The antonyms for the word "non observances" are "observances" or "compliance." Observance refers to the act of observing or adhering to a particular custom, tradition, or rule. Compliance, on the other hand, means following or obeying rules, laws or customs. Both these antonyms describe a person's willingness to follow the norms and conduct themselves accordingly. Non-observances, therefore, could imply a disregard for the established customs or rules, which could lead to negative consequences. In contrast, observances and compliance can lead to positive outcomes, including social harmony, respect, and recognition.
