in some articles sense is associated with elinor and being reserved and sensibility with being overly emotional. in other articles, it's the other way around. Who is right?

Sensibility is Marianne who is overly emotional and passionate. It also refers to someone who has bad judgment, such as Marianne. Elinor is all sense because she holds back and knows what is proper and what isn't.

I can't tell the difference between Jane Austen novels. They are all like "Hi, I is unmarried girl and oh I want to get married nao."
