Straight there, going round and round (6)
I believe the answer is:
hetero
'straight' is the definition.
(I've seen this before)
'there going round and round' is the wordplay.
'going round' is an anagram indicator.
'and' is a charade indicator (letters next to each other).
'round' becomes 'o' (round can mean a round object**).
'there' is an anagram of 'heter'.
'heter'+'o'='HETERO'
(Other definitions for hetero that I've seen before include "Prefix signifying other" , "Person attracted to the opposite sex (abbr)" , "Straight (abbr)" .)
