Elaborate description of docked lamb? (8)
I believe the answer is:
detailed
'elaborate description of docked lamb?' is the definition.
'detailed' can be an answer for 'elaborate' (I've seen this before). I'm not certain of the 'description of docked lamb?' bit.
'elaborate description of docked lamb?' is the wordplay.
'elaborate' becomes 'detail' (detailing is a kind of elaborating).
'description of docked lamb?' becomes 'ed' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'detail'+'ed'='DETAILED'
Can you help me to learn more?
(Other definitions for detailed that I've seen before include "Particular" , "Comprehensive" , "Minutely described" , "Exhaustive" , "Elaborate" .)
