Flyer, for example, pretty content (5)
I believe the answer is:
egret
'pretty content' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'flyer for example' is the wordplay.
'flyer' becomes 'ret' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'for' means one lot of letters go next to another (I've seen this in other clues).
'example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'ret' after 'eg' is 'EGRET'.
Can you help me to learn more?
(Other definitions for egret that I've seen before include "one with plume" , "Mainly white heron" , "White-plumed wader" , "White-feathered wading bird" , "Heron-like wader" .)
