What is the best antonym for the word restive?

The best antonym for the word "restive" is "calm." The term "restive" refers to a state of being restless or unable to stay still, often resulting from anxiety or impatience. When something or someone is restive, they exhibit a form of agitation or discomfort. On the other hand, "calm" signifies a state of peacefulness and tranquility, marking a clear contrast to the restlessness implied by "restive."

This relationship highlights the fundamental difference in their meanings, where calmness represents stability and composed behavior, while restiveness denotes a lack of such peace. Other options, such as "nervous," might suggest some level of anxiety but do not provide the direct antonym that "calm" does, focusing instead on emotional states that are still somewhat related to restlessness.
