Three got moved at the same time (8)
I believe the answer is:
together
'at the same time' is the definition.
(synonyms)
'three got moved' is the wordplay.
'moved' is an anagram indicator.
'three'+'got'='threegot'
'threegot' is an anagram of 'TOGETHER'.
(Other definitions for together that I've seen before include "stable" , "Collectively" , "Level-headed" , "Well-controlled" , "tied" .)
