Character Breakdown

Meaning and Usage

The verb 蒸す (むす) primarily means "to steam" food, a common cooking method in Japanese cuisine. It can also describe the weather being hot and humid or sultry, often used to express discomfort due to moisture and heat.

  • 蒸す料理 (むすりょうり): steamed dishes, emphasizing the cooking method.
  • 蒸し暑い (むしあつい): sultry, hot and humid weather, a common seasonal expression.
  • 蒸しタオル (むしたおる): steamed towel, often used in skincare or health contexts.

Usage Notes

When using 蒸す to describe cooking, it often involves vegetables, fish, or buns. The weather-related use is more colloquial and often paired with adjectives like 暑い (hot) to form 蒸し暑い. Learners should not confuse 蒸す with 煮る (にる, to boil/simmer) or 焼く (やく, to grill/bake).

蒸す is neutral and common in both spoken and written Japanese. It is appropriate in casual and formal contexts when discussing cooking or weather.
