What is the opposite meaning of content?

Opposite meaning of content depends on which pronunciation and meaning you use, as word has two distinct meanings. As adjective pronounced con-TENT meaning satisfied, at peace, and fulfilled, opposite meaning is discontent, dissatisfied, unhappy, restless, unfulfilled, and always wanting more, describing state of lack and envy rather than peace. For example, content person feels enough and grateful, opposite discontent person feels lack and complains, craving more. Other opposites include miserable, anxious, and greedy. As noun pronounced CON-tent meaning material or substance contained inside something like contents of box or digital content like blogs and videos, opposite meaning would be emptiness, void, or container itself rather than what is inside, for example empty box has no contents, or lack of substance. For instance, content of room with HEPA filtration is clean air and equipment, opposite would be empty room with no content. So opposite meaning varies, for emotional contentment opposite is discontentment and dissatisfaction, for material content opposite is emptiness and lack of substance. Understanding opposite requires knowing which meaning intended, as content as satisfied has opposite discontent, while content as material has opposite emptiness, both reflecting absence of what defines content, whether peace or substance.
