天天

天天 means 'every day' and is used to describe actions or situations that occur regularly on a daily basis. It emphasizes consistency and routine, distinguishing it from less frequent occurrences like 'sometimes' or 'often.'

The word consists of two instances of 天 (tiān), which means 'day.' Repeating the character reinforces the idea of daily occurrence, making it a common expression in both spoken and written Chinese.

天天 is often used in daily conversations to talk about habits, routines, or ongoing conditions. For example, it can be used to express that someone exercises every day or that a situation continues without interruption. It's also commonly used in phrases like 天天开心 (tīan tīan kāixīn), meaning 'to be happy every day.'
