Definition:
The term ‘periphrasis’ refers to the use of excessive language and surplus words to convey a meaning that could otherwise be conveyed with fewer words and in more direct a manner. The use of this literary device can be to embellish a sentence, to create a grander effect, to beat around the bush and to draw attention away from the crux of the message being conveyed.
Example:
Instead of simply saying “I am displeased with your behavior”, one can say, “the manner in which you have conducted yourself in my presence of late has caused me to feel uncomfortable and has resulted in my feeling disgruntled and disappointed with you”.
