Which word is synonymous with laziness?

The word "slothful" directly describes a state of laziness or idleness, making it synonymous with the concept of lacking energy or being unwilling to exert effort. This term derives from "sloth," which is often associated with lazing around or avoiding work. It effectively conveys the idea of a slow-moving or inactive disposition.

While "indolent" is also synonymous with laziness, the context or nuance of the question elevates "slothful" as the primary term for laziness. The other options, "energetic" and "active," are antonyms of laziness, representing enthusiasm and vigor, and are therefore not relevant in this context. The use of "slothful" captures the essence of laziness accurately, allowing for a clear understanding of the term.
