Attack originating in part of East Anglia? One’s behind that (9)
I believe the answer is:
offensive
'attack' is the definition.
(similar in meaning)
'originating in part of east anglia? one's behind that' is the wordplay.
I cannot really see how this works, but
'part' could be 'si' (si is a kind of part) and 'si' is located in the answer.
'of' could be 'o' and 'o' is found in the answer.
'east' could be 'e' (abbreviation) and 'e' is present in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for offensive that I've seen before include "Insulting, loathsome" , "Unpleasant - attack" , "that may cause wounding" , "Causing anger or annoyance" , "Causing anger or resentment" .)
