The sentence in the above excerpt from "In Another Country" by Ernest Hemingway which is an example of irony is:
“You are a fortunate young man.”
The story "In Another Country" is about Hemingway's personal experiences in the Milanese hospital. He narrates the stories of the patients admitted with him after the end of the first World War. The story talks about the wounds which the war has given to them, apart from the physical pains. The wounded soldiers wanted to erase the ills and effects which the world war has given to the world. In the above excerpt, it is ironical that the doctor calls the football player 'a fortunate man' after his leg broke off.
Haven’t done this in a while but I think it’s complex
complex contains an independent clause which includes subject and a verb in that sentence and cannot stand on its own.
Independent clause can stand on its own and makes a complete thought
My best guess would be a gerund phrase because the -ing verb is at the beginning of the sentence, thus making it a noun
