They both refer to the use of language in a non-literal way to create a more vivid, imaginative, or impactful effect.
Figurative language is a broader term that encompasses any use of language that deviates from its ordinary, literal meaning. This includes:
* Figures of speech: Specific literary devices that use figurative language, such as metaphors, similes, personification, hyperbole, etc.
* Other forms of figurative language: These might include idioms, proverbs, slang, or even creative uses of wordplay.
So, while "figure of speech" is a subset of "figurative language," they both describe the use of language in a way that goes beyond its literal meaning.
