The meaning of the term lexis is a stock of words in a language. It is also called lexical resource which refers to the range of vocabulary that you should use while speaking in English. As the IELTS is primarily an English proficiency test, you need to prove that you have the ability to use a word in the right context. That is why this component lexical resource is very essential.
In the speaking test also, you need to speak fluently and display your ability to use the language without hesitation. The topic is a very common one. But, you need to speak about it eloquently and demonstrate your language skill. A person with poor communication skills, who cannot extend the sentence and talk will definitely face a problem in the main test. In order to avoid that, you should pay close attention to learning words. Not just learning the words, but you should know when to use it(in the appropriate time) and how to use the words.
Thus, the criteria of lexical resources focuses on the range of vocabulary a candidate uses. Generally the wider the range of vocabulary or expression used correctly and appropriately, the better a candidate will score. Learn about the various aspects of vocabulary listed here.
Make a cup of tea; Make a phone call; Make too much noise; Make changes; Make a mistake; Make a decision Do your homework; Do an experiment; Do research; Do your best
