从…起【cóng … qǐ】

从 + time + 起 means "from … on, starting from". It marks the moment something begins and says it continues after that. It is a little formal, common in notices, rules and announcements.

The time phrase comes before the verb – at the start of the sentence or right after the subject.

从…开始 means the same and is more spoken. 自…起 is the most formal, and turns up in legal texts and official notices.

Word order

English often puts "from next week" at the end. The Chinese time phrase can't follow the verb.

• × 我们放假从明天起 → 从明天起，我们放假
• × 他开始工作从九月起 → 他从九月起开始工作

从 + place + 起 also exists, as in 从这里起 "from here on", but most uses name a time.
