Reveal nothing about European victor returning to follow United (6)
I believe the answer is:
unveil
'reveal' is the definition.
('unveil' can be a synonym of 'reveal')
'nothing about european victor returning to follow united' is the wordplay.
I cannot really understand how this works, but
'european' could be 'e' (abbreviation e.g. EU) and 'e' is present in the answer.
'victor' could be 'v' (phonetic alphabet: alpha, bravo, charlie etc.) and 'v' is located in the answer.
'nothing' could be 'nil' ('nil' can be a synonym of 'nothing') and 'nil' is found within the remaining letters.
'united' could be 'u' and 'u' is located in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for unveil that I've seen before include "bare" , "Reveal by removing a curtain" , "'Reveal, uncover (6)'" , "Expose or reveal, remove cover" , "Uncover, disclose" .)
