Tourist showing sense — wise man (9)
I believe the answer is:
sightseer
'tourist' is the definition.
(sightseer is a kind of tourist)
'sense wise man' is the wordplay.
'sense' becomes 'sight' (sighting is a kind of sensing).
'wise man' becomes 'seer' (I've seen this in other clues).
'sight'+'seer'='SIGHTSEER'
'showing' acts as a link.
(Other definitions for sightseer that I've seen before include "Visitor to famous locations" , "Tourist visiting scenes of interest" , "Tripper" , "Rubberneck" .)
