Without grammar you can say little, without lexis you can say nothing. Vocabulary, chunks, patterns, phrases, collocations, words, words with grammar – whatever you want to call it, lexis is the true building blocks of language. What is lexis? What lexis should we teach? At what level? For what course? How much? And how to teach it? How do students best learn it? How does it help with skills? How can we test it?
