How is the word 'meager' best described?

The word 'meager' is best described as insufficient in quantity or quality, which aligns perfectly with the essence of the term. It conveys a sense of scarcity, lack, or deficiency, often used to describe something that is not enough to meet a need or expectation. When referring to resources, a 'meager' supply signifies that there is a shortfall compared to what might typically be considered adequate or satisfactory. This connotation of inadequacy is central to the meaning of 'meager,' thereby making the description of being insufficient the most accurate choice.

The other descriptions do not capture the true nature of 'meager.' Terms implying richness, abundance, or strength contradict the essence of the word, as 'meager' specifically relates to a lack thereof. Similarly, a moderate size does not imply a lack; it could indicate a balanced or adequate amount, which diverges from the intended meaning of 'meager.' Thus, the best representation of the word is indeed insufficient in quantity or quality.
