The phrase "to answer to" means to be responsible or accountable for something. It can refer to a person, group, organization, or even an object that is required to give explanations, provide information, or take responsibility for their actions. The term often implies some level of authority or oversight, such as when a manager "answers to" the CEO of a company, meaning they are responsible and accountable to them. In other contexts, it can refer to something that must respond to commands or requests, like a device "answering to" a user's voice command.
