Vocabulary, one of the three elements in language, is of great importance in the whole system of language.
Words are the basic building blocks of language, the units of meaning from which larger structures such as
sentences, paragraphs and whole texts are formed. It is often said, “Without grammar, little can be conveyed;
without words nothing can be conveyed.” With regard to second language acquisition, vocabulary is an
indispensable and basic part. Both teachers and learners spend lots of time and energy on vocabulary acquisition.
From the millions of vocabulary textbooks in the libraries and bookstores, we can have a brief idea that how much
importance we attach to vocabulary.
