Is The Wealth of Nations right for your level?
To recognise 95% of the running words in The Wealth of Nations, you need its 3,061 most frequent word forms; for 98%, the share at which most readers manage a novel without a dictionary, 5,683. The median English C1 book in our table needs 4,633 forms for 95%, so by this measure the book is easier than most for its level: number 4 of 11, easiest first.
A word form is any spelling that appears in the text, so “walk” and “walked” count twice, and names count too. These numbers are a guide to how much vocabulary the book asks for, not a test. The level itself was set by hand by our team. Before you commit, read one page of the free edition and count the words you do not know: the one-page test takes two minutes.
Which words should you know before you start?
These are the words that The Wealth of Nations uses most often but that are not among the 2,000 most common word forms across all 309 English books in our library; the number is how many times each appears. Names of people and places are left out. Learning a handful of them first makes the opening chapters easier.
