The Chinese word 每日 (měi rì), meaning "every day" or "daily", is formed through a straightforward and common compounding process in Mandarin. It combines the character 每 (měi), which functions as a universal quantifier meaning "each" or "every", with the character 日 (rì), the core noun meaning "day". The structure follows a standard modifier-noun pattern, where 每 modifies and quantifies 日, creating a semantic unit that specifies a recurring daily occurrence. This type of formation is highly productive in Chinese, similar to words like 每年 (měi nián, every year) or 每人 (měi rén, every person).
