Condemns baby sheep and donkey having testosterone injection (8)
I believe the answer is:
lambasts
'condemns' is the definition.
The definition and answer can be both to do with communicating as well as being verbs in their -s form.
Perhaps you can see a link between them that I can't see?
'baby sheep and donkey having testosterone injection' is the wordplay.
'baby sheep' becomes 'lamb' (I've seen this in another clue).
'and' means one lot of letters go next to another.
'donkey' becomes 'ass' (ass is a term for a donkey).
'having testosterone' becomes 't' (I can't explain this - if you can you should give a lot more credence to this answer).
'injection' indicates putting letters inside.
'ass' placed around 't' is 'asts'.
'lamb'+'asts'='LAMBASTS'
Can you help me to learn more?
(Another definition for lambasts that I've seen is " Thrashes or scolds severely".)
