The French tenor performed after that (5,2)
I believe the answer is:
later on
'that' is the definition.
Both the definition and answer are adverbs.
Maybe they are linked in a way I don't understand?
'the french tenor performed after' is the wordplay.
'the french' becomes 'la' ('the' in French).
'performed' is an anagram indicator.
'after' is a charade indicator (letters next to each other).
'tenor' with letters rearranged gives 'teron'.
'la'+'teron'='LATER ON'
Can you help me to learn more?
(Other definitions for later on that I've seen before include "in the future" , "Afterwards" , "this evening?" , "At a subsequent time" , "'Subsequently, afterward (5,2)'" .)
