The term 'de compounds' refers to words that have been formed by adding the prefix 'de-' to a base word, changing its meaning to the opposite or removal of the original word. The antonyms for de compounds would be words that convey the opposite meaning of the de-derived words. For instance, the antonym of 'dethrone' would be 'enthronement,' the antonym of 'defrost' would be 'freeze,' the antonym of 'deactivate' would be 'activate,' and so on. These opposites can be used in writing to provide a more nuanced and varied meaning to the text, or they can be used to play word games or quizzes with friends and family.
