Skip in the Dolomites (4)
I believe the answer is:
omit
'skip' is the definition.
(I've seen this in another clue)
'in the dolomites' is the wordplay.
'in' indicates the answer is hidden within the clue.
'OMIT' is hidden within 'dolomites'.
(Other definitions for omit that I've seen before include "Leave out or exclude" , "Miss out" , "Exclude - neglect" , "Don't include" , "Leave out, perhaps in error" .)
