Quicksand
Prim – Adj
Passage-
“Quite recently too. Miss MacGooden,
humorless, prim, ugly, with a face like dried
leather, prided herself on being a “lady” from
one of the best families—an uncle had been a
congressman in the period of the Reconstruction. She was therefore, Helga Crane reflected, perhaps unable to perceive that the inducement
to act like a lady, her own acrimonious example,
was slight, if not altogether negative.”
Definition- formally precise or proper, as persons or behavior; stiffly neat.
After reading the definition I understand that the word is used to describe someones behavior. Miss. MacGooden is a proper lady who is rather old and comes from a family with money.
