FEATURES OF SEMANTIC COMPOSITIONALITY OF IDIOMS WITH THE COMPONENT "PHENOMENON OF NATURE"
The article describes features of semantic compositionality of phraseological unities with the component “natural phenomenon”. Idioms are treated as complex signs consisting of several components. By studying semantic potency of base component of idioms, the authors analyze semantic aspects of its compatibility with the other components of an idiom. A number of semantic models of metaphorization have been identified to prove the existence of systemic phraseological meanings within idiomatic units.
