What meaning is shared by the adjectives macer and tenuis?

The adjectives "macer" and "tenuis" both convey a sense of thinness or slenderness in various contexts. "Macer," derived from Latin, often describes something that is lean or emaciated, emphasizing a lack of flesh or fat. "Tenuis," also from Latin, translates to thin or finely made, suggesting a lightness or delicacy in structure or substance.

In both cases, the core idea revolves around a lack of mass or substance, highlighting traits associated with being slender or not dense. This shared meaning aligns perfectly with the answer indicating thinness. The other options—thick, fat, and strong—do not relate to the essence of either adjective, which focuses specifically on a lean and delicate quality.
