Support me, perhaps, to get to top (9)
I believe the answer is:
uppermost
'get to top' is the definition.
(I've seen this before)
'support me perhaps' is the wordplay.
'perhaps' indicates an anagram.
'support'+'me'='supportme'
'supportme' is an anagram of 'UPPERMOST'.
'to' acts as a link.
(Other definitions for uppermost that I've seen before include "get to top" , "At or nearest to the top" , "Highest in place or rank" , "on top of the pile" , "Highest or most prominent" .)
