All this worker makes going on the horses? (7)
I believe the answer is:
saddler
'all this worker makes going on the horses?' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
This is the entire clue.
Can you help me to learn more?
(Other definitions for saddler that I've seen before include "Maker of seats for riders" , "Leather-worker" , "One makes leather goods for horses" , "I'll make seat" , "he'll offer you a seat" .)
