Which term is used to describe someone or something that is extremely abundant?

The term that describes someone or something that is extremely abundant is "profuse." This word conveys a sense of overflowing or excessive quantity, often used when referring to things like profuse apologies, profuse vegetation, or profuse offerings, indicating an abundance. It captures the idea of being plentiful and generous to the extent that it becomes noticeable or overwhelming.

The other terms listed refer to different meanings: a pugilist refers to a boxer or someone skilled in fighting, while "prostate" relates to a gland in the male reproductive system and is not concerned with abundance. "Precocious" describes someone, often a child, who is advanced in development or abilities compared to peers, but does not imply abundance in a general sense. Thus, "profuse" is the only term fitting the context of extreme abundance.
