KEY POINTS • To learn vocabulary efficiently, begin by learning the top thousand words in your target language. • If you’re aiming for a high degree of fluency, then keep going until you know the top fifteen hundred to two thousand words. • Once you’re done building a foundation, choose additional words based upon your individual needs. You can find these words by skimming through a thematic vocabulary book and finding key words for every context you need—travel, music, business, and so on.
