In songs, be deceitful and turn red (6)
I believe the answer is:
lieder
'in songs' is the definition.
'lieder' can be an answer for 'songs' (lied is a kind of song). I'm unsure of the 'in' bit.
'be deceitful and turn red' is the wordplay.
'be deceitful' becomes 'lie' (I've seen this in another clue).
'and' means one lot of letters go next to another.
'turn' says the letters should be written in reverse.
'red' reversed gives 'der'.
'lie'+'der'='LIEDER'
Can you help me to learn more?
(Other definitions for lieder that I've seen before include "Relied on classical German song" , "works by Schubert" , "German Romantic songs for solo voice" , "numbers in German" , "Art songs for voice and piano" .)
