Genuine sort of idols (5)
I believe the answer is:
solid
'genuine' is the definition.
(thesaurus)
'sort of idols' is the wordplay.
'sort of' is an anagram indicator.
'idols' anagrammed gives 'SOLID'.
(Other definitions for solid that I've seen before include "Sound; substantial" , "Hard; three dimensional" , "Concrete or reilable" , "Firmly constructed" , "continuous" .)
