Maybe boxer attacked children (5)
I believe the answer is:
bitch
'maybe boxer' is the definition.
I can't tell whether this defines the answer.
'attacked children' is the wordplay.
'attacked' becomes 'bit' (I can't justify this - if you can you should believe this answer much more).
'children' becomes 'ch' (genealogical abbreviation).
'bit'+'ch'='BITCH'
Can you help me to learn more?
(Other definitions for bitch that I've seen before include "Female dog" , "Female animal" , "grouse" , "Malicious woman" , "Retriever likely to drop" .)
