Teen oddly following Aida? Run! (7)
I believe the answer is:
operate
'run' is the definition.
(synonyms)
'teen oddly following aida?' is the wordplay.
'oddly' means one should take alternating letters (letters in odd-numbered positions).
'following' is a charade indicator (letters next to each other).
'aida?' becomes 'opera' (I've seen this in another clue).
The alternating letters of 'teen' are 'te'.
'te' after 'opera' is 'OPERATE'.
(Other definitions for operate that I've seen before include "Work as a surgeon" , "Work, function" , "Work - perform surgery" , "Carry out surgery" , "Perform surgery or run a machine" .)
