A bride may have this coach (5)
I believe the answer is:
train
'this coach' is the definition.
(both can mean to instruct a sportsperson)
'a bride' is the wordplay.
I cannot quite understand how this works, but
'a' is present in the answer.
The remaining letters 'trin' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'may have' is the link.
Can you help me to learn more?
(Other definitions for train that I've seen before include "Teach; followers" , "Teach; series of gears" , "Suite; give practice (in)" , "Form of transport" , "Instruct - exercise" .)
