The antonym for continuous tremors is stillness. When there is stillness, there is complete absence of movement or trembling. Instead of persistent quaking, the opposite implies a state of quietness or calmness. For instance, in a calm sea, there are no continuous tremors, and the water is still as there are no visible movements. A similar case can be seen in the human body, where the opposite of continuous tremors is stability, such as in a person who is not trembling, shaking, or experiencing spasms. Therefore, the antonyms of continuous tremors are stillness, stability, and calmness, among others.
