It is easy to lookup or ask the meaning of the 1-3 words you don't know in a sentence. It is best to always have some percentage of the content not be what you know, otherwise you will plateau. If you are speaking/writing, much easier to form a sentence and search for the one word you don't know than search how to generate an entire sentence structure.
