Final answer:
The statement about idioms having a figurative meaning distinct from their literal elements is true. Idioms enhance expression in creative writing and poetry.
Step-by-step explanation:
The statement that an idiom is a series of fixed lexical items that have their own figurative meaning different from their literal component elements is True. Idioms are common in many languages and are often used to express ideas in a more vivid or imaginative way than literal language allows. For example, when someone says they are 'feeling under the weather,' they are not literally underneath any weather, but are conveying that they do not feel well. This usage of language is essential in poetry and creative writing, as it allows for the expression of complex ideas, emotions, and imagery beyond what literal words can convey.
