Hendiadys is a literary device that is used to express an idea through two different words that are grammatically connected. The word might not be familiar to most people, but there are a few synonyms that can be used interchangeably. One such synonym is the expression "double description," which is used to describe the same idea twice using different words. Another is the term "merism," which highlights the nature of a concept by dividing it into different parts. Other alternatives for hendiadys could be "two-noun compound" or "double noun." Whatever term is used, the idea remains the same; it is a technique used by writers and speakers globally, and one that allows for great creativity in communication.
