How we change what others think, feel, believe and do
Epanalepsis is the repetition of a word or words at both the beginning and end of a sentence or clause.
Do unto others as you would have them do unto you.
Buy this car and you'll be glad you decided to buy this today.
The king is dead; long live the king!
A question for which there is no answer is still a question, but an answer for which there is no question is no answer.
Repeated words do not have to be exactly at the start and end and a word or two outside them still creates epanalepsis.
Words at the beginning are more memorable due to the primacy effect, whilst words at the end are remembered more often due to the recency effect. Repeating the same words at the start and at the end thus has a 'double whammie' amplification.
Chiasmus is related as it is 'nested double-epanalepses'.
