Lads with me spoilt old girl (6)
I believe the answer is:
damsel
'old girl' is the definition.
'damsel' can be an answer for 'girl'. I'm not sure about the 'old' bit.
'lads with me spoilt' is the wordplay.
'with' means one lot of letters go next to another.
'spoilt' indicates anagramming the letters.
'lads'+'me'='ladsme'
'ladsme' anagrammed gives 'DAMSEL'.
Can you help me to learn more?
(Other definitions for damsel that I've seen before include "Maid" , "Young lady of old, perhaps in distress" , "Maiden, often in distress" , "(Poetically) a young unmarried woman" , "Someone in distress?" .)
