Social climber's rare visit abroad (9)
I believe the answer is:
arriviste
'social climber's' is the definition.
(I've seen this before)
'rare visit abroad' is the wordplay.
'abroad' is an anagram indicator (letters move around or go abroad).
'rare'+'visit'='rarevisit'
'rarevisit' with letters rearranged gives 'ARRIVISTE'.
(Other definitions for arriviste that I've seen before include "Upstart" , "Social climber" , "nouveaux riches" , "Ambitious self-seeker" , "Rare visit (anag) - person on the make" .)
