Goes round to stare curiously (7)
I believe the answer is:
rotates
'goes round' is the definition.
(I've seen this before)
'to stare curiously' is the wordplay.
'curiously' indicates an anagram.
'to'+'stare'='tostare'
'tostare' anagrammed gives 'ROTATES'.
(Other definitions for rotates that I've seen before include "Spins round" , "revolves" , "Turns round" , "Goes round" , "Turns around an axis" .)
