Is duck invading old Greek region offensive? (7)
I believe the answer is:
noisome
'offensive?' is the definition.
(I know that offensive can be written as noisome)
'is duck invading old greek region' is the wordplay.
'duck' becomes 'o' (resembles zero - 'duck' in cricket).
'invading' indicates putting letters inside.
'old greek region' becomes 'nome' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'is'+'o'='iso'
'iso' inserted within 'nome' is 'NOISOME'.
Can you help me to learn more?
(Other definitions for noisome that I've seen before include "Offensively malodorous" , "Nauseating" , "Evil-smelling, objectionable (7)" , "Nasty" , "Odorous" .)
