A stand of a strange new sort is brought in (7)
I believe the answer is:
rostrum
'a stand' is the definition.
(thesaurus)
'strange new sort is brought in' is the wordplay.
'strange' becomes 'rum' (similar in meaning).
'new' indicates anagramming the letters.
'is brought in' indicates putting letters inside.
'sort' is an anagram of 'ostr'.
'rum' placed around 'ostr' is 'ROSTRUM'.
'of a' acts as a link.
(Other definitions for rostrum that I've seen before include "Platform for public speaking" , "beak" , "Podium" , "Rum rots (anag)" , "stage" .)
