Meaning and Usage
The verb 流す (ながす) primarily means "to let something flow or run." It is commonly used for liquids like water or blood, but also for abstract things like tears or music.
Common Contexts
- Literal flow: letting water or other liquids flow somewhere, e.g., 川に水を流す (to let water flow into the river).
- Shedding: used with tears or blood, e.g., 涙を流す (to shed tears).
- Playing or broadcasting: used when playing music or sounds, e.g., 音楽を流す (to play music).
Collocations and Patterns
- 涙を流す: to cry or shed tears, often expressing sadness or emotion.
- 音楽を流す: to play music, common in casual and formal settings.
- 水を流す: to let water flow, often in physical or environmental contexts.
Nuances and Tips
When using 流す, consider whether the flow is physical (water, blood) or metaphorical (music, tears). It is a versatile verb but usually implies an intentional or controlled action. Avoid confusing 流す with 流れる, which means "to flow" but is intransitive (the subject flows by itself). 流す is transitive and requires an object that is being caused to flow.
