Usage of 来回
The word 来回 (láihuí) primarily means "back and forth" or "round trip." It is often used to describe movement between two points repeatedly or the act of going and returning.
Common contexts
- Physical movement: Describing traveling back and forth, such as commuting or searching.
- Checking or confirming: Used metaphorically to mean reviewing or double-checking information.
Collocations and patterns
- 来回走 (láihuí zǒu): to walk back and forth, often implying searching or pacing.
- 来回确认 (láihuí quèrèn): to double-check or confirm repeatedly.
- 来回时间 (láihuí shíjiān): round-trip time, used in travel contexts.
Nuances
When using 来回 to describe movement, it emphasizes the repeated or reciprocal nature of the action. It is more specific than simply saying "go" or "come" because it implies a return journey or repeated trips.
Avoid confusing 来回 with 单程 (dānchéng), which means one-way. 来回 always implies a two-way or repeated action.
Register
来回 is neutral and commonly used in both spoken and written Mandarin, suitable for daily conversation and formal contexts.
