The word "copulae" refers to a type of verb that links the subject of a sentence to a predicate. The antonyms for copulae would be action verbs, which show physical or mental activity. Some examples of action verbs are run, eat, read, write, dance, sing, and think. Unlike copulae, action verbs express a sense of movement and change, making the sentence more dynamic and engaging. By using action verbs instead of copulae, writers can create vivid descriptions and convey a sense of urgency, excitement, or drama in their prose.
