Questions & Answers about tā jīntiān zǒucuòlù le, suǒyǐ lái de hěn wǎn.
What does 了 do in 走错路了? Is it past tense?
了 here is the perfective aspect marker. It shows that the action taking the wrong road is viewed as a completed event.
It often corresponds to past events in English, but it is not a true past-tense marker; it just marks a bounded, finished action.
Without 了, 他今天走错路 could sound more like a general statement or might feel incomplete in this context, because the lateness is clearly caused by a specific finished event.
Why is 走错路 written as three characters? What exactly does 错 do?
走错路 is a verb–result–object structure:
- 走 – to walk / to go (by walking)
- 错 – wrong; here it’s a result complement (showing the result of the action)
- 路 – road / way
So literally it is “walk–wrong–road” → to take the wrong road / go the wrong way.
错 tells you how the action turned out (wrongly).
Could we say 他今天走错了路 or 他今天走错了 instead? What’s the difference from 他今天走错路了?
