Answer:

Step-by-step explanation:
It's the part of the sentence that doesn't really add up and it's confusing to read. I'm not too sure, but from what I researched figurative languages are 'a way of expressing oneself that does not use a word's strict or realistic meaning' . It also used to explain a complicated idea or to add a creative flourish to the language.
Apologies if my English is a little wacky, it isn't really my main language- but I hope this helped.
