Conventional Figurative Language Theory and idiom motivation

Abstract The central point of discussion is how idiom motivation is reflected in the Conventional Figurative Language Theory. Most lexical units are motivated to a certain extent, i.e. they point to their actual meaning via the meanings of their parts, either parts of their structure or of their conceptual basis. Several types of motivation can be distinguished in the field of phraseology. Apart from the quite small number of idioms where no comprehensible link can be found between the literal reading and the figurative meaning that would allow for a meaningful interpretation of a given expression, all other idioms have to be considered transparent or motivated. Idioms form a very heterogeneous domain in terms of motivation. There are levels of motivation and semantic predictability both from the perspective of a speaker and from the perspective of the semantic structure of a given unit. In this paper, we present a typology of motivation that captures all types of transparent idioms. The typology of idiom motivation connects our theory to the Cognitive Theory of Metaphor and to the Construction Grammar approaches.
