Use my pole when rambling (6)
I believe the answer is:
employ
'use' is the definition.
('employ' can be a synonym of 'use')
'my pole when rambling' is the wordplay.
'when rambling' is an anagram indicator (I've seen this in other clues).
'my'+'pole'='mypole'
'mypole' anagrammed gives 'EMPLOY'.
(Other definitions for employ that I've seen before include "Engage or hire for work" , "Draw on" , "Give job to (someone)" , "Take on (staff)" , "Put on the payroll" .)
