Which word can imply the idea of regularity or normalcy in daily activities?

The word "quotidian" is derived from the Latin "quotidianus," meaning "daily." It directly refers to something that occurs every day or is characteristic of the everyday routine. In this context, it perfectly embodies the concept of regularity or normalcy in daily activities, as it emphasizes the ordinary nature of these occurrences.

While "logistical" pertains to the organization and management of complex operations, it does not convey the idea of regularity in daily activities. "Prosaic" describes something that is dull or lacking in imagination, often used to highlight the mundane aspects of life—though it can relate to everyday experiences, it leans more toward an absence of excitement rather than regularity. "Commonplace" refers to something that is ordinary or unremarkable, which could suggest familiarity but does not specifically indicate a routine structure as "quotidian" does.
