Escaped from tyranny (3)
I believe the answer is:
ran
'escaped' is the definition.
(ran away)
'from tyranny' is the wordplay.
'from' indicates the answer is hidden within the clue.
'RAN' is hidden in the letters of 'tyranny'.
(Other definitions for ran that I've seen before include "Moved fast or managed" , "11 on foot" , "Took a single" , "Tore" , "Managed; raced" .)
