I can't answer, I'm here and there (6)
I believe the answer is:
passim
'here and there' is the definition.
(I've seen this in another clue)
'i can't answer i'm' is the wordplay.
'i can't answer' becomes 'pass' (you might say 'pass' to skip a question).
'pass'+'im'='PASSIM'
(Other definitions for passim that I've seen before include "(Lit.) throughout, everywhere" , "(Of references) at various places through the text" , "Throughout (a piece of writing) - frequently cited" , "At many points in book" .)
