I’m reading a book about web design now. There are a lot of words unfamiliar to me; I must look many words up. The words are totally different from everyday conversation words. I think I don’t need to use these words, but I must be able to understand and read them.
No one can understand one word perfectly, even in their native tongue. In order to not stop reading the book, I should decrease the number of times I keep looking up unfamiliar words.
