Meaning and Usage
"粉" (こな) primarily means "powder" or "flour." It refers to substances in a fine, dry, particulate form. This word is commonly used in cooking contexts, such as flour for baking, but also in medicine or chemicals where powders are common.
Common Collocations
- 小麦粉 (こむぎこ): wheat flour, used in baking and cooking.
- 粉薬 (こなぐすり): powdered medicine, often prescribed for easier swallowing or faster absorption.
- 粉を溶かす (こなをとかす): to dissolve powder, a common phrase when preparing drinks or medicines.
Usage Notes
When using "粉," it often implies a fine texture and dryness. It is different from "粒" (つぶ), which means "grain" or "granule," indicating larger particles. Learners sometimes confuse "粉" with "粉末" (ふんまつ), which is a more formal or scientific term for powder. "粉" is more common in everyday conversation.
Register and Politeness
"粉" is a neutral noun and can be used in both casual and formal contexts. However, in medical or scientific contexts, "粉末" might be preferred for precision.
Common Mistake
Avoid using "粉" to refer to any small particles indiscriminately; it specifically means powdery substances. For example, sand is not usually called "粉." Instead, use "砂" (すな) for sand.
