To question someone formally, systematically, and often aggressively, typically as part of an official investigation.

Implies an imbalance of power, such as police questioning a suspect or military officers questioning a prisoner.

The story behind the word. The word travels back to the Roman legal system, where 'interrogare' meant to formally question a witness or defendant. The prefix 'inter-' suggests a back-and-forth exchange, while 'rogare' is the same root that gives us arrogant (claiming too much for oneself) and prerogative (a special right asked for). Over the centuries, it retained its heavy, official, and slightly intimidating atmosphere.
