Meat sheds giving away cold roasts (8)
I believe the answer is:
lambasts
'cold roasts' is the definition.
Although both the answer and definition are verbs in their -s form, I can't see how they can define each other.
'meat sheds giving away' is the wordplay.
I cannot quite see how this works, but
'meat' could be 'lamb' (lamb is a type of meat) and 'lamb' is found in the answer.
'away' could be 'a' (abbreviation as used in sports fixtures) and 'a' is found within the answer.
The remaining letters 'sts' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for lambasts that I've seen is " Thrashes or scolds severely".)
