thiên xạ
Definition
- Noun:
- Emanation: The act or process of something immaterial (such as light, heat, an idea, or a quality) flowing out or originating from a source. This is a formal, often philosophical or scientific term.
Usage Examples
- Noun:
- Ánh sáng là một thiên xạ từ mặt trời. (Light is an emanation from the sun.)
- Theo một số học thuyết, vũ trụ là thiên xạ từ một nguồn duy nhất. (According to some doctrines, the universe is an emanation from a single source.)
Advanced Usage
- The word "thiên xạ" is highly specialized and literary. In modern Vietnamese, more common synonyms like "sự tỏa ra" (the act of radiating) or "sự phát ra" (the act of emitting) are typically used in everyday or scientific contexts.
Word Origin
- Thiên xạ is a Sino-Vietnamese word (Hán Việt). "Thiên" (天) can mean "heaven" or "natural," and "xạ" (射) means "to shoot" or "to project." The compound thus carries the sense of "a natural projection" or "something radiated forth."
Synonyms
- Emanation: Something that originates or flows from a source.
- Emission: The act of sending out (e.g., light, heat, gas).
- Radiation: The process of emitting energy as waves or particles.
Note on Usage
- "Thiên xạ" is an archaic and very rare term in contemporary Vietnamese. You will almost never encounter it in spoken language or modern writing. Its primary use today is in the translation of specialized philosophical or religious texts. The reference definition from the Vietnamese-French dictionary confirms its meaning as "émanation" but also indicates its status as a rarely used, literary word.
