' or 'toward'), and the root is 'gradi' (meaning 'to step' or 'to go'). Together, they literally mean 'to step toward' someone aggressively.
Can aggression ever be a positive trait?
Yes, in certain contexts. In sports and business, 'controlled aggression' is often viewed as a positive trait, referring to high energy, assertiveness, and a proactive drive to succeed, rather than literal violence.
