Traditional phraseological perspective focuses on syntactic and semantic aspects of chunks and its most important criteria of chunk identifications and classifications are compositionality and frozenness/fixedness. Psycholinguistic perspective focuses on the psychological salience of chunks and its most important criterion of identifying a chunk is whether it is processed as a whole unit. Corpus linguistic perspective focuses on frequencies of chunks and its identification of chunks is done on the basis of frequency counts. All of the three perspectives have tapped into the phenomenon of multi-word combinations and yielded fruitful findings on the use of chunks in aspects of quantitative, syntactic, semantic, functional, and psychological features; however, each has their pros and cons展开更多
