From Dickens to Perry: The art of speaking eloquently

Most of us love to come up with a beautifully-crafted phrase from time to time, but few of us succeed.

A new book by Mark Forsyth called The Elements of Eloquence examines what makes a beautiful sentence.

Key elements include the AABA pattern (also known as diacope) which is very common: "Romeo, Romeo, wherefore art thou Romeo."

Another rhetorical device is antithesis - the use of opposites in the same sentence - as deployed by Charles Dickens and then singer Katy Perry.

First broadcast on the Today programme on Monday 11 November.
