A crazy suggestion, but it gets one moving (10)
I believe the answer is:
locomotion
'one moving' is the definition.
(thesaurus)
'a crazy suggestion but' is the wordplay.
'a crazy' becomes 'loco' (loco can informally mean mad).
'suggestion but' becomes 'motion' (I can't explain this - if you can you should give a lot more credence to this answer).
'loco'+'motion'='LOCOMOTION'
'it gets' acts as a 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 locomotion that I've seen before include "The power of movement" , "travel" , "progress" , "Travelling" , "It enables one to move" .)
