Wild Tigers' by artist with right to be official (9)
I believe the answer is:
registrar
'be official' is the definition.
(I've seen this before)
'wild tigers' by artist with right' is the wordplay.
'wild' indicates anagramming the letters.
'by' says to put letters next to each other.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'with' is a charade indicator (letters next to each other).
'right' becomes 'r' (abbreviation).
'tigers' anagrammed gives 'regist'.
'regist'+'ra'+'r'='REGISTRAR'
'to' acts as a link.
(Other definitions for registrar that I've seen before include "certifies births and deaths" , "University administrator -- hospital doctor" , "Official recording births, deaths and marriages" , "Keeper of official records - hospital doctor" , "Wedding recorder" .)
