Is anyone familiar with the book "Fluent Forever" by Gabriel Wyner? While I have not read it, I have read alot about it on the website. The vocabulary section of the website is particularly interesting. He basically says (and backs it up with some research) that by knowing the 1000 most commonly used words in a language, one could understand roughly 70% of the language. By knowing the 2000 most common words, understanding would increase to 80%. He has created a list of the 625 most commonly used words in English, which he says will correspond to the 1000 most common in other languages. How he came up with 625 I do not know. I will add that verbs in the word list only include the infinitives, and he assumes that you will learn the conjugations in the most commonly used tenses. Needless to say, I have decided to try this out. I am slowly creating a deck in Anki of these 625 words for my Spanish learning. I am drilling from this deck daily (or almost daily). We will see how it goes. Any thoughts?
