What yours truly does to save a couple of bums? (5)
I believe the answer is:
seats
'bums?' is the definition.
('seat' can be a synonym of 'bum')
'what yours truly does to save a couple' is the wordplay.
I cannot quite understand how this works, but
'a' is present in the answer.
'does' could be 'sets' ('set' can be a synonym of 'do') and 'sets' is located in the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Other definitions for seats that I've seen before include "Chairs, stools" , "Parliamentary constituencies" .)
