Is a bond a derivative?

Could you please clarify for me? I'm a bit confused about the financial instruments. Is a bond considered a derivative, or does it fall into a different category? I've heard conflicting opinions on this matter, and I'm trying to understand the distinction better. Could you explain the characteristics of a bond and how they differ from derivatives, if at all? It would be greatly appreciated if you could provide a concise yet comprehensive answer. Thank you in advance for your assistance.
