Idiomatic expressions are conventionalized multiword units whose meanings cannot always be fully derived from the literal meanings of their individual components or from the grammatical rules governing their combination ^[1][2]. They vary in semantic transparency, syntactic flexibility, and lexical fixedness, ranging from relatively transparent expressions to highly non-compositional phrases whose interpretations depend on established linguistic conventions ^[1][2]. Idiomatic expressions are examined in relation to phraseology, lexical semantics, and the conventionalized patterns through which speakers encode and interpret meaning in a language.
