A girl more confused by rambling account (9)
I believe the answer is:
rigmarole
'rambling account' is the definition.
(I've seen this before)
'a girl more confused' is the wordplay.
'confused' indicates anagramming the letters.
'a'+'girl'+'more'='agirlmore'
'agirlmore' anagrammed gives 'RIGMAROLE'.
'by' acts as a link.
(Other definitions for rigmarole that I've seen before include "fuss" , "Complex procedure" , "Palaver" , "Long, complicated and confusing procedure" , "boring series" .)
