Descends from carriage missing right stops (7)
I believe the answer is:
detains
'stops' is the definition.
(I've seen this in another clue)
'descends from carriage missing right' is the wordplay.
I cannot quite understand how this works, but
'from' could be 'in' (I've seen this in other clues) and 'in' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for detains that I've seen before include "Stops" , "Holds back" , "Delays" .)
