Some of the hardest words to understand during my Sense and Sensibility Reading:

Because the Sense and Sensibility novel is written in an Ancient British English, some words could represent a big deal by the time we are reading it, so I consider that is important to find those definitions in a Dictionary in order to get a better understanding,  for instance:

To remain: To continue in the same place, state or position.

Beyond: After or later than

                -Farther along or away

Impoverishing: To reduce, to poverty.

To neglect: To pay little or no attention to.

Indeed: Without a doubt

                -Certainly

Afterwards: After an earlier event or time

                      -Subsequently

Claims: A demand for something as rightful of due

Acquaintance:  Knowledge of a person acquired by a relationship less intimate than friendship. 

Trifling: Frivolous or idle.

Grandeur: The quality or condition of being grand; magnificence

Unanimous: Sharing the same opinions of views.
