Structure and Figures of Speech (My Other Two)

I tied these two together because they relate to each other.

Structure
At first the structure is rigid and precise in the use of words, sentences, etc. However, as the book progresses, the style of D-503's entries becomes more of a flowing stream of consciousness than the orderly way he had it before. He also uses many more...

Figures of Speech

Many of the figures of speech D-503 ends up using is either related to other people he knows and their facial features (O's rosy crescent mouth and I's triangular eyebrows [Note that there is still geometry present]) or nature, such as his recurring thoughts about the birds.
