The act of asking questions to get information or to investigate something.

Interrogation → It is formed from "inter-" (meaning between) and "rogare" (meaning to ask). The word describes the act of asking questions, often in a formal or intense manner, typically involving multiple inquiries between parties.
Think of asking questions 'between' people ('inter-') — that's why interrogation means to ask questions in detail.
