I will give you an example of their words. They told me chou signifies a book: so that I thought whenever the word chou was pronounced, a book was the subject. Not at all! Chou, the next time I heard it, I found signified a tree. Now I was to recollect, chou was a book, or a tree. But this amounted to nothing; chou, I found, expressed also great heats; chou is to relate; chou is the Aurora; chou means to be accustomed; chou expresses the loss of a wager, &c. I should not finish, were I to attempt to give you all its significations.
