Combating vs Combatting: both spellings are correct. Major dictionaries list both as -ing forms of the verb combat. Most writers choose combating, the one-t form, because it’s simpler and widely recognized. Combatting isn’t a typo, though. It’s an accepted variant, and some publishers prefer it. The extra t changes nothing about meaning or sound. Pick one form and keep it consistent.
Combating vs Combatting trips people up because English doubling rules aren’t tidy. You’ll see what major dictionaries say and how stress shapes each spelling. You’ll also get real examples, a simple way to choose, and short answers to common questions. Examples cover news, health, and policy writing. By the end, you’ll know which form fits your readers and why the other one still exists.
Quick Answer:
Both are correct. Combating (one t) is the safer default for most readers. Combatting (two t’s) is an accepted variant listed in major dictionaries. Neither changes the meaning. Example: “The city is combating air pollution.” Pick one spelling and use it consistently.
Combating or Combatting: Understanding the Root Word “Combat”
Combat has a long history. English borrowed it in the mid-1500s from French combattre. That verb came from late Latin. Its parts meant “together with” and “to fight.”
Today, combat works as both a noun and a verb. The noun means fighting, usually in war: “The soldiers had never seen combat.” The verb means working to stop something harmful. That verb is where the spelling question starts, because its -ing form takes one t or two.
Combating meaning
Combating means taking action to stop, reduce, or prevent something harmful. People combat crime, disease, fraud, and misinformation. The word suggests an active, urgent effort. Close synonyms include fighting, tackling, and countering. Addressing is a softer option.
Two look-alikes cause trouble. A combatant is a person who fights. Combative is an adjective for someone ready to argue. Neither one is a spelling variant of combating.

Why Both Spellings Exist
English doesn’t double every final consonant before -ing. Some verbs do: stop becomes stopping. Others don’t: visit becomes visiting. Stress usually decides, and dictionaries list two stress patterns for the verb combat. That’s the root of the split.
Neither spelling replaced the other. Both sit side by side in current references.
Combating or combatting Oxford dictionary
Oxford’s learner dictionaries list both -ing forms under the verb combat. The British edition gives combated as the past form. The American edition gives combated and combatted. Merriam-Webster and Dictionary.com list both pairs too.
| Dictionary | -ing forms listed | Past forms listed |
| Merriam-Webster | combating, combatting | combated, combatted |
| Oxford Advanced Learner’s | combating, combatting | combated |
| Oxford Advanced American | combating, combatting | combated, combatted |
| Dictionary.com | combating, combatting | combated, combatted |
No major entry marks combatting as an error. That matters, because some online guides call it one. Compare that with a pair like contractor vs contracter, where one form is a plain misspelling. Combatting sits in a different category. It’s a real variant.
Combating in American English
American dictionaries list both forms. Merriam-Webster places the one-t forms first. Oxford’s American edition lists both too. So US writers can use either, but combating is the natural default.
The one-t form reads cleanly in everyday writing:
- Public health teams are combating the flu.
- Combating misinformation takes steady effort.
- The bank is combating card fraud with new alerts.
An editor may still keep combatting inside a quotation or a proper name. Leave it exactly as the source printed it.
Combatting in British English
Many guides say British English prefers combatting. The evidence is thinner than that claim suggests. The Oxford Advanced Learner’s Dictionary, a British publication, lists both -ing forms. Its past form is combated, with one t.
Combatting or combating UK
In the UK, both spellings are in use. The safest rule is to follow the publication you write for. Don’t guess from other British habits, either. British English often doubles a final l, as in travelled. That pattern ignores stress, so it doesn’t predict anything about t. Readers who want the full l rule can compare canceled or cancelled.
Both of these sentences are correct in British English:
- The council is combating rising damp in older homes.
- The council is combatting rising damp in older homes.
Combatting or Combating: How Pronunciation Affects Spelling
Pronunciation explains the split. Many verbs double a final consonant when three things are true. The word ends in one vowel plus one consonant. The stress falls on the last syllable. And the ending starts with a vowel, like -ing.
Merriam-Webster gives the verb two stress patterns: kuhm-BAT and KOM-bat. Oxford’s American entry does the same. Stress on the last syllable matches permit, which gives permitting. Stress on the first syllable matches limit, which gives limiting. Combat fits both patterns, so it has both spellings.
The extra t doesn’t add a sound. Both spellings are said kuhm-BAT-ing or KOM-bat-ing. The a is short, like the a in cat. It’s not the long a of date.
Quick Comparison: Stress-Based Spelling Rules
| Verb | Stress | -ing form | Why |
| permit | per-MIT | permitting | Last syllable stressed |
| begin | be-GIN | beginning | Last syllable stressed |
| limit | LIM-it | limiting | First syllable stressed |
| visit | VIS-it | visiting | First syllable stressed |
| combat | kuhm-BAT | combatting | Last syllable stressed |
| combat | KOM-bat | combating | First syllable stressed |
Understanding “Combating” and “Combatting” as Verb Forms
Combat is a regular verb, so its forms are easy to predict. Unlike irregular pairs such as drank or drunk, it adds -ed for the past. The only choice is one t or two.
| Form | One-t spelling | Two-t spelling |
| Base form | combat | combat |
| Third person | combats | combats |
| Present participle | combating | combatting |
| Past tense | combated | combatted |
| Past participle | combated | combatted |
Both -ing forms do two jobs. As a present participle, the word follows a form of “be”: Doctors are combating the outbreak. As a gerund, it works like a noun: Combating the outbreak takes teamwork.
Combat also takes a direct object. Most readers find an extra preposition redundant.
Incorrect: Doctors are combating against the outbreak.
Correct: Doctors are combating the outbreak.
Why: The verb already carries the idea of “against.”
Real-World Usage Examples
Both forms turn up wherever people talk about stopping problems. These examples use the one-t spelling. Swap in combatting if your house style prefers it.
Health: Clinics are combating a rise in flu cases.
Policy: Lawmakers are combating tax fraud with new audits.
Environment: Farmers are combating soil erosion with cover crops.
Technology: Engineers are combating spam with better filters.
Education: Schools are combating absenteeism through early outreach.
Notice the pattern. The object is always something unwanted: crime, fraud, poverty, inflation, disease, or climate change.
Common mistakes
Incorrect: Teams are combating fraud and combatting waste.
Correct: Teams are combating fraud and waste.
Why: One document should use one spelling.
Incorrect: She gave a combating reply.
Correct: She gave a combative reply.
Why: Combative describes someone ready to argue. Combating is a verb form.
Case Study: Combating Climate Change vs Combatting Climate Change
Take a phrase that fills reports everywhere: combating climate change. Now write it the other way: combatting climate change. Put the two side by side and compare.
| Feature | Result |
| Meaning | Identical |
| Grammar | Identical: a gerund followed by a direct object |
| Pronunciation | Identical: the extra t adds no sound |
| Dictionary status | Both forms listed |
| Real difference | House style and reader expectation |
Picture an editor at a nonprofit. Her report uses combating on page one and combatting on page nine. Nobody misreads either word. But the mix looks careless, so she picks one form and applies it everywhere.
No measured usage data is quoted here. Frequency counts change with the corpus and the year, and a single percentage can mislead. Dictionary entries and your style guide are steadier guides. Treat combating vs combatting as a style decision, then stay consistent.
Historical Development of Both Spellings
The French verb combattre has a double t. English borrowed it in the 1500s but kept a single t in the base form. The double t may explain why combatting feels natural, since it echoes the French source. That link is plausible, not proven.
The debate isn’t new. A 1973 letter in The Spectator archive shows the same argument. A reader defended combatting with the doubling rule. The editor replied that the Oxford Dictionary and Chambers’s Dictionary then gave only combated and combating. Both put the stress on the first syllable.
Current entries tell a different story. Merriam-Webster and Oxford now list both forms, so the two-t spelling has solid dictionary support today.
How to Choose the Correct Spelling
Use this order when you’re unsure:
1. Check the style guide for your publisher, school, or client.
2. If none names a form, choose combating, the one-t spelling.
3. Match the spelling already used across your site or document.
4. Use one form throughout. Keep quotations exactly as printed.
5. If your spellchecker flags the word, check its language setting first.
A publication’s house style always beats a general rule. That’s true for combating vs combatting and for every other variant spelling.
Combating or combatting AP style
Newsrooms that follow AP style should check the current AP Stylebook entry. A stylebook is the final authority for AP-style copy, so it overrides the default above.
Common Consonant Doubling Rules
The doubling rule helps with dozens of other words. Double the final consonant before a vowel ending when both of these are true:
- The word is one syllable, or its last syllable carries the stress.
- The word ends in one vowel plus one consonant.
Words stressed on the last syllable double: permitting, beginning, and recur, which becomes recurring. Words stressed earlier usually stay single: limiting, visiting, opening. Combat sits in the gray area, because its stress varies.
Some endings never double. The letters w, x, and y stay single: showing, fixing, playing. Words with two vowels before the final consonant don’t double either. Rain becomes raining, and out becomes outing. That’s why outting or outing has a clear answer.
Examples at a Glance
| Base word | -ing form | Reason |
| run | running | One syllable, one vowel plus one consonant |
| recur | recurring | Last syllable stressed |
| begin | beginning | Last syllable stressed |
| visit | visiting | First syllable stressed |
| fix | fixing | The letter x never doubles |
| rain | raining | Two vowels before the final consonant |
| combat | combating or combatting | Stress varies, so both forms exist |

Conclusion
Combating vs Combatting comes down to style, not correctness. Dictionaries list both -ing forms of the verb combat. Combating, with one t, is the safer default for most readers. Combatting, with two, is an accepted variant. Neither changes meaning, grammar, or sound. The difference comes from how stress guides consonant doubling, and the verb has been stressed two ways. Past forms follow the same split: combated and combatted.
Before you publish, check your style guide. If it names a form, use it. If it doesn’t, choose combating and keep it throughout. Mixing both in one document is the main mistake. Remember the Combating vs Combatting rule in one line: either is correct, but consistency isn’t optional. Then move on with confidence.
