Soldier eccentrically accepting scouting mission (5)
I believe the answer is:
recce
'scouting mission' is the definition.
'recce' can be an answer for 'scouting' (thesaurus). I'm not certain of the 'mission' bit.
'soldier eccentrically accepting' is the wordplay.
'accepting' says the answer is hidden in the clue (the answer has been accepted by the clue).
'RECCE' is hidden in the letters of 'soldier eccentrically'.
Can you help me to learn more?
(Other definitions for recce that I've seen before include "Check out" , "Case" , "Military observation" , "See how the land lies (informal)" , "Survey (sl.)" .)
