Skip in the Dolomites (4)
I believe the answer is:
omit
'skip' is the definition.
(I know that skip is a kind of omit)
'in the dolomites' is the wordplay.
'in' indicates the answer is hidden within the clue.
'OMIT' is hidden in the letters of '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" .)
