Free indirect speech is also called as free indirect discourse, free indirect style, or discourse indirect libre in French.)
While indirect speech conveys the report in the words of the reporter, with verbs generally 'backshifted' in tense and changes in pronouns and adverbials of time and place are made to align with the time of reporting; free direct speech lacks a reporting clause to show the shift from narration to reporting, it is often used in fiction to represent the mental reactions of characters to what they see or experience.
