How steeplejack might be paid to sweat? (8)
I believe the answer is:
'to sweat?' is the definition.
('perspire' can be a synonym of 'sweat')
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for perspire that I've seen before include "Swelter" , "Exude" , "Sweat (as a lady does?)" , "Sweat politely" , "for every shoot" .)
