Bird got beak into tasty morsel (6)
I believe the answer is:
titbit
'tasty morsel' is the definition.
(I've seen this before)
'bird got beak' is the wordplay.
'bird' becomes 'tit' (tit is a kind of bird).
'got beak' becomes 'bit' (I can't explain this - if you can you should give a lot more credence to this answer).
'tit'+'bit'='TITBIT'
'into' is the link.
Can you help me to learn more?
(Other definitions for titbit that I've seen before include "Delicacy" , "Choice bit of something, food or gossip" , "Small item of gossip" , "Small tasty bit of food" , "tiny amount of food" .)
