What is the difference between a cryptocurrency and a token?

Could you please elaborate on the distinction between a cryptocurrency and a token? I understand they both play a role in the digital economy, but I'm curious about the specific differences in their nature, functions, and applications. Is it related to their underlying technology, the way they are traded, or perhaps their regulatory status? I'd appreciate it if you could provide a clear and concise explanation to help me grasp the nuances between the two.
