Carriage wheels broken by learner in Escort (6)
I believe the answer is:
gigolo
'escort' is the definition.
(term for a male escort)
'carriage wheels broken by learner in' is the wordplay.
'carriage wheels' becomes 'gig' (type of carriage).
'broken by' becomes 'oo' (I can't explain this - if you can you should believe this answer much more).
'learner' becomes 'l' (as in a learner driver with L-plates on their car).
'in' is an insertion indicator.
'oo' going around 'l' is 'olo'.
'gig'+'olo'='GIGOLO'
Can you help me to learn more?
(Other definitions for gigolo that I've seen before include "Hired male escort" , "Man supported by an older woman to be her lover" , "Kept man" , "Paid male lover" , "dancing partner" .)
