Peacekeepers worry about gunmen finally being free? (6)
I believe the answer is:
unnail
'free?' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.
'peacekeepers worry about gunmen finally' is the wordplay.
'peacekeepers' becomes 'UN' (United Nations, peacekeeping organisation).
'worry' becomes 'ail' (I've seen this in another clue).
'about' is a charade indicator (letters next to each other).
'finally' indicates one should take the final letters.
The final letter of 'gunmen' is 'n'.
'ail' after 'n' is 'nail'.
'un'+'nail'='UNNAIL'
'being' is the link.
Can you help me to learn more?
(Another definition for unnail that I've seen is " Remove fixing spike from (something)".)
