Stayed around stable (6)
I believe the answer is:
steady
'stable' is the definition.
('steady' can be similar in meaning to 'stable')
'stayed around' is the wordplay.
'around' indicates anagramming the letters.
'stayed' with letters rearranged gives 'STEADY'.
(Other definitions for steady that I've seen before include "Regular date" , "Not wobbling" , "Firmly fixed; reliable" , "Stable or regular" , "Calm and constant" .)
