Combating vs Combatting: Which Spelling Is Correct?

Combating and combatting are both recognized spellings of the present participle of combat. They have the same meaning: to fight against, oppose, or try to stop something harmful.

For most general writing, combating is the simpler choice. However, combatting is also a documented variant, so seeing the double “t” does not automatically mean the word is wrong.

Combating vs Combatting: What’s the Difference?

The main difference between combating and combatting is spelling, not meaning. Both forms come from the verb combat.

Form	Meaning	Example
Combating	Fighting against or trying to stop something	The group is combating online fraud.
Combatting	Fighting against or trying to stop something	The group is combatting online fraud.

Cambridge Dictionary lists combatting as the present participle of combat, while its entry for combat recognizes both the -t- and -tt- forms.

The American Heritage Dictionary likewise lists combating and combatting as forms of the verb.

What Does “Combating” Mean?

Combating means actively fighting against, resisting, or working to stop a problem.

For example:

• Combating crime means working to reduce or stop crime.
• Combating disease means fighting or controlling a disease.
• Combating misinformation means taking action against false or misleading information.
• Combating poverty means working to reduce poverty.

The verb combat can describe both literal fighting and efforts to deal with serious problems.

Cambridge defines it as trying to stop something unpleasant or harmful from happening or increasing.

What Does “Combatting” Mean?

Combatting has the same meaning as combating. The extra t does not create a different definition.

For example, these sentences mean essentially the same thing:

• The city is combating illegal dumping.
• The city is combatting illegal dumping.

Cambridge provides examples of combatting in contexts involving disease, crime, violence, and other problems.

Why Are “Combating” and “Combatting” Both Used?

The confusion comes from English spelling rules for adding -ing to verbs.

In some words, the final consonant is doubled before -ing:

• run → running
• stop → stopping
• admit → admitting
• begin → beginning

But consonant doubling is not a rule that works identically for every verb. Established word forms and pronunciation also matter.

With combat, dictionaries recognize both combating and combatting. Merriam-Webster’s Scrabble dictionary, for example, lists combating and combatting as forms of combat.

The -ing Spelling Rule

A common spelling rule says that a final consonant is often doubled when a short vowel comes before it and the relevant syllable carries the stress.

For example:

• plan → planning
• sit → sitting
• prefer → preferring

However, combat does not fit neatly into a simple one-line rule. Trying to decide the spelling only by counting letters can lead to mistakes.

That is why the safest approach is to recognize combating and combatting as established variants rather than treating the spelling as a change in meaning.

A Note About Regional Spelling

Regional conventions can affect which form a writer encounters more often. Combating is widely used in U.S. writing, while combatting is also well established, particularly in some British usage.

The important point is that both forms can be found in reputable English references. Cambridge and American Heritage both document the two forms.

Combating vs Combatting Examples

Seeing the two spellings in real sentences makes the difference easier to understand.

Combating vs Combatting Examples

With “combating”	With “combatting”
We are combating cybercrime.	We are combatting cybercrime.
New programs focus on combating fraud.	New programs focus on combatting fraud.
The organization is combating food insecurity.	The organization is combatting food insecurity.
Scientists are combating infectious diseases.	Scientists are combatting infectious diseases.
The campaign focuses on combating misinformation.	The campaign focuses on combatting misinformation.

Both versions express the same basic idea. The choice is about the spelling form you want to use, not a difference in the action being described.

Common phrases with combating include:

• combating crime
• combating fraud
• combating disease
• combating poverty
• combating climate change
• combating misinformation
• combating corruption
• combating cybercrime
• combating addiction

These phrases use combat in its broader sense of opposing or working to reduce a problem rather than physically fighting an opponent.

Which Spelling Should You Use?

If you are writing general U.S.-focused content, combating is a straightforward choice.

It is familiar, concise, and widely recognized. It also avoids unnecessary confusion for readers who expect the single-t spelling.

Use combatting when you are following a particular publication’s established spelling, quoting a source, or maintaining consistency with a style that uses that form.

The most important rule is consistency. Do not switch randomly between combating and combatting within the same piece of writing.

A simple memory tip is:

combat + ing = combating

When in doubt, combating is the practical spelling to choose for ordinary U.S. writing.
