Group of people a guerrilla captures (6)
I believe the answer is:
league
'group of' is the definition.
'league' can be an answer for 'group' (I've seen this before). I'm not sure about the 'of' bit.
'people a guerrilla captures' is the wordplay.
'captures' indicates the answer is hidden within the clue (I've seen 'captured' mean this).
'LEAGUE' is hidden within 'people a guerrilla'.
Can you help me to learn more?
(Other definitions for league that I've seen before include "Group of clubs; distance" , "Old unit of distance" , "band together" , "sporting group" , "The alliance extends over three nautical miles." .)
