Desperate Dan implores Bob, Eve and Anna, say (11)
I believe the answer is:
palindromes
'bob eve and anna say' is the definition.
I know that 'anna' relates to this answer.
'desperate dan implores' is the wordplay.
'desperate' indicates anagramming the letters (a desperate or pathetic spelling).
'dan'+'implores'='danimplores'
'danimplores' anagrammed gives 'PALINDROMES'.
Can you help me to learn more?
(Other definitions for palindromes that I've seen before include "Mum and Dad, for example" , "Eg, repaper, Hannah" , "Words reading the same both ways" , "eg Pop, DVD and Abba" .)
