【正确答案】Linguists call all the words in English, i.e. the whole English vocabulary, "English lexis or lexicon". A British linguist named D. Wilkins once said, "Without grammar, people could express few things while without words, people could not express anything." Learning English words is an important part of learning English. There are such a vast number of English words that it is impossible for one to memorize all of them in one's lifetime. In fact, a person's vocabulary is always limited. According to a lexicographer's statistics, Shakespeare mastered about 24,000 words, Milton mastered 16,000 words or so. For more than 2 million words in English, these are very small numbers.
