Greg Dole edited silly poem (8)
I believe the answer is:
doggerel
'silly poem' is the definition.
'doggerel' can be an answer for 'poem' (doggerel is a kind of poem). I'm not sure about the 'silly' bit.
'greg dole edited' is the wordplay.
'edited' indicates an anagram.
'greg'+'dole'='gregdole'
'gregdole' anagrammed gives 'DOGGEREL'.
Can you help me to learn more?
(Other definitions for doggerel that I've seen before include "Unpretentious verses" , "Poor quality comic or trivial verse" , "Very bad poetry or verse" , "Burlesque verse" , "Badly written verse" .)
