Slowly advanced to the hole (5)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
lento
'slowly' is the definition.
('lento' can be a synonym of 'slowly')
'advanced to the hole' is the wordplay.
'advanced' becomes 'lent' (money).
'to the hole' becomes 'o'.
'lent'+'o'='LENTO'
(Other definitions for lento that I've seen before include "Slow (music)" , "Slowly (mus.)" , "(Of tempo) slow" , "Musically low speed" , "How one scores slowly" .)
