What are the most distinguishable textual features of Journalistic style? Is the use of Passive Voice and Indirect Speech is high in this style?
I can only answer the first question; try asking the second one another day.
Matthew Arnold, I believe, said, "Journalism is literature in a hurry." Today, at least in fiction, the godfather of the journalistic style in Ernest Hemingway. It is the rhetoric of ethos: highly ethical because of its lack of moralizing. It is unadorned: Hemingway distrusted adjectives. Overall, its minimalistic and understated style is characterized by the following:
-high frequency words
-1st person pronouns
-action verbs, active tense
-compound sentences (lots of coordinating conjunctions “and”)
-1st Person (I –oriented)
-trustworthiness of the writer or speaker
-stream of consciousness
