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 before)
'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" .)
