Wingers, singers, or a novice at tennis maybe (7)
I believe the answer is:
linnets
'wingers' is the definition.
(I've seen this before)
'novice at tennis maybe' is the wordplay.
'novice' becomes 'L' (as in a learner driver with L-plates on their car).
'at' means one lot of letters go next to another.
'maybe' is an anagram indicator.
'tennis' with letters rearranged gives 'innets'.
'l'+'innets'='LINNETS'
'singers or a' is the link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for linnets that I've seen before include "birds" , "wingers" , "Common finches" , "Would they tweet" .)
