Rancor vs. Rancour – What’s the Difference?

Rancor vs. Rancour – What’s the Difference? The short answer is simple: American and British English share the meaning, not the spelling, and that difference matters in writing.

In English, this word keeps the same definition and what it denotes, even as the variant, version, or form changes: rancor (American) and rancour (British), both from a Latin root shaped by history, origin, region, culture, and geography. From a language and dialect view, the sound and tone are identical, describing deep, long-lasting, anger, bitterness, resentment, and ill-will across contexts.

The distinction is subtle, tiny, yet important; the choice depends on usage, audience’s preference, and conventions. In my teaching abroad, I’ve helped learners, students, teachers, native speakers, and critics decide the correct spelling by exploring examples, texts, sentences, idiomatic expressions, and common mistakes from guides, dictionaries, and notes, improving clarity, coherence, communication, and confidence as English keeps evolving.

Definitions

Understanding rancor vs. rancour starts with clear definitions. Although they are essentially the same in meaning, the spelling and regional usage differ.

Rancor

Rancor is the preferred spelling in American English. It describes deep, long-lasting resentment or bitterness, often tied to past conflicts or personal grudges. It carries an emotional weight that signals more than casual annoyance.

Example sentences:

• She felt deep rancor toward her colleague after the promotion was denied.
• The negotiations ended in rancor and hostility, leaving both sides unwilling to compromise.

Rancour

Rancour is the British English variant of rancor. Its meaning is identical: persistent bitterness or resentfulness. Writers in the UK, Australia, Canada, and other countries following British English norms will often prefer this spelling.

Example sentences:

• He harboured rancour for years after the legal dispute.
• Despite apologies, the rancour between the two families remained strong.

Origins and Etymology

To fully understand rancor vs. rancour, it helps to explore their roots.

Both words trace back to the Latin verb “rancere”, which means “to stink” or “to be rank.” In classical Latin, rancor referred to the figurative “foulness” of bitterness or resentment. Over centuries, this meaning transitioned into Old French as rancor, before arriving in Middle English as rancour.

The divergence in spelling occurred largely due to American English simplification. Like “color” instead of “colour” or “honor” instead of “honour,” Americans streamlined the spelling to rancor for ease and consistency.

Timeline of spelling evolution:

Year/Period	Event
1st century AD	Latin “rancere” meaning “to stink”
12th–13th century	Old French “rancor” enters Middle English
15th century	British English solidifies “rancour” spelling
19th century	American English simplifies to “rancor”
