The word "de-crepitate" means to stop cracking or making a popping sound, but there are several antonyms that are the opposite of this action. One antonym is "pop," which means to make a sharp, explosive noise. Another antonym is "snap," which refers to a sudden break or cracking sound. "Crack" is also an antonym of "de-crepitate" because it means to break or split with a sharp sound. On the other hand, "quiet" is not an antonym of "de-crepitate" since it signifies the absence of sound. Other antonyms of "de-crepitate" include explode, burst, and detonate.
