Bound to be in a hole, apparently (4)
I believe the answer is:
leap
'bound' is the definition.
(I know that bound can be written as leap)
'in a hole apparently' is the wordplay.
'in' indicates a hidden word.
'LEAP' is hidden within 'a hole apparently'.
'to be' is the link.
(Other definitions for leap that I've seen before include "Spring suddenly" , "Jump a long way" , "Jump suddenly" , "Basket" , "Sort of year" .)
