誰か（だれか、dareka）
- someone

The Japanese word 誰か (だれか) means "someone," "somebody," or "anyone." It refers to an unspecified person or persons. It implies that the speaker doesn't know exactly who they're talking about, or that the identity of the person isn't important. The word is versatile and can be used in a variety of contexts, from casual conversations to more formal situations. It is essentially the indefinite form of 誰 (だれ), which means "who."
