Craved last bit of roly-poly taken home (7)
I believe the answer is:
yearned
'craved' is the definition.
(I've seen this before)
'last bit of roly-poly taken home' is the wordplay.
I cannot really see how this works, but
'bit' could be 'ear' (I have seen 'Bit of corn' mean 'ear' so perhaps 'bit' could also mean 'ear') and 'ear' is found in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for yearned that I've seen before include "Pined" , "Desired strongly and persistently" , "Felt longing (for something)" , "Longed (for something)" , "Desired - longed (for)" .)
