Questions & Answers about kono eiga ha omosirokunai desu.
What does この mean in this sentence?
この is a demonstrative adjective meaning “this.” It comes directly before the noun 映画 to specify “this movie.”
Why is the particle は used after 映画 instead of が?
は marks the topic (“As for this movie…”). It sets up what you’re talking about. が would mark the subject or emphasize it, but here you’re simply stating your opinion about the topic.
How do you form the negative of the i-adjective 面白い?
- Drop the final い from 面白い.
- Add くない to get the plain negative: 面白くない.
- To make it polite, append です: 面白くないです.
Why is there a です at the end if the adjective is already negative?
です is the polite copula. It doesn’t change the negative meaning; it simply makes the whole sentence polite, much like adding “is” in English courtesy formulas.
What’s a more formal way to say “not interesting” instead of 面白くないです?
You can use the adjective stem plus the polite negative copula ありません:
面白くありません
This is more formal and can sound more business-like.
How would you say the sentence in casual (plain) speech?
Drop the polite です entirely:
この映画は面白くない。
Why are there spaces between words in the example?
Japanese is normally written without spaces. Here, spaces separate elements (この｜映画｜は｜面白くない｜です) to help learners see each word or particle clearly.
