Verité
This is literally French for “truth,” but it’s taken on a media context. “Cinema verité” is a style of filmmaking noted for realism.
From Brittanica:
a French film movement of the 1960s that showed people in everyday situations with authentic dialogue and naturalness of action.
The word “verité” on its own has become a reference to accuracy and attention to detail.
Why I Looked It Up
From Spooked:
Ian also believed in verité when it came to fostering illusions, so people making pretext calls from his agency worked out a special room equipped with tape recorders that played background noise suitable to the identities they had assumed that day.
