Say lie may be found out without difficulty (6)
I believe the answer is:
easily
'without difficulty' is the definition.
(synonyms)
'say lie may be' is the wordplay.
'may be' indicates anagramming the letters.
'say'+'lie'='saylie'
'saylie' anagrammed gives 'EASILY'.
'found out' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for easily that I've seen before include "With little difficulty" , "with little effort" , "Without difficulty or effort" , "Comfortably" , "Very probably" .)
