The phrase “daily quota” might be more familiar to you than the related adjective “quotidian,” which means either “daily” or “ordinary,” depending on the context. While you could indeed have a quotidian quota, the similar-looking words have different Latin roots. “Quotidian” comes from the Latin “cotidie,” meaning “daily,” and as it developed through Old French and Middle English, the spelling turned from a “c” to a “q.” “Quota,” which means “a fixed share” or “a limited quantity,” comes from the Latin “quot,” meaning “how much.”
