Questions & Answers about sakana wa shinsen desu.
What does the particle は do in this sentence?
The particle は marks the topic of the sentence. It tells the listener that “fish” (魚) is what we’re talking about. It doesn’t emphasize the subject like が does but rather sets the context: “As for fish, …”
Why isn’t there a particle after 新鮮?
Because 新鮮 is a na-adjective (形容動詞). When linking a na-adjective directly to the copula です, you drop the な that would appear if you were modifying a noun. So you simply write 新鮮 + です.
What type of adjective is 新鮮, and how does its grammar differ from an i-adjective?
新鮮 (しんせん) is a na-adjective.
- To modify a noun: add な, e.g. 新鮮な魚 (“fresh fish”).
- To make predicative statements: attach です or conjugate です directly, without な, e.g. 魚は新鮮です.
In contrast, i-adjectives (like 高い, “expensive”) attach directly to nouns (高い車) and conjugate themselves (高くない, 高かった).
What exactly is です in this context?
です is the polite copula, roughly equivalent to English “is”/“are.” It links the topic or subject (here marked by ) to the adjective . There’s no separate “to be” verb in Japanese; fulfills that role politely.
