2. Literature review

2.1 Idiom

2.1.1 The Concept of idiom

The most widely recognized features of an idiom appear to be its multiwordedness and ambiguity in meaning, according to Summers (1998), idiom is “a phrase which means something different from the meaning of the separate words from which it is formed.” whereas Cooper (1999) defines it “an expression whose meaning cannot always be readily derived from the usual meaning of its constituent elements. Also, Strassler’s definition (1982) is once widely accepted that idiom is “a concatenation of more than one lexeme whose meaning is not derived from the meanings of its constituents and which does not consist of a verb plus an adverbial particle or preposition.”

These two features are more succinctly expressed as compositeness and semantic opacity by Fernado (1996), who adds one more feature: institutionalization, i.e., conventionalization of expressions which are initially ad-hoc, and in this sense novel, in meaning.
