Lexical Approach

The Lexical Approach was proposed by Michael Lewis in The Lexical Approach (1993) and further developed in Implementing the Lexical Approach (1997). Its central claim inverts the traditional grammar-vocabulary hierarchy: "Language consists of grammaticalised lexis, not lexicalised grammar."

Core Argument

Lewis argues that fluent language production is not primarily a syntactic rule-governed process but the retrieval of larger phrasal units from memory. Grammar emerges from patterns learners notice within these units rather than being taught as an abstract system first. This aligns with corpus linguistics findings that much of natural language is semi-fixed and formulaic.

Types of Lexical Units

Lewis identifies several categories beyond the single word:

• Polywords -- Fixed multi-word items (e.g., by the way, on the other hand)
• Collocations -- Frequently co-occurring word combinations, both fixed (make a decision) and freer (heavy rain)
• Institutionalised expressions -- Pragmatic chunks used in social interaction (I see what you mean, if I were you)
• Sentence frames -- Semi-fixed patterns with open slots (the thing is..., it's worth + -ing)

Pedagogical Implications

The Lexical Approach asks teachers to raise learner awareness of chunks rather than drilling grammar rules. Key classroom techniques include noticing activities with authentic texts, Collocation matching, and keeping lexical notebooks organised by chunk type rather than single-word entries.

Criticisms

The approach has been criticised for lacking a clear methodology -- Lewis describes what language is more than how to teach it. It also underspecifies how beginners with small lexicons can engage meaningfully with chunk-based learning.
