Explained how to challenge Labor at education centre (10)
I believe the answer is:
elaborated
'explained how' is the definition.
The definition and answer can be both to do with communicating as well as being past participle verbs.
Maybe they are linked in a way I don't understand?
'challenge labor at education centre' is the wordplay.
'ELABORATED' is hidden within the letters.
But, I am unsure how the hidden word is indicated.
'to' is the link.
Can you help me to learn more?
(Another definition for elaborated that I've seen is " Added detail to (an account)".)
