Widening my range of vocabulary In my opinion, a high level of vocabulary is key for mastering a foreign language. Therefore, I spent my entire afternoon with learning vocabulary and writing new vocabulary cards for my extensive archive of more than 3.000 handwritten cards. Every card has one new word written on it as well as a sentence that is built with this word, to show how it's used actually. Some of the cards also contain idioms and proverbs - both an essential part to speak a foreign language more naturally.
