Winger's notes about badly made exercise machine (9)
I believe the answer is:
treadmill
'exercise machine' is the definition.
(I've seen this before)
'winger's notes about badly made' is the wordplay.
'winger's notes' becomes 'trill' (I can't explain this - if you can you should believe this answer much more).
'about' means one lot of letters goes inside another.
'badly' indicates an anagram.
'made' is an anagram of 'eadm'.
'trill' placed around 'eadm' is 'TREADMILL'.
Can you help me to learn more?
(Other definitions for treadmill that I've seen before include "Tiresome job" , "tedious routine" , "Walking or running exercise device" , "It enables one to work out" , "Situation of routine drudgery" .)
