chapter 2 Idioms and idiomaticity
This chapter introduces idioms and idiom-like features in phrases and collocations. There is no shortage of descriptions and classifications of idiom in the literature (see especially Makkai 1972; Fernando﻿ & Flavell﻿ 1982; Fernando﻿ 1996; Moon﻿ 1998), but most existing work is theoretical in nature and requires testing against the reality of idioms in use. The essential features that must be present in order to define a phrase as an idiom are outlined, and the notion of collocational harmony﻿ is introduced to explain how literal﻿ and non-literal meanings are perceived in text. On the basis of these features, the difference between idiomatic and non-idiomatic collocations is also explained. The chapter ends with a description and discussion of the data selected for inclusion in this study.
