WHAT IS VOCABULARY

1.1.1. What is vocabulary?

According to The Longman Dictionary of Language Teaching and Applied Linguistics,

vocabulary is defined as “a set of lexemes, including single words, compound words and

idioms”. Otherwise, in the Oxford Advanced learner’s Dictionary, vocabulary is defined quite

simple as “all the words that a person knows or uses.”

In Stahl’s view, vocabulary is the knowledge of words and word meanings then he offered

a clear and specific definition of vocabulary by saying that “vocabulary knowledge is knowledge;

the knowledge of a word not only implies a definition, but also implies how that word fits into

world.” (Stahl, S.A. 2005). The author emphasizes that when learning vocabulary, learners must

acquire the knowledge of words or word meanings and understand how the word they have learnt

can be used appropriately in the real-world situations.
