Question

A commercial that compares dry skin to a desert is using which literary device? alliteration irony metaphorical language literal language assonance

Answer 1

It's Metaphoric language.

Answer 2

We use metaphors when we take a word or a phrase to refer to something else, whether by symbolizing it or suggesting that is similar to another thing, person, idea or quality. Thus, they can not be taken literally.

When a commercial compares dry skin to a desert, it is using a metaphorical language, as it is using a "dry skin" to refer to something else "a desert".
