In league with French, one provided bomb (7)
I believe the answer is:
unified
'in league with french one provided bomb' is the definition.
I can't tell whether this definition defines the answer.
'with french one provided bomb' is the wordplay.
'with' is a charade indicator (letters next to each other).
'french one' becomes 'un' ('one' in French).
'provided' becomes 'if' (eg 'provided it's sunny' means 'if it's sunny').
'bomb' becomes 'ied' (abbreviation for improvised explosive device).
'un' next to 'if' is 'unif'.
'unif'+'ied'='UNIFIED'
Can you help me to learn more?
(Other definitions for unified that I've seen before include "Joined together" , "Brought together as one" , "Made one" .)
