Similar Grammar Points

• 以前 (yǐqián): Also means "before" or "previously." However, 以前 does not focus on completed actions; rather, it contextualizes a time before another event.
• 过 (guò): This is a grammatical aspect marker used to indicate experiences. However, it doesn't have the same emphasis on the "once" aspect as 曾经 does. For example, “我去过北京” focuses on the experience of going to Beijing; “我曾经去过北京” emphasizes that it was a past experience which is not the case now.
