Answer:
The use of decasyllabic meter
Geoffrey Chaucer was an English poet during the Middle Ages, best known for his work The Canterbury Tales. He is known as the "Father of English literature" and was the first writer to be buried in Poets' Corner of Westminster Abbey.
Chaucer is also well-known for his metrical innovation. He was one of the first English poets to use the five-stress line, which is a decasyllabic cousin to the iambic pentameter that became popular during the Elizabethan period.
I have read "The Things They Carried" by Tim O'Brien. This story is a fictional story about a young man who was drafted for the Vietnam war in his first years of college. This book describes the coming of age of multiple characters in its portrayal of each character individualistically. It shows how fast each of these young men had to grow up after joining the war and the difficulties they faced. It is easy to forget how young these guys are because of the things they say or the actions they must take. There are many moments in the book that make you stop and go "Hey wait. These are just kids," and it really shows the maturing process and the stresses of war in addition to suddenly being thrust into adulthood.
