Why Vocabulary Matters


Vocabulary is one of the most crucial skills needed for learning a foreign language. It forms the foundation for developing all other skills: reading comprehension, listening comprehension, speaking, writing, spelling, and pronunciation.


When interacting with native Japanese speakers, watching movies without subtitles, listening to your favorite Japanese songs, or reading texts, language learners must operate with words.
