What word represents a state of inactivity or calmness?

The word "quiescence" refers to a state of inactivity, rest, or calmness. It is often used to describe a period during which there is little to no movement, action, or activity. In various contexts, quiescence can imply tranquility or a temporary pause in action, making it an appropriate choice for the question at hand.

The other words do not encapsulate this idea of calm inactivity. "Fatuous" refers to a foolish or silly quality, "virago" denotes a strong or fierce woman, often with a connotation of a scolding or aggressive nature, and "wend" means to proceed or go in a particular direction, which indicates movement rather than stillness. Therefore, "quiescence" is the most fitting term to describe a state of inactivity or calmness.
