Objective restricted cat, as stated (8)
I believe the answer is:
enounced
'stated' is the definition.
The definition and answer can be both to do with communicating as well as being past participle verbs.
Perhaps you can see an association between them that I can't see?
'objective restricted cat' is the wordplay.
'objective' becomes 'end' (both can mean a purpose).
'restricted' is an insertion indicator.
'cat' becomes 'ounce' (ounce is a kind of cat).
'end' enclosing 'ounce' is 'ENOUNCED'.
'as' is the link.
Can you help me to learn more?
(Another definition for enounced that I've seen is " spoke with great precision".)
