Which term describes something traditional or mundane?

The term that describes something traditional or mundane is "conventional." This word relates to established norms, customs, or practices that are widely accepted and generally followed within a society or particular context. When something is labeled as conventional, it suggests a sense of regularity and predictability, aligning with what is considered standard or typical behavior.

In contrast, "innovative," "unconventional," and "radical" connote ideas or actions that break away from traditional norms. "Innovative" implies creativity and newness, focusing on novel ideas or approaches. "Unconventional" refers to methods or beliefs that diverge from what is widely accepted. Lastly, "radical" highlights extreme changes or actions that fundamentally alter existing systems or beliefs. Thus, these terms are distinct from the traditional qualities described by "conventional," making it the most fitting choice for this question.
