Reveal secret in short communication left lying around? (3,2)
I believe the answer is:
let on
'reveal secret' is the definition.
'let on' can be an answer for 'reveal' (synonyms). I'm not sure about the 'secret' bit.
'short communication left lying around?' is the wordplay.
'short communication' becomes 'note' (I've seen this before).
'left' becomes 'l' (common abbreviation).
'lying around?' says the letters should be written in reverse.
'note'+'l'='notel'
'notel' reversed gives 'LET ON'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for let on that I've seen before include "Divulge info; pretend" , "Spill the beans" , "Reveal information" , "Allow to board, or pretend" , "Tell me" .)
