Retro-chic writer revoked chic sports target (7)
I believe the answer is:
ninepin
'sports target' is the definition.
'ninepin' can be an answer for 'target' (I've seen this before). I am not certain of the 'sports' bit.
'retro-chic writer revoked chic' is the wordplay.
'retro' says the letters should be written in reverse (retro is Latin for 'backwards').
'chic' becomes 'in'.
'writer' becomes 'pen' (something which writes).
'revoked' shows that the letters should be reversed in order (revoke means to take back).
'chic' becomes 'in'.
'in' written backwards gives 'ni'.
'pen' in reverse letter order is 'nep'.
'ni'+'nep'+'in'='NINEPIN'
Can you help me to learn more?
(Other definitions for ninepin that I've seen before include "Skittle" , "over one goes" , "target to knock over" , "game" , "Type of bowling" .)
