Hello Somin,

When looking at our site, the words with a green check are what we call ¡°learnable.¡± For these words, we have written a descriptive definition and have prepared sufficient questions to thoroughly test knowledge of the word in multiple senses. "Sea of Japan" is not currently learnable or searchable on our site, but I will share your suggestion with our content team.

To view our help center article on learnable words, follow the link below:
