Young winger, on the fringes for City, getting rise of ten grand (6)
I believe the answer is:
cygnet
'young winger on the fringes' is the definition.
I can't judge whether this definition defines the answer.
'city getting rise of ten grand' is the wordplay.
'city getting' becomes 'cy' (I am not sure about this - if you are sure you should believe this answer much more).
'rise of' shows that the letters should be reversed in order.
'grand' becomes 'g' ('G' can be a synonym of 'grand').
'ten'+'g'='teng'
'teng' in reverse letter order is 'gnet'.
'cy'+'gnet'='CYGNET'
'for' is the link.
Can you help me to learn more?
(Other definitions for cygnet that I've seen before include "Young bird of a particular type" , "Aquatic creature" , "Little swan" , "Young water-bird" , "Youthful swan" .)
