“”You must,” the Reverend Mr. Pleasant Green would say unctuously, “trust the Lord more fully, Helga.” This pabulum did not irritate her.” (277, online version)

Understanding this word tells us that the way how Reverend Mr. Pleasant Green was talking to Helga in a way to persuade her to trust more in God was acceptable in her mind. She was willing to allow his spiritual talk to move her to see what he was saying was the right way even though she looked and believed in not trusting God so much.

“”You must,” the Reverend Mr. Pleasant Green would say unctuously, “trust the Lord more fully, Helga.” (277 online version)

Finicky (adjective) – extremely or excessively particular, exacting, or meticulous in taste or standards

https://www.merriam-webster.com/dictionary/finicky

“In the certainty of his goodness, his righteousness, his holiness, Helga somehow overcame her first disgust at the odor of sweat and stale garments. She was even able to be unaware of it. Herself, Helga had come to look upon as a finicky, showy thing of unnecessary prejudices and fripperies.” (271-272 online version)

Understanding this meaning tells us that Helga was able to focus on exactly what she wanted to focus on which was the admiration of the man and was able to block out the disgusting smell of sweat and stale clothes.

Clamor (noun) – noisy shouting

https://www.merriam-webster.com/dictionary/clamor

“And in that moment she was lost-or saved. The yelling figures about her pressed forward, closing her in on all sides. Maddened, she grasped at the railing, and with no previous intention began to yell like one insane, drowning in every other clamor, while torrents of tears streamed down her face.” (254, online version)

This word kind of paints a picture of how she was yelling/crying by showing us that the yell would start off loud and then slowly began to get lower and lower. Once it’s low then tears will begin to fall down her face and then the yelling/shouting/crying will begin again at the loudest to gradually lower.

Aghast (adjective) – shocked and upset

https://www.merriam-webster.com/dictionary/aghast

“James was aghast. He forgot to be embarrassed. “But Helga! Good heavens! Don’t you see that if we-I mean people like us-don’t have children, the others will still have. That’s one thing that’s the matter with us. The race is sterile at the top” (231, online version)

The word ‘aghast’ tells us how James facial reaction was towards Helga’s response. It shows that he was not expecting Helga, who wants black people to be appreciated, so he thought she would have kids with another black man like him. But was not the case so it took him by surprise and thought that she didn’t understand the importance of it.
