Definition

1. Adverb:
   • Very clearly, distinctly, in great detail: "mồn một" describes seeing or hearing something with extreme clarity, leaving no room for doubt or missing any details. It emphasizes the completeness and sharpness of perception.

Usage Examples

• Adverb:
  • Tôi nghe rõ mồn một câu chuyện họ bàn tán. (I heard their gossiping conversation very distinctly.)
  • Qua kính hiển vi, chúng ta có thể thấy rõ mồn một tế bào. (Through a microscope, we can see the cell in great detail.)
  • Anh ấy kể lại sự việc rõ mồn một cho cảnh sát. (He recounted the incident to the police with perfect clarity.)

Advanced Usage

• "Rõ mồn một": This is the most common and fixed collocation. "Rõ" (clear) intensifies "mồn một". It functions as an adverbial phrase meaning "crystal clear" or "in minute detail".
  • Mọi chi tiết trong hợp đồng đều được ghi rõ mồn một. (Every detail in the contract is recorded with crystal clarity.)
• Used to emphasize that something is perceived not just clearly, but with all its fine points and specifics visible or audible.

Variants and Related Words

• Rõ ràng (adj/adv): clear, clearly. (A more common and general synonym, but lacks the emphatic, detailed nuance of "mồn một").
• Tường tận (adj): thorough, detailed. (Often used for knowledge or description, e.g., "hiểu tường tận" - to understand thoroughly).
• Chi tiết (adj/n): detailed, detail. (Focuses on the presence of many small parts rather than the clarity of perception).

Synonyms

• Rõ ràng từng chi tiết: clearly, in every detail.
• Một cách tường tận: in a thorough manner.
• Rành rành (adv): clearly, unmistakably (often for something evident).

Notes on Usage

• Register: "Mồn một" is colloquial and vivid. It is common in spoken Vietnamese and informal writing but less likely in very formal documents.
• Fixed Phrase: It is almost exclusively used in the pattern "rõ mồn một". Using "mồn một" alone is very rare and might sound incomplete.
• Senses: While the core meaning relates to clarity of perception (sight, hearing), it can be extended metaphorically to mean understanding something completely and without ambiguity.
  • Tôi hiểu rõ mồn một ý anh rồi. (I understand your meaning perfectly clearly now.)
