Which word refers to something that has the quality of producing sound?

The term "sonorous" is used to describe something that produces a deep, resonant sound. It typically refers to sounds that are rich, full, and capable of filling space, often associated with musical instruments, voices, or specific acoustic properties of materials.

When relying on the root "son," which relates to sound, "sonorous" encapsulates the essence of producing sound effectively. It is often used in contexts where the quality, depth, or richness of a sound is emphasized, making it the best fit for describing something that is characterized by its ability to generate sound.

In contrast, the other options refer to unrelated qualities. For example, "somnolent" means sleep-inducing or drowsy, "stave" relates to the wooden slats forming the sides of a barrel or to breaking something, and "teetotal" refers to abstaining from alcohol. None of these terms align with the quality of producing sound, thus reinforcing "sonorous" as the best choice.
