Dinterrogatoire
Dinterrogatoire is a term that does not have a widely recognized definition in English-language or French reference works. In many uses it appears to be a concatenation of the French preposition de (often contracted as d’) and the noun interrogatoire, which means interrogation or questioning. In standard French, d’interrogatoire would function only within a larger phrase; written as a standalone term it is not idiomatic, and dinterrogatoire without an apostrophe is generally treated as a misspelling or nonce word. Because there is no established meaning, the interpretation of dinterrogatoire depends on context. It may reflect a typographical error, a stylistic neologism in a creative text, or a domain-specific shorthand in a particular publication.
When encountered in scholarly or professional writing, it is prudent to seek clarification from the author
