Distasteful thing first person on Italian island raised (13)
I believe the answer is:
objectionable
'distasteful' is the definition.
(thesaurus)
'thing first person on italian island raised' is the wordplay.
'thing' becomes 'object' (I've seen this before**).
'first person' becomes 'i'.
'italian island' becomes 'elba' (I've seen this before).
'raised' says the letters should be written in reverse.
'elba' in reverse letter order is 'able'.
'object'+'i'+'on'+'able'='OBJECTIONABLE'
(Other definitions for objectionable that I've seen before include "Repugnant" , "Distasteful - noble Jacobite (anag)" , "Offensive" , "Hateful" , "Obnoxious" .)
