Four hundred Greek idiomatic expressions: Ratings for subjective frequency, ambiguity, and decomposability

Idioms differ from other forms of figurative language because of their dimensions of subjective frequency, ambiguity (possibility of having a literal interpretation), and decomposability (possibility of the idiom’s words to assist in its figurative interpretation). This study focuses on the Greek language and aims at providing the first corpus of 400 Greek idioms rated for their dimensions by 113 native Greek students, aged 19 to 39 years. The study aimed at (1) rating all idioms for their degree of subjective frequency, ambiguity, and decomposability, and (2) investigating the relationships between these dimensions. Three different assessments were conducted, during which the participants were asked to evaluate the degree of idioms’ subjective frequency, ambiguity, and decomposability. The idioms were selected from a dictionary of Greek idioms titled “Dictionary of Idioms in Modern Greek” (Vlaxopoulos, 2007). This study resulted in the first database of Greek idioms assessed for their dimensions. The intraclass correlation coefficient (ICC) (two-way mixed, absolute agreement) demonstrated high internal consistency in the ratings given for each dimension, for the same idiom, by the different individual raters. Correlational analyses showed that subjective frequency was positively moderately correlated with decomposability, and positively weakly correlated with ambiguity, while decomposability was positively moderately correlated with ambiguity.
