The phrase "depending on circumstances" is often used to acknowledge that a particular answer or decision can vary based on different situational factors. However, there are various synonyms that can be used to convey a similar message. For instance, "subject to change," "conditional," and "contingent" all indicate that something is reliant on specific circumstances but doesn't necessarily provide the specifics. "Variable," "flexible," and "fluid" suggest that something is adaptable and can shift based on different factors. "Contextual," "situational," and "environmental" all suggest that a decision or action is influenced by the surrounding circumstances. Ultimately, the use of synonyms can help communicate flexibility and adaptability in decision-making.
