Mover put nuts on wheels (9)
I believe the answer is:
locomotor
'mover put nuts on wheels' is the definition.
I can't judge whether this definition defines the answer.
'nuts on wheels' is the wordplay.
'nuts' becomes 'loco' ('loco' can be a synonym of 'nuts'**).
'on' is a charade indicator (letters next to each other).
'wheels' becomes 'motor' (I've seen this before).
'loco'+'motor'='LOCOMOTOR'
Can you help me to learn more?
(Another definition for locomotor that I've seen is " For travel".)
