What Does “Rancor” Mean?

Rancor is a noun that refers to deep, long-lasting resentment, bitterness, or hostility toward someone or something.

Someone experiencing rancor may:

Hold a grudge for years.
Feel bitterness whenever the other person is mentioned.

Rancour naturally follows the same spelling pattern.

Rancor vs. Rancour: What’s the Difference?

At first glance, the two spellings may seem to represent different words. In reality, they are simply regional spelling variants.

Spelling Is the Only Difference

Everything about the words is identical except the spelling.

Both words:

Describe the same emotion.
Function as nouns.
Have the same pronunciation.
Share the same origin.
Carry the same emotional intensity.

The choice depends entirely on whether you’re writing in American English or British English.

American English vs. British English

American English generally favors -or endings.

British English typically retains -our endings inherited from French.

Here are several familiar examples.

American English	British English
Color	Colour
Honor	Honour
Favor	Favour
Labor	Labour
Humor	Humour
Neighbor	Neighbour
Rumor	Rumour
Valor	Valour
Candor	Candour
Rancor	Rancour

This pattern explains why both spellings exist today.

Which Countries Use Each Spelling?

Your audience should determine your spelling choice.

Country	Preferred Form
United States	Rancor
United Kingdom	Rancour
Australia	Rancour
New Zealand	Rancour
Ireland	Rancour
Canada	Usually Rancour, depending on the publication’s style

If you’re writing for an international audience, choose one variety of English and use it consistently throughout your document.

Why Both Spellings Exist

The spelling difference traces back to the early nineteenth century.

British English retained traditional French-influenced spellings ending in -our.

American English adopted simpler -or spellings through the influence of lexicographer Noah Webster, who believed American spelling should be more consistent and easier to learn.

His spelling reforms affected hundreds of words, including:

Colour → Color
Honour → Honor
Labour → Labor
Rumour → Rumor
Rancour → Rancor

Although the spellings changed, the meanings remained exactly the same.

Conclusion

Understanding the difference between rancor vs. rancour is easier than it first appears. Despite their different spellings, they are the same word with the same meaning.
