In a funny way, I'm to skip (4)
I believe the answer is:
omit
'skip' is the definition.
(I know that skip is a more specific form of the action omit)
'in a funny way i'm to' is the wordplay.
'in a funny way' indicates an anagram (a funny or unusual order for the letters).
'im'+'to'='imto'
'imto' anagrammed gives 'OMIT'.
(Other definitions for omit that I've seen before include "Drop" , "Leave out, perhaps in error" , "Fail to use" , "Exclude; forget to include" , "Neglect to include" .)
