Iceberg is the writing style of Hemingwat. Influenced by his journalistic career, Hemingway contended that by omitting superfluous and extraneous matter, writing becomes more interesting. He summarized his theory:
If a writer of prose knows enough of what he is writing about he may omit things that he knows and the reader, if the writer is writing truly enough, will have a feeling of those things as strongly as though the writer had stated them. The dignity of movement of an ice-berg is due to only one-eighth of it being above water. A writer who omits things because he does not know them only makes hollow places in his writing.
