Questions & Answers about natu no yoru ha suzusii desu.
Why is the particle の used between 夏 and 夜?
The particle の links two nouns to express a relationship like possession or description. In 夏の夜, の turns “summer” into an attribute of “night,” giving you “summer nights” (literally “nights of summer”).
Why do we use は after 夜 instead of が?
は marks the topic of the sentence and signals that you’re making a general statement about 夏の夜. If you used が (夏の夜が涼しいです), it would treat “summer nights” as new or surprising information rather than a topic you want to talk about.
What part of speech is すずしい?
すずしい is an い-adjective. い-adjectives can directly modify nouns (e.g. 冷たい水 “cold water”) and, when used predicatively, end in 〜い. For politeness, you add です after them.
Why is there a です at the end of the sentence?
です is the polite copula in Japanese. While you can say the plain form 夏の夜は涼しい in casual speech, adding です (夏の夜は涼しいです) makes the sentence polite.
Why is すずしい written in hiragana instead of the kanji 涼しい?
Beginners’ materials often use hiragana to ease reading. The correct kanji is 涼しい, but writing it as すずしい removes the need to remember that character until you’re ready.
Where is the subject of the sentence?
Japanese frequently omits the explicit subject when context makes it clear. Here, the topic 夏の夜 doubles as the understood subject, so there’s no separate word for “they” or “it.”
How does the word order work in this sentence?
Japanese follows a Topic → (optional) Object → Predicate order.
- Topic: 夏の夜は
- Predicate: 涼しいです
Modifiers (like 夏の modifying 夜) always come before the noun they describe.
