Quote reportedly visionary traveller (9)
I believe the answer is:
sightseer
'traveller' is the definition.
(sightseer is a kind of traveller)
'quote reportedly visionary' is the wordplay.
'quote' becomes 'cite' ('cite' can be a synonym of 'quote').
'reportedly' indicates a 'sounds like' (homophone) clue.
'visionary' becomes 'seer' ('seer' can be a synonym of 'visionary').
'cite' is a homophone of 'sight'.
'sight'+'seer'='SIGHTSEER'
(Other definitions for sightseer that I've seen before include "Tripper" , "Visitor to famous locations" , "Rubberneck" , "Tourist visiting scenes of interest" .)
