Something for the press: a girl dancing about (6)
I believe the answer is:
garlic
'something for the press' is the definition.
(as in a garlic press)
'a girl dancing about' is the wordplay.
'dancing' indicates an anagram.
'about' becomes 'c' (abbreviation for circa).
'a'+'girl'='agirl'
'agirl' with letters rearranged gives 'garli'.
'garli'+'c'='GARLIC'
(Other definitions for garlic that I've seen before include "something with strong smell" , "Pungent bulb hated by vampires" , "Aioli ingredient" , "Pungent bulb feared by vampires" , "Pungent bulbs" .)
