Praise could be more on the level (7)
I believe the answer is:
flatter
'praise' is the definition.
(I know that flatter is a more specific form of the action praise)
'could be more on the level' is the wordplay.
'could be more' becomes 'ter' (I can't explain this - if you can you should believe this answer much more).
'on' is a charade indicator (letters next to each other).
'the level' becomes 'flat' (I've seen this in another clue).
'ter' after 'flat' is 'FLATTER'.
Can you help me to learn more?
(Other definitions for flatter that I've seen before include "more lifeless" , "Lavish compliments on (someone)" , "flannel" , "Over-praise" , "suit, looking good" .)
