"How to say '一会儿' in English?"
In English, "一会儿" can be translated as "a while" or "sometime." However, the specific translation can vary depending on the context in which it is used. For instance, if you want to tell someone that you will meet them after a short period, you could say "I'll meet you in a while." On the other hand, if you want to refer to an unspecified amount of time in the future, you could use "sometime."
It's worth noting that this phrase is often used in informal Chinese conversations and may not be commonly used in formal English contexts. In such situations, other translations like "in a bit," "after a bit," or "in a little while" might be more appropriate.
