Explain to a rebel worried about answer (9)
I believe the answer is:
elaborate
'explain' is the definition.
(thesaurus)
'a rebel worried about answer' is the wordplay.
I cannot really see how this works, but
'a' is within the answer.
'worried' could be 'ate' (something worrying may eat someone up) and 'ate' is found in the answer.
This may be the basis of clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for elaborate that I've seen before include "Very ornate or complex" , "Explain details" , "Develop in more detail" , "Detailed, complicated" , "with added detail" .)
