Brief assault on male aide (7)
I believe the answer is:
attache
'aide' is the definition.
(I've seen this in another clue)
'brief assault on male' is the wordplay.
'brief' means to remove the last letter (a shorter or briefer version of the word).
'assault' becomes 'attack' (synonyms).
'on male' becomes 'he' (he refers to a man. I am not sure about the 'on' bit.).
'attack' with its final letter taken off is 'attac'.
'attac'+'he'='ATTACHE'
Can you help me to learn more?
(Other definitions for attache that I've seen before include "Specialised envoy" , "A diplomat or military officer in a foreign country" , "Small rectangular document case" , "ambassador's assistant" , "Specialist diplomat" .)
