IELTSAcademic
noun

A very large amount of something, often more than is needed or wanted. It suggests an overwhelming quantity that can feel like too much.

Adinary Nuance

"Plethora" sits closest to "abundance" and "surplus," but it carries a subtle undertone of excess — hinting that there is more than is comfortable or needed. "Abundance" is almost always positive ("an abundance of talent"), while "plethora" can quietly suggest things are overwhelming. "Surplus" is more factual and technical, preferred in economics. In academic and IELTS writing, "plethora" sounds sophisticated and is widely used, but choose "abundance" whenever your meaning is clearly and warmly positive.
