What does 'rancor' refer to?

The term 'rancor' specifically denotes a feeling of deep and bitter anger, typically accompanied by resentment or ill will towards someone. It often arises from a sense of betrayal or lingering grievances. In interpersonal contexts, it can indicate a prolonged emotional state where one harbors hostility. Recognizing 'rancor' as an intense, often long-lasting emotion helps differentiate it from other terms related to feelings or conditions, which do not capture the same essence of bitterness and animosity present in this word. This precision in understanding emotional vocabulary is essential, especially in contexts that discuss human relationships and conflicts.
