Angrily, try a lie, perhaps (7)
I believe the answer is:
irately
'angrily' is the definition.
(I've seen this in another clue)
'try a lie perhaps' is the wordplay.
'perhaps' indicates anagramming the letters.
'try'+'a'+'lie'='tryalie'
'tryalie' anagrammed gives 'IRATELY'.
(Other definitions for irately that I've seen before include "Cross style" , "Angrily" , "With great anger" .)
