What Does “Rancor” Mean?

Simple Definition

Rancor means a strong feeling of hate or anger that lasts for a long time.

It is not a small or short-term anger. It is deep, long-lasting, and often comes from past problems or hurt.

When to Use It

Use rancor when:

• Someone cannot forgive a past mistake
• There is long-term bitterness
• Emotions are strong and negative

This word is more common in American English.

Grammar Rule

• “Rancor” is a noun
• It is usually uncountable
