Some forms of embellishment are semantic, while others are verbal.
In semantic embellishments, beauty primarily lies in the relation between meanings, as when opposing ideas are brought together. Suitable paraphrasing may preserve the central effect.
In verbal embellishments, a particular wording, sound pattern, or arrangement matters more; altering it may remove the device. This is a distinction by principal basis, not a claim that semantic devices require no verbal skill or that verbal devices can ignore meaning.
