Haastatteluna
Haastatteluna is a Finnish term used to indicate that a text or segment is presented in the form of an interview. It derives from the noun haastattelu (interview) plus the translative suffix -na/-nä, which signals a role, function, or mode of presentation, effectively meaning “as an interview.”
In practice, haastatteluna describes the format rather than the subject matter. It is commonly used in journalism,
Grammatical notes: Haastatteluna is used with a copula to describe the format, as in artikkeli on haastatteluna
