A writer's literary style consists mainly of the words he uses and the order he puts them in. That's called, respectively, diction and syntax. In terms of word selection, a pompous or insecure writer will use "multiple" instead of "many"; "impacted by" instead of "affected"; and "individual" instead of "person." Such a writer also uses many more words than necessary. Regarding syntax, an academic author might write: "A good time was had by all." A so-called "literary" novelist might say it this way: "By all, a good time was had." An author with readers will write: "We had a blast."
