If you have ever paused halfway through a sentence wondering whether to type “combating” or “combatting,” you are not alone. This is one of the most common spelling mix ups in English, and it trips up students, journalists, and even seasoned editors. The good news is that once you understand the simple rule behind it, you will never second guess yourself again.
Both spellings are technically correct. The version you should use depends almost entirely on your audience and the style of English you are writing in. In this guide, you will learn exactly when to use each form, why the difference exists in the first place, and how to apply the rule confidently in your own writing.
Combating or Combatting: Understanding the Root Word “Combat”
Before comparing the two spellings, it helps to look at where they come from. Both words trace back to the verb “combat,” which means to fight against something or to actively work to stop, reduce, or prevent a problem.
You will see “combat” used in two main ways:
- As a noun: “The soldiers were engaged in intense combat.”
- As a verb: “Local leaders are working to combat homelessness.”
Since combat is a verb, English grammar requires it to take an “ing” ending whenever it describes an ongoing action, such as in a continuous tense or as a gerund. That single “ing” ending is where the entire debate begins, because English has two competing traditions for how to spell verbs like this.
Why Both Spellings Exist
The reason combating and combatting both appear in modern writing comes down to a difference in spelling conventions between American and British English. This is the same kind of split you see in pairs like color and colour, or realize and realise.
American English tends to follow a more predictable, rule based approach to adding suffixes. British English, on the other hand, often holds onto older spelling habits that developed before modern stress based rules were standardized. Neither version is “wrong.” They are simply two branches of the same language that evolved along slightly different paths.
Combating in American English
✔️ Correct in American English: combating
In the United States, “combating” is the standard and widely accepted spelling. It follows a well established rule in American English for adding “ing” to two syllable verbs.
Here is the logic behind it. When a verb has more than one syllable, English usually doubles the final consonant before adding “ing” only if the stress falls on the last syllable. The word combat is pronounced with the stress on the first syllable, like COM bat, not com BAT. Because the stress does not land on the final syllable, American spelling rules say the final “t” should not be doubled.
That is why style guides such as AP, APA, and MLA all favor combating, and why you will see it consistently across American newspapers, academic journals, and professional publications.
❌ Usually incorrect: combatting
While combatting is not a made up word, it is generally treated as incorrect or nonstandard in American writing. If you are writing for a US based audience, a school assignment, or any content following American style guides, combatting will likely be flagged as a spelling error.
Combatting in British English
Acceptable in British English: combatting
In the United Kingdom and many Commonwealth countries, combatting is a recognized and acceptable spelling. British English has historically been more generous with consonant doubling, sometimes applying it even to words where the stress pattern would not require it under American rules.
This tendency shows up in other British spellings too, such as travelled versus traveled, or cancelled versus canceled. In each case, British English doubles the consonant more readily than American English does.
Also acceptable: combating (used but less common)
Interestingly, combating is not considered wrong in British English either. It appears regularly in UK publications, government documents, and academic writing, though it is somewhat less common than combatting. Many modern British style guides now accept both forms, which means the gap between the two dialects is narrower than it might first appear.
How Pronunciation Affects Spelling
Spelling in English is often tied more closely to sound than people realize, and this word is a textbook example.
Stress pattern:
- Combat is pronounced with stress on the first syllable: COM bat.
- Because the stress does not fall on the final syllable, standard doubling rules in American English say you should not double the trailing consonant.
- British spelling conventions do not always follow this stress based logic as strictly, which is part of why combatting persists there.
Compare this to a word like “forget,” where the stress does fall on the second syllable (for GET). That stress pattern is why “forgetting” correctly doubles the “t” in both American and British English. Combat behaves differently because of where its emphasis naturally falls.
Understanding “Combating” and “Combatting” as Verb Forms
Regardless of which spelling you choose, both words serve the exact same grammatical purpose. They are simply two different spellings of the same verb form.
Present participles
As present participles, both words describe an action that is currently happening or ongoing.
- “The health department is combating the spread of the virus.”
- “Officials are combatting rising crime rates in the city.”
Gerunds
Both spellings can also function as gerunds, meaning they act like a noun in a sentence.
- “Combating misinformation requires a coordinated effort.”
- “Combatting food insecurity remains a top priority for the charity.”
In both roles, the meaning stays identical. Only the spelling changes based on regional preference.
Real-World Usage Examples
American Context
In the United States, combating shows up consistently across formal and everyday writing:
- “The CDC has released new guidelines for combating seasonal flu outbreaks.”
- “Small businesses are combating rising costs by adjusting their pricing models.”
British Context
Across the UK, you will often see combatting used in similar situations:
- “The council announced a new strategy for combatting anti social behavior.”
- “Charities are combatting loneliness among elderly residents through community programs.”
Both sets of examples describe the same kind of ongoing effort. The only real difference is the spelling convention tied to the writer’s region.
Case Study: Combating Climate Change vs Combatting Climate Change
Climate related writing is one of the clearest places to see this regional split in action, since the topic appears constantly in research, journalism, and policy documents worldwide.
US Environmental Research Paper
American researchers and institutions almost always publish using combating. A typical example might read: “This study outlines several strategies for combating climate change through renewable energy adoption and reduced emissions.” This phrasing aligns with US academic conventions and is what you would expect from a journal following APA or MLA formatting.
UK Government Report
A British government report on the same subject is more likely to use the double t spelling. For instance: “The department remains committed to combatting climate change through sustainable transport reforms and updated environmental policy.” This reflects the spelling conventions commonly used by UK institutions and publications that follow British style guides.
Historical Development of Both Spellings
The split between combating and combatting did not happen overnight. It developed gradually as American and British English drifted apart in the eighteenth and nineteenth centuries.
Key historical influences:
- American spelling reform, largely shaped by lexicographer Noah Webster, pushed for simpler, more phonetic, and more rule consistent spellings.
- British English retained many older spelling habits from earlier centuries, including a stronger tendency toward consonant doubling.
- Print culture and dictionaries on each side of the Atlantic reinforced these differences over time, cementing combating in America and combatting in Britain.
- Modern globalization and digital publishing have blurred the lines somewhat, which is why you now see some overlap between the two regions.
How to Choose the Correct Spelling
Choosing the right spelling really comes down to knowing your audience and the style guide you are following.
✔️ Choose combating if:
- You are writing for an American audience.
- You are following AP, APA, MLA, or Chicago style.
- Your content targets a global or international readership.
- You want the spelling that is more widely recognized online.
✔️ Choose combatting if:
- You are writing specifically for a British or Commonwealth audience.
- Your publication follows Oxford or Cambridge style conventions.
- You are matching the spelling used elsewhere in a British English document.
Bonus Tip
When in doubt, default to combating. It is accepted in both American and British English, it matches most global style guides, and it is far less likely to be flagged as incorrect by spell checkers, editors, or academic reviewers.
Common Consonant Doubling Rules
Understanding the broader rule behind this spelling issue makes it much easier to handle similar words in the future.
Double the final consonant when:
- The verb is one syllable and ends in a single vowel followed by a single consonant, such as run becoming running.
- The verb has more than one syllable and the stress falls on the last syllable, such as admit becoming admitting.
Do NOT double when:
- The verb ends in two consonants, such as help becoming helping.
- The verb ends in two vowels followed by a consonant, such as read becoming reading.
- The verb has more than one syllable and the stress falls earlier in the word, such as combat becoming combating.
Table: Comparison of Consonant Doubling
| Word | Stress Pattern | American Spelling | British Spelling |
|---|---|---|---|
| Combat | First syllable | Combating | Combatting |
| Forget | Second syllable | Forgetting | Forgetting |
| Travel | First syllable | Traveling | Travelling |
| Admit | Second syllable | Admitting | Admitting |
| Cancel | First syllable | Canceling | Cancelling |
This table shows a clear pattern. When the stress falls on the last syllable, both American and British English agree on doubling. When the stress falls earlier in the word, the two dialects often part ways, and combat is one of the clearest examples of that split.

Conclusion
Combating and combatting mean exactly the same thing and both are grammatically valid, but they belong to different sides of the English speaking world. Use combating if you are writing in American English or aiming for a broad, international audience, and reach for combatting when your writing follows British English conventions. When you are unsure which audience you are addressing, combating is the safer, more widely recognized choice. Once you understand the stress pattern behind the rule, you will never have to guess again.
