Grammar Patterns
How to Use It
Usage Notes
Use 'atsusa' for weather and climate. It is a neutral noun suitable for both formal and informal registers. Always ensure you use the correct kanji 暑, as 熱 is reserved for physical objects.
Common Mistakes
The most common mistake is using the kanji 熱 (heat of an object) instead of 暑 (heat of weather). Another error is using it to describe the temperature of food, which is incorrect.
Tips
Use with 'kibishii' for emphasis
Adding 'kibishii' (severe) before 'atsusa' highlights how intense the heat is. This is a very common natural collocation in Japanese.
Do not confuse with 'atsusa' (heat of objects)
The kanji 暑 is specifically for weather. Using 熱 for weather is a common writing error.
Japanese summer and heat
Japanese summers are famously humid. The term 'atsusa' often carries a nuance of sticky, oppressive humidity.
Word Origin
Derived from the adjective 'atsui' (hot). The suffix 'sa' turns adjectives into nouns representing the degree of that quality.
Cultural Context
In Japan, the heat of summer is often discussed with concern for health. 'Atsusa-mimai' is a traditional postcard sent during the peak of summer to check on someone's well-being.
Memory Tip
Think of the kanji 暑: the top part is 'sun' (日), and the bottom part is 'person' (者). A person under the sun feels the heat!
