The English language nouns Passion and Compassion have related meanings, but they are different, as I shall explain, using British English examples.
Passion is a strong emotional feeling, which can be romantic or a compelling liking for something, or an overwhelming interest in something, such as a sport, hobby, way of living, or thinking. It can sometimes even be violent emotion.

Passionate (adjective) describes the strong attraction or emotion towards something.

Compassion is the concern or pity shown towards someone or a group or cause that is suffering or has misfortune. Someone showing compassion will act in the sufferer's best interests, for example by giving practical or emotional support, making them feel worthwhile, protected, secure and loved
