Which term refers to a limited or insufficient amount?

The term that refers to a limited or insufficient amount is "paucity." This word specifically denotes a scarcity or inadequacy in quantity, suggesting that something is lacking or not sufficiently present. It emphasizes the idea of a deficiency or smallness, particularly when discussing resources, opportunities, or data.

While "meager" also describes something as insufficient or poor in quality or quantity, it typically has a more qualitative connotation, often implying that what is provided is not only limited but also of inferior quality. "Mediocrity" deals more with the state of being average or ordinary, rather than a lack or limitation. "Stoic" pertains to a philosophy regarding the endurance of pain or hardship without complaint, rather than addressing the concept of scarcity. Thus, "paucity" aligns most directly with the idea of having a limited or insufficient amount.
