-Japanese interrogative sentences are typically formed using interrogative words (like なんで, なぜ, どうして) and sentence-final interrogative particles (like の, か). Looking at Ms. Nagasaki Soyo's famous quote "なんで春日影やったの" (Why play Kasukage?), we can identify its structural components:

 In this way, TypeScript's type system can not only represent the structure of Japanese interrogative sentences but also validate the grammatical correctness of sentences at compile time. This demonstrates how the type system can help us learn and master Japanese grammar rules.
