How do word roots contribute to the understanding of idiomatic expressions?

Word roots contribute to the understanding of idiomatic expressions by providing insight into the origins and meanings of the individual words within the expression. Idiomatic expressions often contain words that have evolved from their original roots, and understanding these roots can help decipher the figurative or metaphorical meanings of the expression. By breaking down the words into their root forms, one can identify any literal meanings or associations that may contribute to the overall understanding of the idiomatic expression. Additionally, knowledge of word roots can aid in recognizing patterns or connections between different idiomatic expressions that share similar roots, further enhancing comprehension and interpretation.
