What is the term for a state of quiet and inactive restfulness?

The term "quiescence" refers to a state of quietness or inactivity, signifying a kind of restful calm. It evokes a sense of tranquility and being at peace, often without any disturbance or agitation. This word is particularly apt in contexts where one describes a serene environment or a period of hiatus, where action or motion is suspended. The root of the word suggests a natural pause in activity, making it synonymous with rest and stillness.

In contrast, the other options present different meanings. "Fatuous" describes something that is foolish or silly, lacking in intelligence or awareness. "Tumid" means swollen or inflated and is often used to describe something that is physically enlarged or overly complex in language or expression. "Virago" refers to a strong, assertive woman, sometimes with a connotation of being overbearing or aggressive. Each of these words conveys distinct ideas that do not align with the notion of restful quietude encapsulated by "quiescence."
