Attentive is defined here as heedful; regardful; full of attention. Affection can be described as passion of any kind, and it's followed by the third definition that reads "love, kindness, good-will to some person".

This definition is from the the 1775 Johnson Dictionary. This dictionary is the same one that Austen used, and this is why this would show the significance of the word "attentive" in this context.

"The fashionable carriage now is a curricle, and the most elegant of that fort is one built by." Times [London, England] 2 Aug. 1787: 3. The Times Digital Archive. Web. 25 Apr. 2017.

This carriage was deemed to be one of the fashionable ones; this could only shed good light on Willoughby and alludes to his class and his fashion style. It was deemed to be an elegant mode of transportation, which helps contribute to the Dashwoods' impression of Willoughby.

The first dictionary definition indicates that it is "a disease suppose to proceed from a rebundance of black bile." The second definition reads "a kindness of madness, in which the mind is always fixed on the object". We see this afflict Marianne throughout the duration of the novel, but the third recorded definition fits Colonel Brandon best: "A gloomy, pensive, discontented temper". This word was more frequently used as a noun, not an adjective.

This stood out to me, because although sense and sensibility are the prevailing themes in this book, I believe that Austen also had a lot to say about gossip, and its harmful effect within society. Here, we see the worst gossiper relish in her acquired information, though she was in no position to do so, and she decides to share this piece which is not hers to share.

I believe this shows remarkable character development. Elinor is no longer suppressing her true feelings, and is confessing them to her sister. She is gaining more sensibility while still holding onto her sense.
