We start to lean over and turn (5)
I believe the answer is:
wheel
'turn' is the definition.
(I've seen this before)
'we start to lean' is the wordplay.
'start to' says to take the initial letters.
'lean' becomes 'heel' ().
The first letter of 'we' is 'w'.
'w'+'heel'='WHEEL'
'over and' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for wheel that I've seen before include "- - of Fortune" , "Potters throw on it" , "Castor" , "Rotary object - don't reinvent it" , "ring" .)
