Productions are expressive works of art, music, or literature created for an audience. The opposite of productions are non-productions or simply non-creative works. These can be everyday objects or routine activities that lack imagination. Another antonym for productions could be "destructions," referring to acts of ruining or demolishing things. Alternatively, "derivative" may represent a different antonym for productions, suggesting that a work lacks originality or is heavily influenced by previous works. Finally, "decline" could be an antonym for productions, indicating a decrease in the quality of artwork or cultural expression over time.
