Bird gets a morsel - a choice one (6)
I believe the answer is:
titbit
'a choice one' is the definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'bird gets a morsel' is the wordplay.
'bird' becomes 'tit' (tit is a kind of bird).
'gets' means one lot of letters go next to another.
'a morsel' becomes 'bit' ('bit' can be a synonym of 'morsel').
'tit'+'bit'='TITBIT'
Can you help me to learn more?
(Other definitions for titbit that I've seen before include "tiny amount of food" , "Pleasing scrap of gossip" , "Small tasty morsel" , "Choice bit of something, food or gossip" , "Small tasty bit of food" .)
