From page 3, first paragraph: ” I am sitting by the window now, up in this atrocious nursery,and there is nothing to hinder my writing as much as I please, save lack of strength”.
The word nursery gave away the meaning of the word. It helped me understand what the word atrocious meant. I now understand that the narrator was decribing the nursery as horrifying. The nursery was of very poor quality that it effected her ability to write.
