“Exploring the Relationship Between Formulaic Language and the Lexicon: A Lexicogrammatical Perspective”

The interaction between vocabulary and grammar has been examined from different linguistic angles. Halliday’s view of lexis and grammar is that they are “complementary perspectives” (1991: 32), that both are notional ends of a lexicogrammatical continuum. He argues that “if you interrogate the system grammatically you will get grammar-like answers and if you interrogate it lexically you get lexis-like answers” (1992: 64). Our approach in this course has consisted in interrogating language from the viewpoint of “lexis”, “the lexicon” (or “mental lexicon).
Question: How do you think formulaic language (phraseology) should be more rightly approached?
