Out-cries, a noun referring to loud and emotional protests or complaints, can have various antonyms depending on the context in which it is used. Some antonyms for out-cries could include peace, calmness, quietness, approval, and indifference. If one wants to communicate the opposite of a noisy protest or outcry, peace would be an antonym that captures the opposite meaning. Calmness and quietness also introduce the idea of silence and serenity. However, when used in a context that requires a response or attention, antonyms such as approval or indifference would be more appropriate. These words represent a lack of protest, and thereby contrasting the idea of out-cries.
